For the full list of excipients, see Section 6.1 List of Excipients.
3 Pharmaceutical Form
Powder for injection.
Sterile, pyrogen-free ivory white powder for reconstitution with water for injections. It is freely soluble in water and on reconstitution gives a clear solution.
4.1 Therapeutic Indications
Teicoplanin is indicated for the treatment of the following serious infections due to Staphylococci or Streptococci, which cannot be treated satisfactorily with less toxic agents, including β-lactam antibiotics: bone - osteomyelitis; joints - septic arthritis; blood - non-cardiac bacteraemia, septicaemia.
4.2 Dose and Method of Administration
Note.
Special instructions apply for reconstitution. See below.
The reconstituted teicoplanin injection should be administered intravenously or intramuscularly. Intravenous dosing may be by slow injection over 5 minutes or by infusion over 30 minutes. Maintenance dosage is once daily; however, initially a loading dose regimen of three doses at 12-hourly intervals is recommended, for rapid attainment of steady-state plasma levels.
The dose is to be adjusted on bodyweight whatever the weight of the patient.
An intramuscular injection of teicoplanin should not exceed 3 mL (400 mg) at a single site. Teicoplanin should not be administered by intraventricular route, due to risk of seizure.
Adults.
Septicaemia/ bacteraemia, acute or chronic osteomyelitis.
Treatment should be started with 6-12 mg/kg by the I.V. route every 12 hours for 3 doses then the daily maintenance dose should be 6 mg/kg.
Septic arthritis.
Patients with septic arthritis should receive 12 mg/kg, intravenously, every 12 hours for 3 doses then a daily maintenance dose of 12 mg/kg.
Elderly patients.
As for adults. If renal function is impaired, the instructions for impaired renal function should be followed.
While the total duration of therapy is determined by the type and severity of infection and by the clinical response of the patient, the following periods are often appropriate.
Uncomplicated bacteraemia.
2-4 weeks.
Septic arthritis or osteomyelitis.
3-6 weeks.
Patients with renal impairment.
For patients with impaired renal function, reduction of dosage is not required until the fourth day of teicoplanin treatment. Trough plasma teicoplanin concentrations should be monitored periodically after the first week of therapy and the dosage adjusted to prevent trough concentrations exceeding 30 microgram/mL in patients with septic arthritis or 15 microgram/mL in other cases.
From the fourth day of treatment. In mild renal insufficiency.
Creatinine clearance between 40 and 60 mL/min, teicoplanin dose should be halved, either by administering the initial unit dose every two days, or by administering half of this dose once a day.
In severe renal insufficiency.
Creatinine clearance less than 40 mL/min, and in haemodialysed patients, teicoplanin dose should be one third of the normal either by administering the initial unit dose every third day, or by administering one third of this dose once a day. Teicoplanin is not removed by dialysis.
Method of administration.
Preparation of injection. Note.
The powder should be reconstituted strictly in accordance with the instructions below. Errors in reconstitution may result in the formation of a stable foam and delivery of smaller doses.
The entire contents of the accompanying diluent water ampoule should be added slowly down the side wall of the vial of teicoplanin. The vial should be rolled gently between the palms until the powder is completely dissolved, taking care to avoid foam formation. Do not shake. If the solution does become foamy, allow to stand for 15 minutes for the foam to subside. Withdraw the entire contents from the vial slowly into a syringe, trying to recover most of the solution by placing the needle in the central part of the stopper.
To reduce microbiological hazard, use as soon as practicable after reconstitution/preparation. If storage is necessary, hold at 2-8°C for not more than 24 hours. Refrigerate, do not freeze. Protect from light. When storing reconstituted solution do not store in a syringe.
The reconstituted solution contains for a 400 mg vial: 400 mg/3.0 mL of teicoplanin.
Dilution of reconstituted solution. The reconstituted solution may be injected directly, or alternatively diluted with any of the following diluents.
0.9% Sodium chloride solution.
Compound sodium lactate solution.
To reduce microbiological hazard, use as soon as practicable after reconstitution. If storage is necessary, hold at 2-8°C for not more than 24 hours.
