SUMMARY CMI

Tacrolimus Sandoz®

Consumer Medicine Information (CMI) summary

The full CMI on the next page has more details. If you are worried about using this medicine, speak to your doctor or pharmacist.

1. Why am I using Tacrolimus Sandoz

Tacrolimus Sandoz contains the active ingredient tacrolimus monohydrate.

Tacrolimus Sandoz is used so that your new liver, kidney, lung or heart will not be attacked or rejected by your body.

For more information, see Section 1. Why am I using Tacrolimus Sandoz? in the full CMI.

2. What should I know before I use Tacrolimus Sandoz?

Do not use if you have ever had an allergic reaction to Tacrolimus Sandoz, macrolide antibiotics, or any of the ingredients listed at the end of the CMI. Tacrolimus Sandoz and Tacrolimus XR Sandoz are not interchangeable.

For more information, see Section 2. What should I know before I use Tacrolimus Sandoz? in the full CMI.

3. What if I am taking other medicines?

Some medicines may interfere with Tacrolimus Sandoz and affect how it works.

1. Why am I using Tacrolimus Sandoz?

Tacrolimus Sandoz contains the active ingredient tacrolimus monohydrate, which is an immunosuppressive agent.

You have been given a new transplanted liver or kidney, lung or heart from another person because your own was no longer healthy. Your body recognises that this new organ is different from your other organs and will try to reject it by attacking it in the same way that it would attack germs that enter your body. This could make you become ill again. Tacrolimus Sandoz stops this attack; it is very important to take Tacrolimus Sandoz given to you by your doctor regularly so you're your new liver, kidney, lung or heart will not be attacked or rejected.

If you have been taking other medicines for this purpose, but are still feeling unwell, your doctor may change your treatment and begin giving you Tacrolimus Sandoz.

Your doctor may have prescribed Tacrolimus Sandoz for another reason.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

2. What should I know before I use Tacrolimus Sandoz?

Warnings

Do not use Tacrolimus Sandoz if:

  • you are allergic to any medicine containing tacrolimus, or other macrolides (these are antibiotics of the erythromycin family), or any of the ingredients listed at the end of this leaflet.
  • Always check the ingredients to make sure you can use this medicine.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body
  • rash, itching or hives on the skin

Do not use Tacrolimus Sandoz if the packaging is torn or shows signs of tampering. Do not use Tacrolimus Sandoz beyond the expiry date printed on the pack.

Check with your doctor if you:

  • are receiving ciclosporin immunosuppressive therapy.

If you have not told your doctor about any of the above, tell them before you start taking or are given Tacrolimus Sandoz.

Your doctor will advise you whether or not to take Tacrolimus Sandoz or if you need to adjust the dose or adapt your treatment.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

Check with your doctor if you are using oral contraceptives.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Tacrolimus Sandoz and affect how it works.

In particular, you should tell your doctor if you are taking or have recently taken medicines like:

  • antifungal medicines and antibiotics, particularly so-called macrolide antibiotics, used to treat infections e.g., ketoconazole, fluconazole, itraconazole, voriconazole, clotrimazole, miconazole, caspofungin, erythromycin, clarithromycin, josamycin, rifampicin, rifabutin and isoniazid
  • letermovir, used to prevent illness caused by CMV (human cytomegalovirus)
  • HIV protease inhibitors (e.g., ritonavir, nelfinavir, saquinavir), the booster medicine cobicistat, and combination tablets, or HIV non-nucleoside reverse transcriptase inhibitors (efavirenz, etravirine, nevirapine) used to treat HIV infection
  • HCV protease inhibitors (e.g., telaprevir, boceprevir, the combination ombitasvir/paritaprevir/ritonavir with or without dasabuvir, elbasvir/grazoprevir, and glecaprevir/pibrentasvir), used to treat hepatitis C infection
  • mycophenolic acid used to suppress the immune system to prevent transplant rejection
  • medicines for stomach ulcer and acid reflux (e.g., omeprazole, lansoprazole or cimetidine)
  • antiemetics, used to treat nausea and vomiting (e.g., metoclopramide)
  • cisapride or the antacid magnesium-aluminium-hydroxide, used to treat heartburn
  • the contraceptive pill or other hormone treatments with ethinylestradiol, hormone treatments with danazol
  • medicines used to treat high blood pressure or heart problems (e.g., nifedipine, nicardipine, diltiazem and verapamil)
  • anti-arrhythmic drugs (amiodarone) used to control arrhythmia (uneven beating of the heart)
  • medicines known as "statins" used to treat elevated cholesterol and triglycerides
  • carbamazepine, phenytoin or phenobarbital, used to treat epilepsy
  • metamizole, used to treat pain and fever
  • the corticosteroids prednisolone and methylprednisolone, belonging to the class of corticosteroids used to treat inflammations or suppress the immune system (e.g., in transplant rejection)
  • nefazodone, used to treat depression
  • herbal preparations containing St. John's wort (Hypericum perforatum) or extracts of Schisandra sphenanthera.

Tell your doctor if you are taking or need to take ibuprofen, amphotericin B, antibiotics (cotrimoxazole, vancomycin, or so-called aminoglycoside antibiotics such as gentamicin), or antivirals (e.g., acyclovir, ganciclovir, cidofovir, or foscarnet). These may worsen kidney or nervous system problems when taken together with Tacrolimus Sandoz.

Your doctor also needs to know if you are taking potassium supplements or potassium-sparing diuretics (e.g., amiloride, triamterene, or spironolactone), or the antibiotics trimethoprim or cotrimoxazole that may increase levels of potassium in your blood, certain pain killers (so-called NSAIDs, e.g., ibuprofen), anticoagulants, or oral medication for diabetic treatment, while you receive Tacrolimus Sandoz.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Tacrolimus Sandoz.

4. How do I use Tacrolimus Sandoz?

How much to take

  • You can only get Tacrolimus Sandoz from your doctor. Your dose will be calculated according to your weight, age and medical condition. As your health and the function of your new liver or kidney, lung or heart can be affected by how much medicine you take, it is normal that your doctor collects samples of blood and urine at regular intervals. This is in order to test whether your medicine requires adjustment.

When to take Tacrolimus Sandoz

  • Tacrolimus Sandoz should be taken in two doses (e.g. morning and evening) each day.

