Indications & Uses

Neobac is indicated for:

Pharmacology

Bacitracin stops bacteria from building their cell wall. It works against many gram-positive bacteria (for example staphylococci, streptococci, corynebacteria and Clostridia) and against some gram-negative species (for example Neisseria and Haemophilus influenzae). Because of this broad cover, it is often put together with other antibacterial agents in topical preparations.

Neomycin is an aminoglyoside, and its antimicrobial spectrum is similar to gentamicin. It binds to the 30S subunits of the bacterial ribosome and blocks protein synthesis, which in turn disrupts DNA synthesis. Neomycin is active against many gram negative aerobes and against some strains of staphylococci.

The skin ointment contains Neomycin, so it should not be used for otitis externa when the eardrum is perforated. There is a risk of ototoxicity. Patients thinking of treating deep wounds, puncture wounds, animal bites or serious burns on their own with a topical anti-infective should be advised to see a physician first. Patients using these preparations to prevent infection in minor skin injuries (for example cuts, scrapes and burns) should be advised to stop the preparation and consult a physician if the condition persists or worsens.