5% Glucose solution.
0.18% Sodium chloride and 4% glucose solution.
Solutions containing the above diluents (which contain glucose) should be stored at 2-8°C and should be used within 24 hours; solutions kept longer than 24 hours should be discarded.
As a matter of good pharmaceutical practice, solutions for intravenous infusion should be used immediately after admixing.
The product is for single use in one patient only. Discard any residue.4.3 Contraindications
Teicoplanin is contraindicated in patients with known hypersensitivity to the drug.
4.4 Special Warnings and Precautions for Use
Hypersensitivity reactions and anaphylaxis.
Serious, life-threatening hypersensitivity reactions, sometimes fatal, have been reported with teicoplanin (e.g. anaphylactic shock). If an allergic reaction to teicoplanin occurs, treatment should be discontinued immediately and appropriate emergency measures should be initiated.
Hypersensitivity to vancomycin.
Teicoplanin should be administered with caution in patients known to be hypersensitive to vancomycin since cross-hypersensitivity reactions, including fatal anaphylactic shock, may occur. However, a history of the "red man syndrome" that can occur with vancomycin is not a contraindication to teicoplanin.
Infusion related reactions.
"Red man syndrome" (a complex of symptoms including pruritus, urticarial, erythema, angioneurotic oedema, tachycardia, hypotension, dyspnoea), has been rarely observed (even at the first dose). Stopping or slowing the infusion may result in cessation of these reactions. Infusion related reactions can be limited if the daily dose is not given via bolus injection but infused over a 30-minute period.
Severe cutaneous adverse reactions (SCARs).
Life-threatening and fatal cutaneous reactions, including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported with the use of teicoplanin. Acute generalised exanthematous pustulosis (AGEP) has also been reported. Patients should be informed about the signs and symptoms of serious skin manifestations and monitored closely. If symptoms or signs of SJS, or TEN, DRESS or AGEP (e.g. progressive skin rash often with blisters or mucosal lesion or pustular rash, or any other sign of skin hypersensitivity) are present, teicoplanin treatment should be discontinued immediately.
Nephrotoxicity.
Nephrotoxicity and renal failure have been reported in patients treated with teicoplanin (see Section 4.8 Adverse Effects (Undesirable Effects)). Patients with renal insufficiency, or with risk factors for development of nephrotoxicity, patients receiving the high loading dose regimen of teicoplanin, and/or patients receiving teicoplanin in conjunction with or sequentially with other medicinal products with known nephrotoxic potential (e.g. aminoglycosides, colistin, amphotericin B, ciclosporin, cisplatin, furosemide and ethacrynic acid) should be carefully monitored.
Ototoxicity.
Hearing impairment has been reported with use of teicoplanin (see Section 4.8 Adverse Effects (Undesirable Effects)). Periodic auditory function tests are advised especially in cases of prolonged treatment, patients with renal insufficiency and/or patients receiving teicoplanin in conjunction with or sequentially with other medicinal products with known nephrotoxic and/or neurotoxic/ototoxic potential (e.g. aminoglycosides, colistin, amphotericin B, ciclosporin, cisplatin, furosemide and ethacrynic acid). These patients should be carefully monitored and the benefit of teicoplanin evaluated if hearing deteriorates.
Hepatic toxicity.
Hepatic toxicities have been reported with use of teicoplanin (see Section 4.8 Adverse Effects (Undesirable Effects)). Periodic liver function tests are recommended for prolonged treatment.
Haematologic toxicity.
Haematologic toxicities have been reported with the use of teicoplanin (see Section 4.8 Adverse Effects (Undesirable Effects)). Periodic haematological studies are advised during prolonged treatment.
Loading dose regimen.
Safety data show increased rates of nephrotoxicity when high teicoplanin loading doses such as 12 mg/kg body weight twice a day are administered (see Section 4.8 Adverse Effects (Undesirable Effects)). For patients given high loading dose regimens, blood creatinine values should be closely monitored for nephrotoxicity in addition to haematological examinations.
Intraventricular use.
Teicoplanin should not be administered by intraventricular route, due to the risk of seizure.
Superinfection.
