Bioderm Ointment, Cream

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.


This is used for furunculosis, impetigo, sycosis barbae, eczema, skin ulcer, infected wounds, infected burn wounds, strains of Staphylococci which are resistant to other antibiotics usually remain sensitive to Bacitracin.