How to take Tacrolimus Sandoz

  • Take the capsule from the blister pack and swallow it whole with plenty of water. Do not take this medicine with grapefruit juice as it contains substances that interfere with the action of Tacrolimus Sandoz.
  • Tacrolimus Sandoz capsules should generally be taken on an empty stomach or at least 1 hour before a meal or 2 to 3 hours after a meal. You must never change the dose yourself even if you are feeling better. It is very important that you keep taking this medicine so that your body will not reject your new liver, kidney lung or heart.
  • If you accidentally take a larger dose than recommended, tell your doctor immediately.
  • If you do not understand the instructions provided with this medicine, ask your doctor or pharmacist for help.

How long to take Tacrolimus Sandoz

  • Continue taking your medicine for as long as your doctor tells you.

If you forget to use Tacrolimus Sandoz

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose you missed.

If you have missed more than one dose, or if you are not sure what to do, ask your doctor or pharmacist.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints.

If you use too much Tacrolimus Sandoz

If you think that you have used too much Tacrolimus Sandoz, you may need urgent medical attention.

You should immediately:

  • phone the Australian Poisons Information Centre
    (by calling 13 11 26), or the New Zealand National Poisons Information Centre (by calling 0800 POISONS or 0800 764 766), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using Tacrolimus Sandoz?

Things you should do

  • Always follow your doctor's instructions carefully.
  • Tell your doctor if you become pregnant while taking Tacrolimus Sandoz
  • Tacrolimus Sandoz suppresses your immune system by lowering your body's immune defence system. This increases your risk of skin cancer and other cancers while taking Tacrolimus Sandoz. You should always protect yourself from the sun, wear sunscreen, a hat and protective clothing.
  • If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Tacrolimus Sandoz.

Remind any doctor, dentist or pharmacist you visit that you are using Tacrolimus XR Sandoz.

Things you should not do

  • Do not take Tacrolimus Sandoz to treat any other complaints unless your doctor says so.
  • Do not give your medicine to anyone else, even if their symptoms are similar to yours.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how Tacrolimus Sandoz affects you.

Tacrolimus Sandoz may cause visual or nervous disturbances in some people. If affected, do not drive or operate machinery.

Effects of food and alcohol

Food reduces the absorption of Tacrolimus Sandoz. Therefore, the capsules should be taken at least 1 hour before a meal or 2 to 3 hours after a meal.

Drinking alcohol

Tell your doctor if you drink alcohol.

Looking after your medicine

  • Use all the Tacrolimus Sandoz capsules within 12 months of opening the aluminum wrapper. Do not use after printed expiry date.
  • Keep Tacrolimus Sandoz capsules in the blisters until it is time to take them. If you take it out of its original container it may not keep well.
  • Store Tacrolimus Sandoz capsules where temperatures stay below 30°C.
  • Protect from light and moisture.

Store it in a cool dry place away from moisture, heat or sunlight; for example, do not store it:

  • in the bathroom or near a sink, or
  • in the car or on window sills.

Heat and dampness can destroy some medicines.

Keep it where young children cannot reach it.

A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.

Getting rid of any unwanted medicine

If you no longer need to use this medicine or it is out of date, take it to any pharmacy for safe disposal.

Do not use this medicine after the expiry date.

4 Clinical Particulars

4.1 Therapeutic Indications

Tacrolimus Sandoz and Tacrolimus XR Sandoz are indicated for use as an adjunct to liver, kidney, lung or heart allograft transplantation in adults and children.

4.2 Dose and Method of Administration

Dosage.

The dosage recommendations given below for oral administration should act as a guideline. Tacrolimus Sandoz and Tacrolimus XR Sandoz doses should be adjusted according to individual patient requirements.

Method of administration.

It is recommended that the oral daily dose of Tacrolimus Sandoz be taken in two divided doses in the evening and morning.
It is recommended that the oral daily dose of Tacrolimus XR Sandoz be administered once daily in the morning.
Tacrolimus Sandoz and Tacrolimus XR Sandoz should be taken on an empty stomach or at least one hour before or two to three hours after a meal to achieve maximal absorption (see Section 5.2 Pharmacokinetic Properties, Absorption).
Tacrolimus Sandoz and Tacrolimus XR Sandoz capsules should be taken immediately following removal from the blister. The capsules should be swallowed with fluid, preferably water.

Instructions for use and handling.

Based on immunosuppressive effects of tacrolimus, inhalation or direct contact with skin or mucous membranes of injection solutions or powder contained in tacrolimus products should be avoided during preparation. If such contact occurs, wash the skin and eyes.

Use in transplants.

Liver transplantation.

Tacrolimus therapy should commence at 0.10 to 0.20 mg/kg/day administered as two divided doses for Tacrolimus Sandoz or as total daily dose for Tacrolimus XR Sandoz. Administration should start approximately six hours after the completion of liver transplant surgery.

Kidney transplantation.

Tacrolimus therapy should commence at 0.15 to 0.30 mg/kg/day administered as two divided doses for Tacrolimus Sandoz or as total daily dose for Tacrolimus XR Sandoz. Administration should start within 24 hours of kidney transplant surgery.

Lung transplantation.

Tacrolimus therapy should commence at 0.10 to 0.30 mg/kg/day administered as two divided doses for Tacrolimus Sandoz or as total daily dose for Tacrolimus XR Sandoz. Administration should start within 24 hours of lung transplant surgery.

Heart transplantation.

Tacrolimus therapy should commence at 0.075 mg/kg/day administered as two divided doses for Tacrolimus Sandoz or as total daily dose for Tacrolimus XR Sandoz. Administration should start within 24 hours of heart transplant surgery.

Further information for all indications follows.

Infants and children.

Higher mg/kg doses may be required in children compared with adults to achieve the same tacrolimus blood concentration.

Therapy dose levels for kidney, liver, lung or heart allograft rejection resistant to existing immunosuppressive regimens.

In patients experiencing rejection episodes which are unresponsive to conventional immunosuppressive therapy, Tacrolimus Sandoz and Tacrolimus XR Sandoz treatment should begin with the initial dose recommended for primary immunosuppression in that particular allograft.

Conversion.

Conversion of Tacrolimus Sandoz treated patients to Tacrolimus XR Sandoz.

