Neomycin Sulfate + Bacitracin Zinc

This is indicated in the treatment of topical bacterial infections. This is particularly effective in atopic, contact stasis and infections, eczematoid dermatitis, neurodermatitis, eczema, anogenital pruritus. It may also be useful as an adjunct in certain pyodermas, such as impetigo, during specific systemic antibiotic therapy for these infections.

Ophthalmic and Topical antibacterial products

Bacitracin 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.

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.

Ointment: Before use, the area for application should be cleaned gently. Derbis such as pus or crusts should be removed from the affected area. Apply two to three times daily to the affected skin area.

Patients considering self-medication with a topical anti-infective for deep or puncture wounds, animal bites, or serious burns should be advised to first consult a physician.

Neomycin Sulphate: Additive nephrotoxic and neurotoxic effect with other aminoglycosides, bacitracin, cisplatin, vancomycin, amphotericin B, polymyxin B, colistin and viomycin. Enhanced toxicity with potent diuretics. May impair the absorption of other drugs. 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.
