DESCRIPTION
Each gram of Mupirocin Ointment USP, 2% contains 20 mg mupirocin in a
bland water miscible ointment
base (polyethylene glycol ointment, N.F.) consisting of polyethylene
glycol 400 and polyethylene
glycol 3350. Mupirocin is a naturally occurring antibiotic. The
chemical name 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-

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
trial 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
_Pseudomonasfluorescens_. Mupirocin inhibits bacterial protein
synthesis by reversibly and specifically
binding to bacterial isoleucyl transfer-RNA (tRNA) synthetase. Due to
this unique mode of action,
mupirocin does not demonstrate cross-resistance with other classes of
antimicrobial agents.
When mupirocin resistance occurs, it results from the production of a
modified isoleucyl-tRNA