Allograft transplant patients maintained on twice daily Tacrolimus Sandoz capsules dosing requiring conversion to once daily Tacrolimus XR Sandoz should be converted on a 1:1 (mg:mg) total daily dose basis. Tacrolimus XR Sandoz should be administered in the morning. Following conversion, tacrolimus trough levels should be monitored and if necessary dose adjustments made to maintain similar systemic exposure.
In stable patients converted from Tacrolimus Sandoz (twice daily dosing) to Tacrolimus XR Sandoz (once daily dosing) on a 1:1 (mg:mg) total daily dose basis, the systemic exposure to tacrolimus (AUC0-24) for Tacrolimus XR Sandoz was approximately 10% lower than that for Tacrolimus Sandoz. The relationship between tacrolimus trough levels (C24) and systemic exposure (AUC0-24) for Tacrolimus XR Sandoz is similar to that of Tacrolimus Sandoz. When converting from Tacrolimus Sandoz capsules to Tacrolimus XR Sandoz tacrolimus trough levels should be measured prior to conversion and within two weeks after conversion. Dose adjustments should be made to ensure that similar systemic exposure is maintained.
In de novo kidney and liver transplant patients AUC0-24 of tacrolimus for Tacrolimus XR Sandoz on Day 1 was 30% and 50% lower respectively, when compared with that for Tacrolimus Sandoz at equivalent doses. By Day 4, systemic exposure as measured by trough levels is similar for both kidney and liver transplant patients with both formulations. Careful and frequent monitoring of tacrolimus trough levels is recommended in the first two weeks post-transplant with Tacrolimus XR Sandoz to ensure adequate drug exposure in the immediate post-transplant period. As tacrolimus is a substance with low clearance, adjustments to the Tacrolimus XR Sandoz dose regimen may take several days before steady state is achieved.

Conversion from ciclosporin to Tacrolimus Sandoz or Tacrolimus XR Sandoz.

Care should be taken when converting patients from ciclosporin-based to tacrolimus-based therapy (see Section 4.4 Special Warnings and Precautions for Use, Conversion between agents; Section 4.5 Interactions with Other Medicines and Other Forms of Interactions). Tacrolimus based therapy should be initiated after considering ciclosporin blood concentrations and the clinical condition of the patient. Dosing should be delayed in the presence of elevated ciclosporin blood levels. In practice, tacrolimus based therapy has been initiated 12-24 hours after discontinuation of ciclosporin. Monitoring of ciclosporin blood levels should be continued following conversion as the clearance of ciclosporin might be affected.

Conversion between tacrolimus formulations.

Differences between oral formulations of tacrolimus can lead to important differences in systemic exposure to tacrolimus. Inadvertent or unsupervised switching between formulations is unsafe and could lead to graft rejection or increased incidence of side effects. Therefore, it is appropriate to prescribe and dispense tacrolimus by tradename, taking care to specify appropriate daily dosing (e.g. Tacrolimus Sandoz - twice daily dosing, Tacrolimus XR Sandoz - once daily dosing). Patients must only be switched from one tacrolimus formulation to another under the close supervision of a transplant specialist.

Dose adjustments in special populations.

Use in the elderly.

Experience in the elderly is limited. There is no evidence presently available to suggest that doses should be altered in elderly patients.

Use in patients with renal insufficiency.

No dose adjustment is required. However, careful monitoring of renal function is recommended.

Use in patients with hepatic insufficiency.

Tacrolimus is extensively metabolised by the liver. In patients with liver impairment dose reduction is recommended.
Tacrolimus is normally administered together with other immunosuppressive drugs. In isolated cases, successful maintenance therapy with tacrolimus alone has been described. Tacrolimus should not be given concurrently with ciclosporin.
If allograft rejection or adverse events occur, alteration in the immunosuppressive regimen should be considered.
Administration of Tacrolimus Sandoz or Tacrolimus XR Sandoz should commence as soon as practicable. In some liver transplantation patients, therapy has commenced orally by administering the capsule contents suspended in water, via an intranasal gastric tube.

Race.

In comparison to Caucasians, black patients may require higher tacrolimus doses to achieve similar trough levels.

Gender.

There is no evidence that male and female patients require different doses to achieve similar trough levels.

Monitoring advice.

Monitoring of tacrolimus whole blood trough concentrations in conjunction with other laboratory and clinical parameters is considered an essential aid to patient management for the evaluation of rejection, toxicity, dose adjustments and compliance. Factors influencing frequency of monitoring include but are not limited to hepatic or renal dysfunction, the addition or discontinuation of potentially interacting drugs and the post-transplant time. Blood trough concentration monitoring is not a replacement for renal or liver function monitoring and tissue biopsies.
Various assays have been used to measure blood or plasma concentrations of tacrolimus. Comparison of the concentrations in published literature to patient concentrations should be made with care and knowledge of the assay methods employed.
Trough blood concentrations should be measured at 12 hours after a Tacrolimus Sandoz dose or 24 hours after a Tacrolimus XR Sandoz dose. The majority of patients (adults and children) can be successfully managed if the trough blood concentrations are maintained within the following range.

Liver transplant.

5 to 20 nanogram/mL for the first three months, 5 to 15 nanogram/mL thereafter.

Kidney transplant.

10 to 20 nanogram/mL for the first three months, 5 to 15 nanogram/mL thereafter.

Heart transplant.

10 to 20 nanogram/mL for the first three months, 5 to 15 nanogram/mL thereafter.

Lung transplant.

10 to 20 nanogram/mL for the first month, then 5 to 15 nanogram/mL thereafter.
During the first months post-transplant, monitoring of the following parameters should be undertaken on a routine basis: blood pressure, ECG, visual status, blood glucose levels, electrolytes (particularly potassium), creatinine, blood urea nitrogen (BUN), urinary output, haematology parameters, coagulation values, and liver and renal function tests. If clinically relevant changes are seen, adjustment of the immunosuppressive regimen should be considered.
Post-transplant improvement in the condition of the patient may alter the pharmacokinetics of Tacrolimus Sandoz and Tacrolimus XR Sandoz. This should be considered when deciding upon a maintenance regimen.

Compatibility.

Tacrolimus Sandoz and Tacrolimus XR Sandoz is incompatible with PVC plastics. Tubing, syringes, and other equipment used to administer tacrolimus should not contain PVC.

4.3 Contraindications

Tacrolimus Sandoz and Tacrolimus XR Sandoz are contraindicated in patients hypersensitive to tacrolimus or other macrolides, or to other ingredients of the capsules.

4.4 Special Warnings and Precautions for Use

Tacrolimus therapy requires careful monitoring in hospital units equipped and staffed with adequate laboratory and supportive medical resources. The medicine should only be prescribed, and changes in immunosuppressive therapy should be initiated, by physicians experienced in immunosuppressive therapy and the management of transplant patients. The physician responsible for maintenance therapy should have complete information requisite for the follow-up of the patient.

