Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using CERNEVIT I.V.

What is in this leaflet?

This leaflet answers some common questions about Cernevit Multivitamin powder for injection.

It does not contain all of the available information. All medicines have risks and benefit. Your doctor has weighed the risks of you using Cernevit against the benefit they expect it will have for you.

It does not take the place of talking to your doctor or pharmacist.

If you have any concerns about being administered this medicine, ask your doctor or pharmacist.

Keep this leaflet; you may need to read it again.

What Cernevit is used for?

This medicine belongs to the vitamins, mineral and other nutritional supplements group of medicines. It is a multivitamin preparation of both water and fat-soluble vitamins (without Vitamin K) stabilised with a mixture of solubilising agent. This medicine is used as a multivitamin supplement corresponding your daily needs and is given as an injection or infusion directly into the vein (intravenously).

Before you are given Cernevit

Cernevit should not be given to you if:

  • You have had an allergic reaction to any of the ingredients of Cernevit listed in the Ingredients section of this leaflet, especially thiamine (Vitamin B1) or soy/protein products. Some of the symptoms of an allergic reaction may include skin rash, peeling of the skin, itching or hives, swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing or shortness of breath.
  • You have an impairment with liver function. You are suffering from hyperparathyroidism due to abnormally elevated calcium levels in the blood.
  • The expiry date (EXP) printed on the pack has passed.

You must tell your doctor if:

  • You are allergic to thiamine (Vitamin B1), nicotinamide components of this product, any other medicines, foods, dyes, or preservatives.
  • You have any other health problems including:
    - Kidney disease
    - Active inflammatory bowel disease
    - You are currently receiving additional vitamins from any other sources, especially with Vitamin A, D and E
    - Liver disease
  • You are pregnant or intend to become pregnant, as it is not known whether Cernevit may cause harm to the foetus. Your doctor will discuss with you the risks and benefits of giving this product during pregnancy.
  • You are breast-feeding or wish to breast feed, as it is known that vitamins are excreted in breast milk. Your doctor will discuss with you the risks and benefits of giving Cernevit injection to a nursing mother.
  • You are taking prescription medicines, such as antiepileptic drugs; phenobarbitol, primidone and phenytoin (with brand name Dilantin). The effectiveness of the active component in antiepileptic drugs is affected by folic acid, one of the vitamins included in the Cernevit formulation. Several vitamins can decrease the effectiveness of antibiotics, such as bleomycin and the tetracycline family.
  • You are taking medications containing theophylline, tipranavir or vitamin K antagonists, such as warfarin.
  • You are taking any other medicines including any that you get without a prescription from your pharmacy, supermarket or health food stores, in particular for heart or blood pressure or levodopa for the treatment of Parkinson’s disease.

How is Cernevit given?

How much is given:

Your doctor will decide when and how much Cernevit will be given to you, which depends on your need and condition.

How is it given:

Your doctor will inject the medicine into you. Cernevit injection will be given to you as a slow injection after it has been mixed with drip solutions, directly into the vein (intravenously) by your doctor or trained nurse.

This medicine is for single use and for one person only. Any unused portion must be discarded and not used later, either for you or anyone else.

How long will it be given:

Your doctor will determine the duration of your treatment, which will depend on your need.

Case of overdose

The doctor or nurse giving you Cernevit has had experience in the use of this sort of medicine, so it is unlikely that you will be given an overdose. However, in case of an overdose, the Cernevit treatment will be discontinued and another treatment may be needed. You may experience some of the effects listed under “Side Effects” below.

Side Effects

As with any medicines, some side effects may occur. Allergic reactions have been known to occur following intravenous injection of Vitamin B1.

Always tell your doctor or nurse if you have any unexpected effects during or after receiving Cernevit and they worry you, including:

  • Swelling of the face, lips, mouth or throat, which may cause difficulty in swallowing.
  • Flushing, itching or burning of the skin, sneezing/hives or mild asthma-like attacks.
  • Yellowing of the skin and eyes, also called jaundice.
  • Breathing difficulties
  • Faster heart beat
  • Diarrhea

Storage Conditions

Cernevit should be stored below 25°C and protected from light and heat.

