Bivacyn is indicated for
Bacterial skin infections
Precautions and warnings
Neuromuscular disorders, hearing impaired, extensive skin damage. Avoid application in large quantities and prolonged use. Do not use if tympanic membrane is perforated. Pregnancy and lactation. Liver and renal impairment.
Hypersensitivity reactions. Possibility of ototoxicity
- nephrotoxicity if used in large quantities or on large areas for prolonged use.
Bacitracin Zinc: Increased risk of nephrotoxicity when used with other nephrotoxic drugs. May enhance the action of neuromuscular-blocking agents.
Neomycin Sulphate: Additive nephrotoxic and neurotoxic effect w/ other aminoglycosides (e.g. paromomycin), bacitracin, cisplatin, vancomycin, amphotericin B, polymyxin B, colistin and viomycin. Enhanced toxicity w/ potent diuretics (e.g. ethacrynic acid, furosemide). May impair the absorption of other drugs (e.g. phenoxymethylpenicillin, digoxin, methotrexate and some vit). May reduce the efficacy of OCs. May enhance the effect of acarbose. May enhance the effect of non-depolarising muscle relaxants. May antagonise the parasympathomimetic effect of neostigmine and pyridostigmine. May increase the risk of hypocalcaemia in patients receiving bisphosphonates. May alter INR when given w/ anticoagulants. May inactivate oral typhoid vaccine.
Hypersensitivity to aminoglycosides. Pre-existing nerve deafness. Neonates and infants
Mode of actions
Neomycin, an aminoglyoside with antimicrobial spectrum similar to gentamicin, binds to the 30S subunits of the bacterial ribosome, inhibiting protein synthesis and thereby disrupting DNA synthesis. It is active against many gram-negative aerobes and against some strains of staphylococci. Bacitracin, on the other hand, inhibits bacterial cell wall synthesis and is active against many gram-positive bacteria (e.g. staphylococci, streptococci, corynebacteria and clostridia) and some gram-negative species (e.g. Neisseria and Haemophilus influenzae). They are often found in combinations in topical preparations as broad spectrum antibacterial agents.
Dosage & Administration
Adult: Topical: Cream: Apply 3 times/day.
Powder: Apply 2-4 times/day.
Pregnancy & Lactation
Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