Post-transplant diabetes mellitus (PTDM).

Post-transplant insulin dependent diabetes mellitus (PTDM: use of insulin for 30 or more consecutive days, with < five day gap, by patients without a prior history of insulin or noninsulin dependent diabetes mellitus) was reported in 20% (30/151) and 6% (17/281) of tacrolimus treated kidney transplant patients in the US and European randomised trials, respectively. The median time to onset of PTDM was 68 days. Insulin dependence was reversible in 15% of these patients at one year and in 50% at two years post-transplant. Black and Hispanic patients were found to be at increased risk of development of PTDM in the US trial. The risk/ benefit ratio should be carefully considered before using tacrolimus in kidney transplant patients with a pretransplant diabetic condition.
In liver transplantation PTDM was reported in 18% (42/239) and 11% (26/239) of tacrolimus treated patients and was reversible in 45 and 31% of these patients at one year post-transplant in the US and European randomised trials, respectively.
Insulin dependent post-transplant diabetes mellitus was reported in 13% (10/75) and 22% (29/132) of tacrolimus treated heart transplant patients receiving mycophenolate mofetil or azathioprine and was reversible in 30 and 17% of these patients at one year post-transplant in the US and European randomised studies, respectively.

Neurotoxicity.

Neurological and CNS disorders have been reported with tacrolimus therapy. Symptoms include tremor, headache, changes in motor function, sensory function or mental status, insomnia, seizures, coma and delirium. Patients experiencing such events should be carefully monitored. In cases of severe or worsening neurological disorder, adjustment of the immunosuppressive regimen should be considered.

Posterior reversible encephalopathy syndrome (PRES).

Patients treated with tacrolimus have been reported to develop posterior reversible encephalopathy syndrome (PRES). If patients taking tacrolimus present with symptoms indicating PRES such as headache, altered mental status, seizures, and visual disturbances, a radiological procedure (e.g. MRI) should be performed. If PRES is diagnosed, adequate blood pressure and seizure control and immediate discontinuation of systemic tacrolimus is advised. Most patients completely recover after appropriate measures are taken.

Pure red cell aplasia (PRCA).

Cases of pure red cell aplasia (PRCA) have been reported in patients treated with tacrolimus. All patients reported risk factors for PRCA such as parvovirus B19 infection, underlying disease or concomitant medications associated with PRCA.

Nephrotoxicity.

Tacrolimus can cause renal impairment charactered by increases in serum creatinine as a result of a reduced glomerular filtration rate, particularly when used in high doses. These changes have been observed to be dose dependent and improvements have been associated with reduced dosing. The mechanism leading to these changes is not fully understood. Use of tacrolimus with sirolimus in heart transplantation patients in a US study was associated with increased risk of renal function impairment, and is not recommended. Patients with impaired renal function should be monitored closely as the dosage of tacrolimus may need to be reduced.
Care should be taken in using tacrolimus with other nephrotoxic drugs. In particular, tacrolimus should not be used simultaneously with ciclosporin. Tacrolimus or ciclosporin should be discontinued at least 24 hours prior to initiating the other. In the presence of elevated tacrolimus or ciclosporin concentrations, dosing with the other drug usually should be further delayed.

Hyperkalaemia.

Mild to severe hyperkalaemia was reported in patients treated with tacrolimus, especially in patients with renal impairment. Patients may require treatment and should avoid high dietary potassium intake. Serum potassium levels should be monitored and potassium sparing diuretics should not be used during tacrolimus therapy.

Vaccinations.

As with other immunosuppressants, response to vaccination during treatment with tacrolimus may be less effective. The use of live attenuated vaccines should be avoided.

Gastrointestinal disorders.

Gastrointestinal perforation has been reported in patients treated with tacrolimus, although all cases were considered a complication of transplant surgery or accompanied by infection, diverticulum, or malignant neoplasm. As gastrointestinal perforation is a medically important event that may lead to a life threatening or serious condition, adequate treatments including surgery should be considered immediately after a suspect symptom occurs.

Potential interactions.

When substances with a potential for interaction (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions) particularly strong inhibitors of CYP3A4 (such as telaprevir, boceprevir, ritonavir, ketoconazole, voriconazole, itraconazole or clarithromycin) or inducers of CYP3A4 (such as rifampin, rifabutin) are being combined with tacrolimus, tacrolimus blood levels should be monitored to adjust the tacrolimus dose as appropriate in order to maintain similar tacrolimus exposure.

Malignancies.

As with other potent immunosuppressive compounds, patients treated with tacrolimus are at increased risk of developing lymphomas and other malignancies, particularly of the skin. The risk appears to be related to the intensity and duration of immunosuppression rather than to the use of any specific agent. Exposure to sunlight and ultraviolet (UV) light should be limited by wearing protective clothing and using a sunscreen with a high protection factor.
Lymphoproliferative disorder (LPD) related to Epstein-Barr virus (EBV) infection has been reported in immunosuppressed organ transplant recipients. In patients switched to tacrolimus, this may be attributable to over immunosuppression before commencing therapy with this agent. Very young (< 2 years), EBV seronegative children have been reported to have an increased risk of developing lymphoproliferative disorders. Therefore, in this patient group, EBV serology should be ascertained before starting treatment with tacrolimus. During treatment, careful monitoring is recommended.

Infections.

Like other immunosuppressants, tacrolimus predisposes patients to the development of a variety of bacterial, fungal, parasitic and viral infections. Oversuppression of the immune system can also increase susceptibility to opportunistic infections, sepsis and fatal infections.
Among these conditions are BK virus associated nephropathy, JC virus associated progressive multifocal leukoencephalopathy (PML) and CMV infection. These infections are often related to a high total immunosuppressive burden and may lead to serious or fatal conditions that physicians should consider in the differential diagnosis in immunosuppressed patients with deteriorating renal function or neurological symptoms.

Hypertension.

Hypertension is a common adverse effect of tacrolimus therapy. Antihypertensive therapy may be required; the control of blood pressure can be accomplished with any of the common antihypertensive agents. Since tacrolimus may cause hyperkalaemia, potassium sparing diuretics should be avoided. While calcium channel blocking agents can be effective in treating tacrolimus associated hypertension, care should be taken since interference with tacrolimus metabolism may require a dosage reduction.

Myocardial hypertrophy.

