is (_E_)-(2_S_,3_R_,4_R_,5_S_)-5-
[(2_S_,3_S_,4_S_,5_S_)-2,3-Epoxy-5-hydroxy-4-methylhexyl]tetrahydro-3,4-dihydroxy-β-methyl-2_H_-pyran-2-
crotonic acid, ester with 9-hydroxynonanoic acid. The molecular

CLINICAL PHARMACOLOGY
Application of
C-labeled mupirocin ointment to the lower arm of normal male subjects
followed by
occlusion for 24 hours showed no measurable systemic absorption (<1.1
nanogram mupirocin per
milliliter of whole blood). Measurable radioactivity was present in
the stratum corneum of these
subjects 72 hours after application.
Following intravenous or oral administration, mupirocin is rapidly
metabolized. The principal
metabolite, monic acid, is eliminated by renal excretion, and
demonstrates no antibacterial activity. In a
study conducted in 7 healthy adult male subjects, the elimination
half-life after intravenous
administration of mupirocin was 20 to 40 minutes for mupirocin and 30
to 80 minutes for monic acid.
The pharmacokinetics of mupirocin has not been studied in individuals
with renal insufficiency.
MICROBIOLOGY -
Mupirocin is an antibacterial agent produced by fermentation using the
organism _Pseudomonas_
_fluorescens_. It is active against a wide range of gram-positive
bacteria including methicillin-resistant
_Staphylococcus aureus_ (MRSA). It is also active against certain
gram-negative bacteria. Mupirocin
inhibits bacterial protein synthesis by reversibly and specifically
binding to bacterial isoleucyl transfer-
RNA synthetase. Due to this unique mode of action, mupirocin
demonstrates no _in
