Also known as pseudomonic acid, 9-{(E)-4-[(2S,3R,4R,5S)-3,4-dihydroxy-5-({(2S,3S)-3- [(2S,3S)-3-hydroxybutan-2-yl]oxiran-2-yl}methyl)oxan-2-yl]-3-methylbut-2-enoyl}oxynonanoic acid, pseudomonic acid A, C26H44O9, BRL-4910A

Mupirocin, sold under the brand name Bactroban among others, is a topical antibiotic useful against superficial skin infections such as impetigo or folliculitis. It may also be used to get rid of methicillin-resistant S. aureus (MRSA) when present in the nose without symptoms. Out of concerns of developing resistance, use for greater than ten days is not recommended. It is used as a cream or ointment applied to the skin.

Mupirocin, sold under the brand name Bactroban among others, is a topical antibiotic useful against superficial skin infections such as impetigo or folliculitis. It may also be used to get rid of methicillin-resistant S. aureus (MRSA) when present in the nose without symptoms. Out of concerns of developing resistance, use for greater than ten days is not recommended. It is used as a cream or ointment applied to the skin.

Common side effects include itchiness and rash at the site of application, headache, and nausea. Long-term use may result in increased growth of fungi. Use during pregnancy and breastfeeding appears to be safe. Mupirocin is chemically a carboxylic acid. It works by blocking a bacterium's ability to make protein, which usually results in bacterial death.