Ventricular hypertrophy or hypertrophy of the septum, reported as cardiomyopathies have been observed in a few cases in association with administration of tacrolimus. Most of these have been reversible, occurring primarily in patients having tacrolimus blood trough levels higher than the recommended level. Mean tacrolimus whole blood trough concentrations during the period prior to diagnosis of myocardial hypertrophy in 20 patients with pretreatment and post-treatment echocardiograms ranged from 10.6 to 53.3 nanogram/mL in infants (n = 10, age 0.4 to 2 years), 4.0 to 45.7 nanogram/mL in children (n = 7, age 2 to 15 years) and 10.9 to 24.3 nanogram/mL in adults (n = 3, age 37 to 45 years). Other factors observed to increase the risk of these clinical conditions are, for example, previously existing heart diseases, corticosteroid usage, hypertension, renal or hepatic dysfunction and fluid overload. Accordingly, high risk patients should be monitored, e.g. with echocardiography or ECG. If abnormalities develop, dose reduction of tacrolimus therapy or change of treatment to other immunosuppressive agent should be considered.

QT interview prolongation.

Tacrolimus may prolong the QT interval and may cause torsades de pointes. Caution should be exercised in patients with known risk factors for QT prolongation (including, but not limited to, congenital or acquired QT prolongation, concomitant medications known to prolong the QT interval or known to increase tacrolimus exposure).

Thrombotic microangiopathy (TMA) (including haemolytic uraemic syndrome (HUS) and thrombotic thrombocytopenic purpura (TTP)).

Thrombotic microangiopathies may have a multifactorial etiology. Risk factors for TMA that can occur in transplant patients include, for example, severe infections, graft-versus-host disease (GVHD), human leukocyte antigen (HLA) mismatch, the use of calcineurin inhibitors and mammalian target of rapamycin (mTOR) inhibitors. These risk factors may either alone or as a combination effect contribute to the risk of TMA.
Concurrent use of tacrolimus and mTOR inhibitors may contribute to the risk of TMA.

Conversion between agents.

Conversion between tacrolimus formulations.

Various dosage forms of tacrolimus are available, including immediate release oral dosage forms, prolonged release dosage forms and injectable dosage forms*. Medication errors have resulted in incorrect dosing or unsupervised switching between tacrolimus dosage forms. This has led to serious adverse events, including graft rejection, or other side effects which could be a consequence of either under exposure or over exposure to tacrolimus. Therefore, it is appropriate to prescribe and dispense tacrolimus by tradename, taking care to specify appropriate daily dosing (i.e. Tacrolimus Sandoz - twice daily dosing and Tacrolimus XR Sandoz - once daily dosing). It should be emphasised that patients, once titrated to an effective dose of a particular dosage form of tacrolimus, should not be changed to another dosage form of tacrolimus without blood trough level monitoring, clinical assessment and re-titration (see Section 4.2 Dose and Method of Administration, Conversion).
*Not all dosage forms are marketed by Sandoz but are available in other brands.

Conversion from ciclosporin.

Tacrolimus should not be administered concurrently with ciclosporin as the half-life of the latter may be increased. Synergistic/ additive nephrotoxic effects can also occur. Care should be taken when administering tacrolimus to patients who have previously received ciclosporin and when converting patients from ciclosporin to tacrolimus based therapy. It is recommended that ciclosporin blood levels are monitored prior to the administration of tacrolimus. The most appropriate time to initiate tacrolimus therapy should be based upon information on ciclosporin blood levels and the clinical condition of the patient. Dosing may be delayed in the presence of elevated ciclosporin levels. Monitoring of ciclosporin blood levels should be continued following conversion as the clearance of ciclosporin may be affected. A 24-hour interval between stopping ciclosporin and starting tacrolimus has been commonly used.
Patients switched to tacrolimus rescue therapy should not be given anti-lymphocyte treatment concomitantly.

Use in hepatic impairment.

Tacrolimus is extensively metabolised by the liver. In patients with liver impairment, dose reduction is recommended (see Section 4.2 Dose and Method of Administration, Dose adjustments in special populations).

Use in renal impairment.

No dose adjustment is required. However, careful monitoring of renal function is recommended. (See Section 4.2 Dose and Method of Administration, Dose adjustments in special populations.)

Use in the elderly.

Experience in the elderly is limited. There is no evidence presently available to suggest that doses should be altered in elderly patients. (See Section 4.2 Dose and Method of Administration, Dose adjustments in special populations.)

Paediatric use.

Higher mg/kg doses may be required in children compared with adults to achieve the same tacrolimus blood concentration. It is recommended that the initial oral doses should be 0.15 - 0.30 mg/kg/day as two divided doses. (See Section 4.2 Dose and Method of Administration.)

Effects on laboratory tests.

No data available.

4.5 Interactions with Other Medicines and Other Forms of Interactions

Metabolic interactions.

See Table 1.

Inhibitors of metabolism.

See Table 2.

Inducers of metabolism.

See Table 3.

Effect of tacrolimus on the metabolism of other drugs.

See Table 4.

Other potential interactions that may increase systemic exposure of tacrolimus.

Prokinetic agents such as metoclopramide and cisapride; cimetidine; magnesium-aluminium-hydroxide.

Other interactions, which have led to clinically detrimental effects.

See Table 5.

Protein binding considerations.

See Table 6.

Other considerations.

Combination with therapy with mycophenolic acid (MPA) products: caution should be exercised when switching combination therapy from ciclosporin to tacrolimus and vice versa. Exposure to MPA is higher with tacrolimus co-administration than that with ciclosporin coadministration because ciclosporin interrupts the enterohepatic recirculation of MPA while tacrolimus does not. Therapeutic drug monitoring of MPA is recommended.
Impact of direct-acting antiviral (DAA) therapy: the pharmacokinetics of tacrolimus may be impacted by changes in liver function during DAA therapy, related to clearance of HCV virus. A close monitoring and potential dose adjustment of tacrolimus is warranted to ensure continued efficacy and safety.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

