DESCRIPTION
Fosfomycin tromethamine granules for oral solution contains fosfomycin
tromethamine,
a synthetic, broad spectrum, bactericidal antibiotic for oral
administration. It is available
as a single-dose sachet which contains white granules consisting of
5.631 grams of
fosfomycin tromethamine (equivalent to 3 grams of fosfomycin), and the
following
inactive ingredients: mandarin flavor, orange flavor, saccharin, and
sucrose. The
contents of the sachet must be dissolved in water. Fosfomycin
tromethamine, a
phosphonic acid derivative, is available as (1 _R_,2
_S_)-(1,2-epoxypropyl)phosphonic acid,
compound with 2-amino-2-(hydroxymethyl)-1,3-propanediol (1:1). It is a

CLINICAL PHARMACOLOGY
ABSORPTION: Fosfomycin tromethamine is rapidly absorbed following oral
administration
and converted to the free acid, fosfomycin. Absolute oral
bioavailability under fasting
conditions is 37%. After a single 3-gram dose of fosfomycin
tromethamine, the mean (±
1 SD) maximum serum concentration (C
) achieved was 26.1 (± 9.1) mcg/mL within
2 hours. The oral bioavailability of fosfomycin is reduced to 30%
under fed conditions.
Following a single 3-gram oral dose of fosfomycin tromethamine with a
high-fat meal,
the mean C
achieved was 17.6 (± 4.4) mcg/mL within 4 hours.
Cimetidine does not affect the pharmacokinetics of fosfomycin when
coadministered
with fosfomycin tromethamine. Metoclopramide lowers the serum
concentrations and
urinary excretion of fosfomycin when coadministered with fosfomycin
tromethamine.
(See PRECAUTIONS, DRUG INTERACTIONS.)
DISTRIBUTION: The mean apparent steady-state volume of distribution (V
) is 136.1
(±44.1) L following oral administration of fosfomycin tromethamine.
Fosfomycin is not
bound to plasma proteins.