Do not freeze.

2 Qualitative and Quantitative Composition

Cernevit is a multivitamin preparation, lyophilised, sterile powder, for reconstitution in 5 mL of Water for Injections or other compatible parenteral fluids.
Content of lyophilisate in each vial (see Table 1).

Excipients.

Glycine 250 mg, Glycocholic acid 140 mg, Lecithin 112.5 mg, (Lecithin [Soybean] 112.5 mg), Sodium hydroxide 10% qs and/or, 1 M hydrochloric acid qs pH 5.9.
The active ingredients in Cernevit are water-soluble and fat-soluble vitamins, which are well characterised. The Glycine component is included in the formulation as an excipient in order to facilitate the reconstitution of the lyophilised product with Water for Injection.

3 Pharmaceutical Form

Cernevit is a sterile dosage form for intravenous injection or infusion containing nine water-soluble and three fat-soluble vitamins (vitamin K is not included in Cernevit), using mixed micelles (glycocholic acid and lecithin) as a solubilising agent. It is presented as a lyophilised, orange-yellow, sterile powder. That is to be reconstituted with 5 mL of water for injections or other parenteral fluids, (e.g. as 0.9% sodium chloride, 5% glucose or nutritional mixtures), prior to administration by parenteral route.

4 Clinical Particulars

4.1 Therapeutic Indications

Cernevit is indicated in adults and children over 11 years of age requiring parenteral multivitamins supplementation to correct or prevent vitamin deficiencies when oral administration is contraindicated, impossible or insufficient. This product does not contain vitamin K, which may be given separately if required.

4.2 Dose and Method of Administration

Dosage.

Adults and children over 11 years.

One vial per day reconstituted with water for injection (5 mL) or other compatible IV solutions (5 mL) as described under Administration and reconstitution.
If infused intravenously, Cernevit should be administered slowly. If injected intravenously, the injection must be administered slowly (over at least 10 minutes).
The patient's clinical status and vitamin levels should be monitored to ensure maintenance of adequate levels.
It should be taken into account that some vitamins, especially A, B2, and B6 are sensitive to ultraviolet light (e.g. direct or indirect sunlight). In addition, loss of vitamins A, B1, C, and E may increase with higher levels of oxygen in the solution. These factors should be considered if adequate vitamin levels are not achieved.

Administration and reconstitution.

Cernevit is a sterile preparation. Thus, aseptic procedure must be applied throughout the administration and reconstitution. The single dose vial of Cernevit is reconstituted by adding 5 mL of sterile water for injection or other intravenous fluids (0.9% sodium chloride injection or 5% glucose injection). Five millilitres (5 mL) of diluent should be added by means of sterile syringe into the vial and gently mixed to dissolve the lyophilised powder. Before transfer from the vial, Cernevit must be completely dissolved. Do not use product unless the reconstituted solution is clear and the original seal is intact. The entire volume of the resultant solution should then be administered by slow intravenous injection (at least over 10 minutes) or further diluted for intravenous infusion.
Mix the final solution thoroughly when Cernevit is used as an admixture in parenteral nutrition.
Any unused portion of reconstituted Cernevit should be discarded and should not be stored for subsequent admixing. Parenteral drug products should be inspected visually for particulate matter and abnormal discoloration prior to administration, whenever solution and container permit. Use of a final filter is recommended during administration of all parenteral nutrition solutions.
After reconstitution, Cernevit should be used immediately or stored at 2°C to 8°C for no more than 24 hours.

Incompatibilities.