Tacrolimus subcutaneously administered to male rats at doses of 2 or 3 mg/kg/day resulted in a dose-related decrease in sperm count.
(Category C)
In reproduction studies in rats and rabbits, adverse effects on the foetus were observed mainly at dose levels that were toxic to the dams. Tacrolimus given orally at 1.0 mg/kg (0.8 to 2.2 times the clinical dose range based on body surface area) to male and female rats, prior to and during mating, as well as to dams during gestation and lactation, was associated with embryolethality and adverse effects on female reproduction which were indicated by a higher rate of post-implantation loss and increased numbers of undelivered and nonviable pups. When given at 3.2 mg/kg (2.6 to 6.9 times the clinical dose range based on body surface area), tacrolimus was associated with maternal and paternal toxicity as well as reproductive toxicity including marked adverse effects on estrus cycles, parturition, pup viability, and pup malformations.
Human data show that tacrolimus is able to cross the placenta.
There are no adequate and well controlled studies in pregnant women. There is data from a voluntary pregnancy exposure registry (Transplantation Pregnancy Registry International (TPRI)) that monitors outcomes of pregnancy in female transplant recipients and those fathered by male transplant recipients exposed to immunosuppressants including tacrolimus.
Safety data from postmarketing surveillance and the TPRI suggest infants of organ transplant recipients using immunosuppressive medications including tacrolimus have an increased risk for miscarriage, pre-term delivery (< 37 weeks), low birth weight (< 2500 g), birth defects/congenital anomalies and fetal distress.
Tacrolimus use may also be associated with hyperglycemia or diabetes in pregnancy in the absence of pre-existing diabetes or gestational. Monitor maternal blood glucose levels regularly.
Tacrolimus may exacerbate hypertension in pregnant women and increase pre-eclampsia. Monitor and control blood pressure.
Females and males of reproductive potential should consider the use of appropriate contraception prior to starting treatment with tacrolimus.
The use of tacrolimus during pregnancy has been associated with neonatal hyperkalaemia and renal dysfunction. There is a risk for premature delivery. Cases of spontaneous abortion have been reported. Tacrolimus should be used during pregnancy only if the potential benefit to the mother justifies potential risk to the foetus.
 Tacrolimus is excreted into breast milk. It is, therefore, recommended that mothers should not breastfeed while receiving tacrolimus.

4.7 Effects on Ability to Drive and Use Machines

Tacrolimus may cause visual and neurological disturbances. Patients treated with tacrolimus who are affected by such disorders should not drive a car or operate dangerous machinery. This effect may be enhanced if tacrolimus is administered in association with alcohol.

4.8 Adverse Effects (Undesirable Effects)

The adverse drug effect profile associated with immunosuppressive agents is often difficult to establish owing to the underlying disease and the concurrent use of multiple medications.
The most commonly reported adverse drug reactions (occurring in > 10% of patients) are tremor, renal impairment, hyperglycaemic conditions, diabetes mellitus, hyperkalaemia, infections, hypertension and insomnia.
Many of the adverse drug effects stated below are reversible and/or respond to dose reduction. Oral administration appears to be associated with a lower incidence of adverse drug effects compared with intravenous use. Adverse drug effects are listed below in descending order by frequency of occurrence: very common (> 1/10); common (> 1/100, < 1/10); uncommon (> 1/1000, < 1/100); rare (> 1/10,000, < 1/1000); very rare (< 1/10,000, including isolated reports).

Infections and infestations.

As is well known for other potent immunosuppressive agents, patients receiving tacrolimus are frequently at increased risk for infections (viral, bacterial, fungal, protozoal). The course of pre-existing infections may be aggravated. Both generalised and localised infections can occur.
Cases of CMV infection, BK virus associated nephropathy, as well as cases of JC virus associated progressive multifocal leukoencephalopathy (PML), have been reported in patients treated with immunosuppressants, include tacrolimus.

Neoplasms benign, malignant and unspecified.

Reporting suspected adverse effects.

Reporting suspected adverse reactions after registration of the medicinal product is important. It allows continued monitoring of the benefit-risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions at www.tga.gov.au/reporting-problems.

4.9 Overdose

Symptoms.

Experience of overdosage is limited. Several cases of accidental overdosage have been reported; symptoms have included tremor, headache, nausea and vomiting, infections, urticaria, lethargy, increased blood urea nitrogen and elevated serum creatinine concentrations, and increase in alanine aminotransferase levels.
Early clinical experience (when initial induction doses were two to three times greater than those currently recommended) suggested that symptoms of overdosage may include glucose intolerance, renal, neurological and cardiac disorders, hyperkalaemia and hypertension. Over immunosuppression may increase risk of severe infections.
Liver function clearly influences all pre- and postoperative pharmacokinetic variables. Patients with failing liver grafts or those switched from other immunosuppressive therapy to Tacrolimus Sandoz or Tacrolimus XR Sandoz should be monitored carefully to avoid overdosage.

Treatment.

No specific antidote to tacrolimus therapy is available. If overdosage occurs, general supportive measures and symptomatic treatment should be conducted.
Based on the poor aqueous solubility and extensive erythrocyte and plasma protein binding, it is anticipated that Tacrolimus Sandoz or Tacrolimus XR Sandoz will not be dialysable. Data on haemoperfusion are not available. Activated charcoal may reduce absorption of the drug if given within one or two hours after ingestion. In patients who are not fully conscious or have impaired gag reflex, consideration should be given to administering activated charcoal via a nasogastric tube, once the airway is protected.
For information on the management of overdose, contact the Poisons Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

Tacrolimus is a macrolide lactone with potent in vitro and in vivo immunosuppressive activity. Studies suggest that tacrolimus inhibits the formation of cytotoxic lymphocytes which are regarded as being primarily responsible for graft rejection. Tacrolimus suppresses T cell activation and T helper cell dependent B cell proliferation, as well as the formation of lymphokines such as interleukins-2 and 3 and gamma-interferon and the expression of the interleukin-2 receptor. At the molecular level, the effects of tacrolimus appear to be mediated by binding to a cytosolic protein (FKBP) which is responsible for the intracellular accumulation of the compound. A complex of tacrolimus-FKBP-12, calcium, calmodulin and calcineurin is formed and the phosphatase activity of calcineurin inhibited.
Studies in animals and humans have shown that tacrolimus is able to prevent and treat graft rejection following transplantation of the liver, kidney and other solid organs.

Clinical trials.

Tacrolimus Sandoz - immediate release capsule.

Liver.

