drug
Quick Summary
Bacitracin is a polypeptide antibiotic derived from Bacillus subtilis or B. licheniformis. It is primarily used topically to combat infections caused by gram-positive bacteria. Due to its potential toxicity to kidney cells, its internal use is restricted. Instead, bacitracin is commonly found in ointments and eye drops for treating skin, eye, and ear infections. It functions by inhibiting the synthesis of bacterial cell walls.12