Additives may be incompatible with parenteral nutrition containing Cernevit.
Do not add other medicinal products or substances without first confirming their compatibility and the stability of the resulting preparation.
If coadministration of drugs that are incompatible at the Y-site is necessary, administer via separate IV lines.
Vitamin A and thiamine in Cernevit may react with bisulfites in parenteral nutrition solutions (e.g. as a result of admixtures) leading to degradation of vitamin A and thiamine.
An increase in pH of a solution may increase the degradation of some vitamins. This should be considered when adding alkaline solutions to the admixture containing Cernevit.
Folic acid stability can be impaired with increased calcium concentrations in an admixture.
Numerous other incompatibilities between vitamins and other medicinal products, including certain antibiotics, and trace elements have been described.
See appropriate compatibility references and guidelines as needed.

4.3 Contraindications

Cernevit is contraindicated in patients with pre-existing hypervitaminosis or known hypersensitivity to Cernevit, to any of the active ingredients, or soy/ peanut protein products in particular patients with hypersensitivity to thiamine (vitamin B1). Thus, Cernevit should not be injected to patients with pre-existing intolerance to thiamine. Similarly, this product should not be administered to patients with impaired hepatic function.
Cernevit should not be administered to those suffering from hyperparathyroidism due to hypercalcaemic complications.

4.4 Special Warnings and Precautions for Use

Allergic reactions.

Anaphylactic reactions may occur in allergic subjects who are susceptible to thiamine (vitamin B1) and nicotinamide components of this product. Mild allergic reactions such as sneezing or mild asthma are warning signs that further injection may give rise to anaphylactic shock.
In some cases, the manifestations of a hypersensitivity reaction during intravenous administration of multivitamins may be rate related. The infusion or injection must be stopped immediately if signs or symptoms of a hypersensitivity reaction develop.
Cernevit contains soy derived lecithin. Cross-allergic reactions between soybean and peanut proteins have been observed.

Vitamin toxicity.

The patients's clinical status and blood vitamin concentrations should be monitored to avoid overdose and toxic effects, especially with vitamins A, D and E, and in particular in patients who receive additional vitamins from other sources or use other agents that increase the risk of vitamin toxicity.
Monitoring is particularly important in patients receiving long-term supplementation.
Daily vitamin requirements must be calculated in order to avoid overdose and toxic effects, in particular with fat soluble vitamins, such as vitamin A. Caution should be exercised when administering Cernevit to patients who may be receiving vitamin A from other sources.
The recommended dietary intakes (RDI) of vitamin A in pregnant and lactating women as recommended by the NHMRC is 2,500 IU (750 microgram retinol equivalents). Cernevit contains 3,500 IU vitamin A, administered by intravenous route, thus the use of this product in pregnant or lactating women is not recommended. Teratogenic effects have been observed in isolated cases with a dose vitamin A over 10,000 IU per day.
The risk for hypervitaminosis A and vitamin A toxicity (e.g. skin and bone abnormalities, diplopia, cirrhosis) is increased in, for example:
patients with protein malnutrition,
patients with renal impairment (even in the absence of vitamin A supplementation),
patients with small body size (e.g. paediatric patients), and
patients on chronic therapy.
Caution should be exercised when administering Cernevit to patients who may be receiving Vitamin A, D and E from other sources and those receiving long-term supplementation.

Refeeding syndrome.

Refeeding severely undernourished patients may result in refeeding syndrome that is characterised by the shift of potassium, phosphorus, and magnesium intracellularly as the patient becomes anabolic. Thiamine deficiency and fluid retention may also develop. Careful monitoring and slowly increasing nutrient intakes while avoiding overfeeding can prevent these complications.

Precipitates.

Pulmonary vascular precipitates have been reported in patients receiving parenteral nutrition. In some cases, fatal outcomes have occurred. Excessive addition of calcium and phosphate increases the risk of the formation of calcium phosphate precipitates. Precipitates have been reported even in the absence of phosphate salt in the solution. Precipitation distal to the in line filter and suspected precipitate formation in the bloodstream have also been reported.
In addition to inspection of the solution, the infusion set and catheter should also periodically be checked for precipitates.
If signs of pulmonary distress occur, the infusion should be stopped and medical evaluation initiated.

Intravenous bolus injection.