The use of teicoplanin may result in overgrowth of non-susceptible organisms. Repeated evaluation of the patient's condition is essential. If new infections due to bacteria or fungi appear during treatment, appropriate measures should be taken.
The safety and efficacy of teicoplanin by the intrathecal route has not been studied.
Use in hepatic impairment.
No data available.
Use in renal impairment.
See Section 4.2 Dose and Method of Administration, Patients with renal impairment; Section 4.4 Special Warnings and Precautions for Use, Loading dose regimen, Ototoxicity, Nephrotoxicity.
Use in the elderly.
See Section 4.2 Dose and Method of Administration, Elderly patients.
Paediatric use.
No data available.
Effects on laboratory tests.
No data available.4.5 Interactions with Other Medicines and Other Forms of Interactions
Due to the potential for increased adverse effects, teicoplanin should be administered with caution in patients receiving concurrent nephrotoxic or ototoxic drugs, such as aminoglycosides, amphotericin B (amphotericin), ciclosporin and furosemide (frusemide).
4.6 Fertility, Pregnancy and Lactation
Effects on fertility.
No data available.
Category B3
Reproductive studies in rats and rabbits with subcutaneous doses up to 200 mg/kg/day and 15 mg/kg/day respectively did not reveal teratogenic effects. Teicoplanin was associated with an increase in the number of stillborn pups when rats were treated with subcutaneous doses ≥ 100 mg/kg/day. Pup weight was reduced at all doses tested (SC doses ≥ 10 mg/kg/day). It is not known if teicoplanin is excreted in breast milk during lactation.
Teicoplanin should not be used during confirmed or presumed pregnancy unless the potential benefits outweigh possible risks.
Teicoplanin should not be used during lactation unless the potential benefits outweigh possible risks.4.7 Effects on Ability to Drive and Use Machines
Teicoplanin can cause dizziness and headache. The ability to drive or operate machinery may be affected. Patients experiencing these undesirable effects should not drive or operate machinery.
4.8 Adverse Effects (Undesirable Effects)
In an open clinical trial involving patients with bone or joint infections, teicoplanin was associated with adverse reactions in 32% of the patients. However, treatment was discontinued because of adverse reactions in 17% of patients only. A clear cause-effect relationship was not established in these patients. The most frequent adverse reactions were fever, rashes, nausea, vomiting, rigors, pruritus and diarrhoea.
The following adverse effects have been reported.
Local reactions.
Pain, phlebitis, redness, abscess, thrombophlebitis.
Hypersensitivity.
Skin rash, erythema, pruritus, rigor, fever, bronchospasm, anaphylaxis, urticaria, angioedema, DRESS syndrome (drug reaction with eosinophilia and systemic symptoms), toxic epidermal necrolysis, erythema multiforme including Stevens-Johnson syndrome and rare reports of exfoliative dermatitis, acute generalised exanthematous pustulosis (see Section 4.4 Special Warnings and Precautions for Use, Severe cutaneous adverse reactions (SCARs)).
Hepatic.
Increased transaminases and/or alkaline phosphatase.
Haematologic.
Eosinophilia, thrombocytopenia, leucopenia, neutropenia, rare cases of reversible agranulocytosis, and pancytopenia.
Renal and urinary disorders.
Including rise in serum creatinine, blood urea, renal failure. Based on literature reports, the estimated rate of nephrotoxicity in patients receiving low loading dose regimen of average 6 mg/kg twice a day, followed by a maintenance dose of average 6 mg/kg once daily, is around 2%. In an observational post-authorisation safety study which enrolled 300 patients with a mean age of 63 years (treated for bone and joint infection, endocarditis or other severe infections) who received the high loading dose regimen of 12 mg/kg twice a day (receiving 5 loading doses as a median) followed by a maintenance dose of 12 mg/kg once daily, the observed rate of confirmed nephrotoxicity was 11.0% (95% CI = [7.4%; 15.5%]) over the first 10 days. The cumulative rate of nephrotoxicity from the start of treatment up to 60 days after the last dose was 20.6% (95% CI = [16.0%; 25.8%]). In patients receiving more than 5 high loading doses of 12 mg/kg twice a day, followed by a maintenance dose of 12 mg/kg once daily, the observed cumulative rate of nephrotoxicity from the start of treatment up to 60 days after the last administration was 27% (95% CI = [20.7%; 35.3%]).
