For the treatment of initial episodes of uncomplicated urinary tract infections due to susceptible strains of the following organisms: Escherichia coli , Proteus mirabilis , Klebsiella pneumoniae , Enterobacter species, and coagulase-negative Staphylococcus species, including S. saprophyticus .

ingredients: anhydrous lactose,
colloidal silicon dioxide, magnesium stearate, sodium lauryl sulfate,
sodium starch glycolate and
stearic acid.
CLINICAL PHARMACOLOGY
Trimethoprim is rapidly absorbed following oral administration. It
exists in the blood as unbound,
protein-bound, and metabolized forms. Ten to twenty percent of
trimethoprim is metabolized, primarily
in the liver; the remainder is excreted unchanged in the urine. The
principal metabolites of trimethoprim
are the 1- and 3-oxides and the 3 - and 4 -hydroxy derivatives. The
free form is considered to be the
therapeutically active form. Approximately 44% of trimethoprim is
bound to plasma proteins.
Mean peak serum concentrations of approximately 1 mcg/mL occur 1 to 4
hours after oral administration
of a single 100 mg dose. A single 200 mg dose will result in serum
levels approximately twice as high.
The half-life of trimethoprim ranges from 8 to 10 hours. However,
patients with severely impaired
renal function exhibit an increase in the half-life of trimethoprim,
which requires either dosage regimen
adjustment or not using the drug in such patients (see DOSAGEAND
ADMINISTRATION). During a
13 week study of trimethoprim administered at a daily dos