Following intravenous bolus injection, a moderate rise in SGPT transaminases has been noted in some patients with active inflammatory enterocolitis. The increased levels are rapidly reversible following the cessation of the treatment. It is recommended to monitor transaminase levels in patients of this type.

Vitamin K.

Cernevit does not contain Vitamin K. If the patient requires this vitamin, it should be administered separately.

General monitoring.

Clinical status and vitamin levels should be monitored in patients receiving parenteral multivitamins as the only source of vitamins for extended periods of time. It is particularly important to monitor for adequate supplementation of, for example:
Vitamin A in patients with pressure ulcers, wounds, burns, short bowel syndrome or cystic fibrosis;
Vitamin B1 in dialysis patients;
Vitamin B2 in cancer patients;
Vitamin B6 in patients with renal impairment;
Individual vitamins whose requirements may be increased due to interactions with other medicines (see Section 4.5 Interactions with Other Medicines and Other Forms of Interactions).
Deficiency of one or more vitamins must be corrected by specific supplementation.

Vitamin B12 deficiency.

Evaluation of vitamin B12 status is recommended before starting supplementation with Cernevit in patients at risk for vitamin B12 deficiency and/or when supplementation with Cernevit over several weeks is planned.
After several days of administration, both the individual amounts of cyanocobalamin (vitamin B12) and folic acid in Cernevit may be sufficient to result in an increase in red blood cell count, reticulocyte count, and haemoglobin values in some patients with vitamin B12 deficiency-associated megaloblastic anaemia. This may be masking an existing vitamin B12 deficiency. Effective treatment of vitamin B12 deficiency requires higher doses of cyanocobalamin than provided in Cernevit.
Folic acid supplementation in patients with vitamin B12 deficiency, who do not also receive vitamin B12, does not prevent the development or progression of neurologic manifestations associated with the vitamin B12 deficiency. It has been suggested that neurologic deterioration may even be accelerated.
When interpreting levels of vitamin B12, it should be taken into account that recent intake of vitamin B12 may result in normal levels despite a tissue deficiency.

Hepatic effects.

Monitoring of liver function parameters is recommended in patients receiving Cernevit. Close monitoring is recommended in patients with hepatic jaundice or other evidence of cholestasis.
In patients receiving Cernevit, instances of liver enzyme increases have been reported, including isolated alanine aminotransferase (ALT) increases in patients with inflammatory bowel disease.
In addition, increases in bile acid levels may occur in patients receiving Cernevit.
Hepatobiliary disorders including cholestasis, hepatic steatosis, fibrosis and cirrhosis, possibly leading to hepatic failure, as well as cholecystitis and cholelithiasis are known to develop in some patients on parenteral nutrition (including vitamin supplemented parenteral nutrition). The etiology of these disorders is thought to be multifactorial and may differ between patients. Patients developing abnormal laboratory parameters or other signs of hepatobiliary disorders should be assessed early by a clinician knowledgeable in liver diseases in order to identify possible causative and contributory factors, and possible therapeutic and prophylactic interventions.

Use in hepatic impairment.

See Section 4.3 Contraindications.

Use in renal impairment.

Patients with renal impairment may need individualised vitamin supplementation, depending on the degree of renal impairment and the presence of concomitant medical conditions. In patients with severe renal impairment, particular attention should be placed on maintaining adequate vitamin D status and preventing vitamin A toxicity, which may develop in such patients with low-dose vitamin A supplementation or even without supplementation.
Pyridoxine (vitamin B6) hypervitaminosis and toxicity (peripheral neuropathy, involuntary movements) have been reported in patients on chronic haemodialysis receiving intravenous multivitamins containing 4 mg pyridoxine administered three times a week.
Also in the case of impaired kidney function, fat-soluble vitamin levels should be carefully monitored.

Use in the elderly.

No data available.

Paediatric use.

No data available.

Effects on laboratory tests.