The efficacy and safety of a tacrolimus based immunosuppressive regimen following orthotopic liver transplantation was assessed in two prospective, randomised, nonblinded multicentre trials. The active control groups were treated with a ciclosporin based regimen. In a European trial, patients received a tacrolimus steroid based regimen (n = 264) or a ciclosporin/ azathioprine/ steroid (with or without antilymphocyte globulin) based regimen (n = 265).
Equivalent graft survival (77.5 versus 72.69%) and patient survival (82.9 versus 77.5%) was seen. Significant reductions were seen in the tacrolimus treated patients for incidence of acute rejection (40.5 versus 49.8%), refractory acute rejection (0.8 versus 5.3%) and chronic rejection (1.5 versus 5.3%). In an American trial, patients received a tacrolimus steroid regimen (n = 263) or a ciclosporin (mainly triple therapy) based regimen (n = 266). Equivalent graft survival (82 versus 79%) and patient survival (88 versus 88%) rates were observed. Tacrolimus was associated with significant reductions in the incidence of acute rejection (68 versus 76%), steroid resistant rejection (19 versus 36%) and refractory rejection (3 versus 15%).

Kidney.

Two randomised, multicentre nonblinded comparative trials were performed in cadaveric kidney transplantation. In an American trial, patients received a tacrolimus based (n = 205) or ciclosporin based (n = 207) regimen. All patients also received maintenance azathioprine and corticosteroids and an induction course of an antilymphocyte antibody preparation. Equivalent graft survival (91.2 versus 87.9%) and patient survival (95.6 versus 96.6%) was seen for the tacrolimus and ciclosporin treated patients, respectively. A significantly reduced one year incidence rate of biopsy confirmed acute rejection (30.7 versus 46.4%), moderate to severe acute rejection (10.7 versus 26.6%) and use of antilymphocyte antibody preparation for treatment of rejection (10.7 versus 25.1%) was seen in the tacrolimus treated patients.
A European trial compared triple drug based immunosuppression with tacrolimus or ciclosporin centred regimens, with 303 and 145 patients randomised to the tacrolimus and ciclosporin arms respectively. Equivalent one year graft survival (82.5 versus 86.2%) and one year patient survival (93.0 versus 96.5%) rates were observed, but with significantly reduced one year acute rejection rate (32.3 versus 54.5%), rate of corticosteroid sensitive rejections (24.4 versus 42.1%) and rate of corticosteroid resistant rejections (10.2 versus 20.7%).

Heart.

Two open label, randomised, comparative studies evaluated the safety and efficacy of tacrolimus based and ciclosporin based immunosuppression in primary orthotopic heart transplantation. In a phase III study conducted in Europe, 314 patients received a regimen of antibody induction, corticosteroids and azathioprine in combination with tacrolimus or ciclosporin modified for 18 months. In a three-arm study conducted in the US, 331 patients received corticosteroids and tacrolimus plus sirolimus, tacrolimus plus mycophenolate mofetil (MMF) or ciclosporin modified plus MMF for one year.
In the European phase III study, patient/ graft survival at 18 months post-transplant was similar between treatment arms, 91.7% in the tacrolimus group and 89.2% in the ciclosporin group. In the US study, patient and graft survival at 12 months was similar with 93.5% survival in the tacrolimus plus MMF group and 86.1% survival in the ciclosporin modified plus MMF group. In the European study, the ciclosporin trough concentrations were above the predefined target range (i.e. 100 to 200 nanogram/mL) at day 122 and beyond in 32 to 68% of the patients in the ciclosporin treatment arm, whereas the tacrolimus trough concentrations were within the predefined target range (i.e. 5 to 15 nanogram/mL) in 74 to 86% of the patients in the tacrolimus treatment arm.
The US study contained a third arm of a combination regimen of sirolimus, 2 mg/day, and full dose tacrolimus; however, this regimen was associated with increased risk of wound healing complications, renal function impairment and insulin dependent post-transplant diabetes mellitus, and is not recommended in de novo heart transplant patients (see Section 4.4 Special Warnings and Precautions for Use).

Lung.

In a prospective, two centre, open label randomised trial, 74 lung transplant patients (aged 20 to 66 years old) were randomised to tacrolimus based (n = 37) and ciclosporin based (n = 37) immunosuppression. The drugs were given in combination with mycophenolate mofetil and corticosteroids. Tacrolimus was started immediately after transplantation as continuous intravenous infusion at a dose of 0.015 mg/kg/day and oral tacrolimus was administered at a dose of 0.1 to 0.3 mg/kg/day with subsequent dose adjustments to target trough levels of 12 to 15 nanogram/mL in the first month and 9 to 12 nanogram/mL thereafter. The six months and one year patient survival data was similar in both groups (89 versus 84% and 82 versus 71%, ciclosporin versus tacrolimus, respectively). Freedom from acute rejection was comparable at one year, 35% in the ciclosporin group and 46% in the tacrolimus group.
Another prospective, randomised, open label study included 66 patients on tacrolimus versus 67 patients on ciclosporin, aged 20 to 66 years old. The drugs were given in combination with azathioprine and corticosteroids. Tacrolimus was started six to eight hours after transplantation as continuous intravenous infusion at a dose of 0.025 mg/kg/day and oral tacrolimus was administered at a dose of 0.15 mg/kg/day with subsequent dose adjustments to target trough levels of 10 to 20 nanogram/mL. The one year patient survival was 83% in the tacrolimus group and 71% in the ciclosporin group, the two year survival rates were 76 and 66%, respectively. The differences between groups were not statistically significant. Freedom from acute rejection after at least 37 weeks follow-up was also comparable (14% in the tacrolimus group and 11.5% in the ciclosporin group).
A number of published, open, uncontrolled studies have examined the use of tacrolimus in lung transplant patients who have developed refractory acute rejection or bronchiolitis obliterans syndrome while receiving ciclosporin based immunosuppressive regimens. In these studies, conversion from ciclosporin to tacrolimus has been associated with improved clinical outcomes such as reduced frequency of further acute rejection episodes and stabilisation or improvement in declining FEV1 values.
Tacrolimus XR Sandoz - prolonged-release capsules. Three Phase III non-inferiority studies have been conducted, confirming the safety and efficacy of tacrolimus prolonged-release capsules is comparable to tacrolimus immediate release capsules in de novo kidney transplant patients aged 12 years and older (n = 638 and 667) and de novo liver transplant patients aged 18 years and older (n = 471). Patient survival and graft survival at 1 year post transplant ranged from 91% to 99%. In these studies tacrolimus was used in combination with corticosteroids (liver transplant), with corticosteroids and mycophenolate mofetil (kidney), or with corticosteroids, mycophenolate mofetil and basiliximab (kidney).
The results of all conversion studies demonstrate that conversion from tacrolimus immediate release capsules-based immunosuppression regimens to tacrolimus prolonged-release capsules-based immunosuppression regimens on 1:1 (mg:mg) basis has been performed in adult kidney, liver and heart transplant recipients without any increase in incidences of acute rejection, graft loss or effects on patient survival rates. Long-term following up of patients in the conversion studies (up to 2 years) confirm patient survival and graft survival with Tacrolimus prolonged-release capsules were consistent across all conversion studies, ranging from 97% to 100%.