Gastrointestinal.
Nausea or vomiting, diarrhoea.
Nervous system.
Dizziness, headache, seizures with intraventricular use.
Auditory.
Hearing loss, tinnitus, vertigo, other vestibular disorders.
Infections and infestations.
Superinfection (overgrowth of non-susceptible organisms).
In addition, infusion-related events, such as erythema or flushing of the upper body, have been rarely reported. These events occurred without a history of previous teicoplanin exposure and did not recur on re-exposure when the infusion rate was slowed and/or the concentration was decreased. These events were not specific to any concentration or rate of infusion.
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 (Australia).4.9 Overdose
In an observational post-authorisation safety study, patients receiving more than 5 high loading doses of 12 mg/kg twice a day, followed by a maintenance dose of 12 mg/kg once daily, had an observed cumulative rate of nephrotoxicity from the start of treatment up to 60 days after the last administration of 27% (95% CI = [20.7%; 35.3%]).
Cases of excessive doses administered in error to paediatric patients have been reported. In one report, agitation occurred in a 29 day-old newborn given 400 mg I.V. (95 mg/kg). In the other cases, there were no symptoms or laboratory abnormalities associated with teicoplanin.
Treatment of overdosage should be symptomatic. Teicoplanin is not removed by haemodialysis or peritoneal dialysis.

5 Pharmacological Properties
5.1 Pharmacodynamic Properties
Pharmacotherapeutic group: anti-infectives for systemic use, glycopeptide antibacterials, ATC code: J01XA02.
Mechanism of action.
Microbiology.
Teicoplanin is bactericidal or bacteriostatic on growing populations of susceptible Gram positive organisms; depending on the sensitivity of the organism and antibiotic concentration. Teicoplanin inhibits the growth of susceptible organisms by interfering with cell-wall biosynthesis at a different site from that affected by β-lactams. Teicoplanin is therefore effective against staphylococci (including those resistant to methicillin and other β-lactam antibiotics) and Streptococci.
Some cross-resistance is observed between teicoplanin and the glycopeptide vancomycin.
Teicoplanin has shown no cross-resistance to β-lactam antibiotics, macrolides, aminoglycosides, tetracycline, rifampicin or chloramphenicol.
Clinical trials.
No data available.
5.2 Pharmacokinetic Properties
Absorption.
Following intramuscular injection bioavailability is 100%; average peak plasma levels of 7.1 microgram/mL are achieved in 3-4 hours following a dose of 3 mg/kg.
Distribution.
In man, the plasma level profile after intravenous administration indicates a biphasic distribution (with a rapid distribution phase having a half-life of about 0.3 hours, followed by a more prolonged distribution phase having a half-life of 3 hours). At the end of the distribution phase, plasma levels and the subsequent time-concentration curves, are identical following intramuscular or intravenous administration of 3 mg/kg dose.
The apparent volume of distribution at steady state is similar to total body water, i.e. 0.6 L/kg.
Approximately 90-95% of teicoplanin is bound to plasma proteins. Teicoplanin penetrates into blister exudates and bone where it achieves peak concentrations comparable to those in serum after intramuscular injection. Peak levels in joint fluid are approximately 60% of peak serum concentrations. Teicoplanin penetrates very poorly into cerebrospinal fluid (CSF) and red blood cells.
Metabolism.
Metabolic transformation is minor, about 3%.
Excretion.
The elimination half-life is 70-100 hours. About 80% of administered drug is excreted in the urine over a 16 day collection period.
5.3 Preclinical Safety Data
Genotoxicity.
Teicoplanin was negative in assays evaluating the potential to cause gene mutations, but assays to evaluate the potential to cause chromosome damage have not been performed.
Carcinogenicity.
Long-term studies in animals to evaluate the carcinogenic potential of teicoplanin have not been performed.6 Pharmaceutical Particulars