Depending on the reagents used, the presence of ascorbic acid in blood and urine may cause false high or low glucose readings in some urine and blood glucose testing systems, including test strips and handheld glucose meters. The technical information for any laboratory test should be consulted to determine the potential interference from vitamins.
Biotin may interfere with laboratory tests that are based on a biotin/streptavidin interaction including tests used in emergency situations. The interference may result in either falsely decreased or falsely increased test results, depending on the assay. The risk of interference is higher in children and patients with renal impairment and increases with higher doses.
When interpreting results of laboratory tests, possible biotin interference must be taken into consideration, especially if lack of coherence with the clinical presentation is observed (e.g. inaccurate thyroid test results mimicking Grave's disease in asymptomatic patients or falsely low troponin T test results in patients with myocardial infarction). Consult laboratory personnel for alternative tests in cases where biotin interference is suspected.

4.5 Interactions with Other Medicines and Other Forms of Interactions

In an in vitro study using human serum, therapeutic concentration of glycocholic acid increased the unbound fraction of drugs known to bind to α1-acid glycoprotein by 50-80%. It is not known whether this effect is clinically relevant if the amount of glycocholic acid contained in a standard Cernevit dose (as a component of the mixed micelles) is administered by slow intravenous injection, intramuscular injection, or infused over a longer period of time. Patients receiving drugs that bind to α1-acid glycoprotein should be closely monitored for increases in response to these drugs, e.g. propranolol, prazosin and quinidine.
The dosage of drugs known to be influenced by folic acid, for example phenytoin (Dilantin), must be carefully monitored. Folic acid may obscure pernicious anaemia. Folic acid may increase the metabolism of some antiepileptics, such as phenobarbital, phenytoin and primidone. Pyridoxine can reduce the effect of levodopa. Bleomycin can be inactivated by ascorbic acid and riboflavin. Several vitamins can decrease the effectiveness of antibiotics, such as tetracycline.
It has been reported that PVC bags and plastic tubing delivery system absorb fat soluble vitamins onto the plastic surface, in particular vitamin A in the form of pure vitamin A or vitamin A acetate, which are highly prone to this phenomenon. The use of vitamin A palmitate and 'mixed micelles' as solubilising agents in the formulation of Cernevit reduces the absorption of fat soluble vitamins onto plastic bag as a result of the high rate of vitamin A palmitate being trapped into the micelles cages. Using non-PVC bags may prevent this interaction. Some of the vitamins, especially A, D, pyridoxine and riboflavin are light sensitive. Thus, light protection is recommended during administration of an IV infusion admixture containing Cernevit, by wrapping the container with an adequate light barrier cover.
In addition, loss of vitamins A, B1, C, and E may increase with higher levels of oxygen in the solution. These factors should be considered if adequate vitamin levels are not achieved.
Interactions between specific vitamins in Cernevit and other agents should be managed accordingly. Such interactions include:
Agents that can cause pseudotumor cerebri (including certain tetracyclines): increased risk for pseudotumor cerebri by concomitant administration of Vitamin A.
Alcohol (chronic excessive consumption): increases the risk of vitamin A hepatotoxicity.
Anticonvulsants (phenytoin, fosphenytoin, phenobarbital, primidone): folic acid supplementation can decrease the anticonvulsant serum concentration and increase seizure risk.
Antiplatelet agents (e.g. aspirin): vitamin E can add to the inhibition of platelet function.
Aspirin (high dose therapy): can reduce folic acid levels by increasing urinary excretion.
Certain anticonvulsants (e.g. phenytoin, carbamazepine, phenobarbital, valproate): can cause folate, pyridoxine and vitamin D deficiencies.
Certain antiretroviral agents: decreased vitamin D levels have been associated with, e.g. efavirenz and zidovudine. Decreased formation of the active vitamin D metabolite has been associated with protease inhibitors.
Chloramphenicol: can inhibit the hematological response to vitamin B12 therapy.
Deferoxamine: increased risk of iron induced cardiac failure due to increased iron mobilization by supraphysiologic vitamin C supplementation. For specific precautions, see deferoxamine product information.
Ethionamide: can cause pyridoxine deficiency.
Fluoropyrimidines (5-fluorouracil, capecitabine, tegafur): increased cytotoxicity when combined with folic acid.
Folate antagonists, e.g. methotrexate, sulfasalazine, pyrimethamine, triamterene, trimethoprim, and high doses of tea catechins: block the conversion of folate to its active metabolites and reduce the effectiveness of supplementation.
Folate antimetabolites (methotrexate, raltitrexed): folic acid supplementation can decrease the antimetabolite effects.
Pyridoxine antagonists, including cycloserine, hydralazine, isoniazid, penicillamine, phenelzine: can cause pyridoxine deficiency.
Retinoids, including bexarotene: increase the risk of toxicity when used concomitantly with vitamin A.
Theophylline: can cause pyridoxine deficiency.
Tipranavir oral solution: contains 116 IU/mL of vitamin E, which is in excess of daily recommended intake.
Vitamin K antagonists (e.g. warfarin): enhanced anticoagulant effect by vitamin E.
Patients receiving Cernevit as well as drugs that bind to alpha1-acid glycoprotein (AAG) should be closely monitored for increases in response of these drugs e.g. propranolol, prazosin.
Some medications can interact with certain vitamins at doses markedly higher than those provided with Cernevit. This should be taken into consideration in patients receiving vitamins from multiple sources, and when applicable, patients should be monitored for such interactions and managed accordingly.

