What is Mupirocin?

Mupirocin is a powerful antibiotic ointment, derived from the bacterium Pseudomonas fluorescens. It is primarily used to treat superficial skin infections caused by certain bacteria. Its unique mechanism targets protein synthesis pathways within bacterial cells, making it a valuable tool in combating resistant strains of bacteria.

• Marketed under the brand names like Bactroban and Centany.
• Developed in the late 1980s, it quickly became a staple in fighting skin infections.

How Does Mupirocin Ointment Work?

This topical antibiotic inhibits bacterial protein synthesis, effectively killing the bacteria responsible for skin infections. Unlike other antibiotics, Mupirocin specifically targets the bacterial enzyme isoleucyl-tRNA synthetase, which is essential for protein synthesis.

• Works best on gram-positive bacteria like Staphylococcus and Streptococcus species.
• Particularly useful in treating resistant strains, preventing their spread and reducing symptoms rapidly.
