Bacitracin A
Bacitracin A is an antibiotic and medicated skin ointment used to treat minor cuts, scrapes, and burns. It is most commonly found in a topical form, where it inhibits bacterial growth and prevents infections from forming. It is a polypeptide antibiotic made up of amino acids, and it is naturally found in certain bacteria, fungi, and soil organisms.
Uses For
Bacitracin A is used primarily to prevent infection arising from cuts, lacerations, abrasions, and burns. It is commonly used as an antiseptic when applied topically, although less common internal uses for the drug includes treatment of some eye, ear, and urinary tract infections in some cases. It also can be used as a ointment to help reduce redness and inflammation associated with certain skin conditions.
Mechanism of Action
Bacitracin A works by inhibiting the synthesis of peptidoglycans, which are essential components of bacterial cell walls. It does this by preventing the transpeptidation reaction that binds peptidoglycan together, ultimately hindering the growth of the bacterial cell wall and eventually killing the bacterial cells. The drug also sometimes works synergistically with other antibiotics that target different sites within the bacterial cell.
How Long Does it Take to Work?