4.6 Fertility, Pregnancy and Lactation

Effects on fertility.

No fertility studies have been performed with Cernevit.
(Category D)
Animal reproduction studies have not been performed with Cernevit. However, embryofetal toxicity studies were carried out in rats and rabbits using heat degraded mixed micelles, a solubilising agent used in Cernevit. In rabbits, maternotoxic doses of heat degraded mixed micelles led to an increased abortion rate, but there were no adverse effects on the foetus.
Vitamin A is classified as category D in the Australian categorisation of risk of drug in pregnancy. The amount of vitamin A in this product is below the RDA adopted by the FDA (USA), but above that recommended by the NHMRC. This product has not been formally assessed in human pregnancy, therefore use of this product in pregnancy is not recommended. Teratogenic effects have been observed in isolated cases with doses of vitamin A over 10,000 IU/day.
It is not known if this drug is excreted in breast milk, but as many vitamins are, the use of this product in lactating women is not recommended.

4.7 Effects on Ability to Drive and Use Machines

The effects of this medicine on a person's ability to drive and use machines were not assessed as part of its registration.

4.8 Adverse Effects (Undesirable Effects)

Anaphylactic reactions have been reported following intravenous doses of thiamine. There have been reported very rare events of anaphylactic reaction following IV injection of Cernevit over 1-4 minutes. Giant urticaria has been very rarely reported, as well as rash. Transient rises in SGPT transaminases have been observed after bolus injection in patients with active inflammatory enterocolitis. Individuals susceptible to the effects of nicotinamide may experience flushing, itching or burning of the skin.

In some cases, the manifestations of a hypersensitivity reaction during intravenous administration of multivitamins may be rate related (see Section 4.4 Special Warnings and Precautions for Use).

