Mupirocin Ointment IP 2% w/w is a topical antibiotic used to treat bacterial skin infections such as impetigo, folliculitis, and infected minor wounds. It works by inhibiting bacterial protein synthesis through the selective blockade of isoleucyl-tRNA synthetase, making it effective against common pathogens like Staphylococcus aureus and Streptococcus pyogenes, including some resistant strains like MRSA. Applied 2–3 times daily, it helps reduce infection, inflammation, and promotes healing.