5.2 Pharmacokinetic Properties

Absorption.

In humans, tacrolimus has been shown to be able to be absorbed throughout the gastrointestinal tract. Available tacrolimus is generally rapidly absorbed.
Following oral administration of tacrolimus immediate release capsules peak concentrations (Cmax) of tacrolimus in blood are achieved in approximately one to three hours. Tacrolimus with prolonged-release formulation resulted in an extended oral absorption profile with an average time to Cmax of approximately 2 hours. In some patients, tacrolimus appears to be continuously absorbed over a prolonged period yielding a relatively flat absorption profile. The mean oral bioavailability of tacrolimus immediate release is in the range of 20 to 25%.
After oral administration (0.30 mg/kg/day) to liver transplant patients, steady-state concentrations of tacrolimus immediate release were achieved within three days in the majority of patients.
In healthy subjects, tacrolimus immediate release 0.5 mg, 1 mg and 5 mg capsules have been shown to be bioequivalent, when administered as equivalent dose.
The rate and extent of absorption of tacrolimus is greatest under fasted conditions. The presence of food decreases both the rate and extent of absorption of tacrolimus, the effect being most pronounced after a high fat meal. The effect of a high carbohydrate meal is less pronounced.
In stable liver transplant patients, the oral bioavailability of tacrolimus immediate release was reduced when it was administered after a meal of moderate fat (34% of calories) content. Decreases in AUC (27%) and Cmax (50%), and an increase in tmax (173%) in whole blood were evident.
In a study of stable renal transplant patients who were administered tacrolimus immediate release immediately after a standard continental breakfast the effect on oral bioavailability was less pronounced. Decreases in AUC (2 to 12%) and Cmax (15 to 38%), and an increase in tmax (38 to 80%) in whole blood were evident.
Bile flow does not influence the absorption of tacrolimus immediate release.
A strong correlation exists between AUC and whole blood trough levels at steady state for tacrolimus immediate release and tacrolimus prolonged-release formulations. Monitoring of whole blood trough levels, therefore, provides a good estimate of systemic exposure.

Distribution.

In humans, the disposition of tacrolimus after intravenous infusion may be described as biphasic.
In the systemic circulation, tacrolimus binds strongly to erythrocytes resulting in an approximate 20:1 distribution ratio of whole blood/ plasma concentrations. In plasma, tacrolimus is highly bound (> 98.8%) to plasma proteins, mainly to serum albumin and alpha1-acid glycoprotein.
Tacrolimus is extensively distributed in the body. The steady-state volume of distribution based on plasma concentrations is approximately 1,300 L (healthy subjects). Corresponding data based on whole blood averaged 47.6 L.
Tacrolimus is a low clearance substance. In healthy subjects, the average total body clearance (TBC) estimated from whole blood concentrations was 2.25 L/hour. In adult liver, kidney and heart transplant patients, values of 4.1, 6.7 and 3.9 L/hour, respectively, have been observed. Paediatric liver transplant recipients have a TBC approximately twice that of adult liver transplant patients. Factors such as low haematocrit and protein levels, which result in an increase in the unbound fraction of tacrolimus, or corticosteroid induced increased metabolism are considered to be responsible for the higher clearance rates observed following transplantation.
The half-life of tacrolimus is long and variable. In healthy subjects, the mean half-life in whole blood is approximately 43 hours. In adult and paediatric liver transplant patients, it averaged 11.7 and 12.4 hours, respectively, compared with 15.6 hours in adult kidney transplant recipients. Increased clearance rates contribute to the shorter half-life observed in transplant recipients.

Metabolism.

Tacrolimus is widely metabolised in the liver, primarily by the cytochrome P450-3A4 (CYP3A4) and the cytochrome P450-3A5 (CYP3A5). Tacrolimus is also considerably metabolised in the intestinal wall. There are several metabolites identified. Only one of these has been shown in vitro to have immunosuppressive activity similar to that of tacrolimus. The other metabolites have only weak or no immunosuppressive activity. In systemic circulation only one of the inactive metabolites is present at low concentrations. Therefore, metabolites do not contribute to pharmacological activity of tacrolimus.

Excretion.

Following intravenous and oral administration of 14C-labelled tacrolimus, most of the radioactivity was eliminated in the faeces. Approximately 2% of the radioactivity was eliminated in the urine. Less than 1% of unchanged tacrolimus was detected in the urine and faeces, indicating that tacrolimus is almost completely metabolised prior to elimination: bile being the principal route of elimination.

Pharmacokinetics in special populations.

The pharmacokinetics of tacrolimus in special populations have not been studied in detail. See Section 4.2 Dose and Method of Administration, Dose adjustments in special populations.
Following oral administration of Tacrolimus Sandoz to healthy subjects under fasting conditions, a mean peak plasma concentration (Cmax) of tacrolimus of approximately 3.3 nanogram/mL was achieved within approximately 1.25 hours (Tmax) for tacrolimus 0.5 mg capsules and a mean Cmax of tacrolimus of approximately 44 nanogram/mL was achieved within approximately 1.75 hours for tacrolimus 5 mg capsules.

5.3 Preclinical Safety Data

Genotoxicity.

No evidence of genotoxicity was seen in a series of assays for gene mutations and clastogenicity. Tacrolimus did not cause unscheduled DNA synthesis in rodent hepatocytes but high concentrations of tacrolimus have been reported to increase the frequency of sister chromatid exchanges in human lymphocytes in vitro.

Carcinogenicity.

Tacrolimus did not show any tumorigenic effects in long-term carcinogenicity studies using the mouse and rat. The maximum dose tested in the rat resulted in a blood exposure less than, and a plasma exposure 1.4 times, the exposure achieved after the maximum recommended clinical dose, 0.3 mg/kg, based on area under the curve (AUC). In mice the maximum dose was 0.8 times the recommended clinical dose based on body surface area.
Patients receiving long-term immunosuppressive therapy are at an increased risk of developing lymphomas and other malignancies (see Section 4.4 Special Warnings and Precautions for Use, Malignancies).