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

There is little data concerning the overdosage of Cernevit.
Acute or chronic overdose of vitamins (in particular A, B6, D, and E) can cause symptomatic hypervitaminosis.
The risk of overdose is particularly high if a patient receives vitamins from multiple sources and overall supplementation of a vitamin does not match the patient's individual requirements, and in patients with increased susceptibility to hypervitaminosis.
The signs of overdose of Cernevit are mostly those resulting from administration of excessive doses of vitamin A.
Clinical signs of acute overdose of vitamin A (doses exceeding 150,000 IU): gastrointestinal disorders, headache, raised intracranial pressure, papilloedema, psychiatric disorders, irritability, or even convulsions, delayed generalised desquamation.
Clinical signs of chronic intoxication (prolonged vitamin A supplementation with supraphysiological doses in nondeficient subjects): raised intracranial pressure, cortical hyperostosis of long bones and premature epiphyseal fusion. The diagnosis is generally based on the presence of tender or painful subcutaneous swellings in the extremities of the limbs. X-rays demonstrate diaphyseal periosteal thickening of the ulna, fibula, clavicles and ribs.
Action to be taken in the event of acute or chronic overdose: stop administration of Cernevit, reduce calcium intake, increase diuresis and rehydrate. Hypercalcaemia occurs as a result of vitamin D hypervitaminosis. Symptoms of hypercalcaemia include nausea, vomiting, polyuria, anorexia, weakness, apathy, thirst and constipation. Chronic overdose can lead to vascular and organ calcification.
Chronic overdoses can lead to vascular and organ calcification as a result of hypercalcaemia. Treatment should consist of stopping all intake of calcium and vitamin D and rehydration.
In cases of suspected overdose, symptomatic and supportive therapy should be instituted as appropriate, and further administration of the product discontinued.
Given the doses of these vitamins contained in Cernevit, it is unlikely that, used as directed, toxicity would occur, however, care must be taken if patients are receiving any additional supplementation from other sources.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.1 Pharmacodynamic Properties

Mechanism of action.

A general mode of action of Cernevit is to provide a balanced physiological effect mediated by the water soluble and fat soluble vitamins in adults and children.
Composition and proportion of each vitamin correspond to the recommendations of the American Medical Association, Food and Drug Administration and Food and Nutrition Board in parenteral nutrition.

Clinical trials.

No data available.

5.2 Pharmacokinetic Properties

Absorption.

The mode of administration of Cernevit is by injectable route, thus the bioavailability of this product is considered 100% as it is directly provided into systemic circulation.

Metabolism.

Each vitamin has its specific function in regulating metabolic process in living cells. As Cernevit contains more than one active ingredient, it has multifactorial physiological effects. Some functions are performed by one vitamin, such as vitamin A, which is necessary for proper functioning of the retina and the integrity of epithelial cells. Insufficient retinol (Vitamin A) supplies for the formation of rhodopsin lead to a night blindness syndrome. Other fat-soluble vitamins (Vitamin D and E) are involved in different functions. That is, Vitamin E preserves the essential cell constituents by virtue of its anti-oxidant property, whilst Vitamin D exerts its physiological effect via a hormone-like mode of action on bone formation and mineral homeostasis.
Water-soluble vitamins act as co-enzymes, mainly in energy metabolism. The B-complex vitamins are necessary for conversion of carbohydrate, protein and fat into tissue and energy. That is, biotin and niacin function as a component of carboxylase enzymes in those metabolic reactions, whilst Vitamin C is involved in collagen formation and tissue repair.
Tetrahydrofolic acid, the co-enzyme form of the vitamin, serves as an acceptor and a donor of one carbon unit in amino acid and nucleotide metabolism.

Excretion.

Excess intake of water-soluble vitamins is excreted readily by the kidney in the urine by virtue of a high solubility of the parent and their metabolites in water, thereby accumulations rarely take place. Thus, toxicity is less often experienced with water-soluble vitamins than with fat-soluble vitamins.
An excess intake of fat-soluble vitamins, such as Vitamin A, may lead to a toxic effect because of its accumulation in the body. This is caused by a slow metabolism and excretion of this vitamin. More than 90% of Vitamin A body supply is stored in the liver and this reserve is usually sufficient for several months to a year. Thus, frequent replacement of Vitamin A is not needed, in contrast to water-soluble vitamins (Vitamin B-complex and Vitamin C), which require a continuous replacement due to their fast excretion from the body.

5.3 Preclinical Safety Data

Genotoxicity.

No mutagenicity studies have been performed with Cernevit. In a single test for mutagenicity in bacteria, heat-degraded mixed micelles, a solubilising agent in the product, were not mutagenic.

Carcinogenicity.

No carcinogenicity studies have been performed with Cernevit.
