To reduce the development of drug-resistant bacteria and maintain the effectiveness of trimethoprim tablets, USP and other antibacterial drugs, trimethoprim tablets, USP should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. 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 . Cultures and susceptibility tests should be performed to determine the susceptibility of the bacteria to trimethoprim. Therapy may be initiated prior to obtaining the

DESCRIPTION
Trimethoprim is a synthetic antibacterial available in tablet form for
oral administration.
Each scored white tablet contains 100 mg trimethoprim.
Trimethoprim is
5-[(3,4,5-trimethoxyphenyl)methyl]-2,4-pyrimidinediamine. It is a
white
to light yellow, odorless, bitter compound with a molecular weight of
290.32 and the
molecular formula C

N O . The structural formula is:
INACTIVE INGREDIENTS
Colloidal silicon dioxide, dibasic calcium phosphate dihydrate,
magnesium stearate,
microcrystalline cellulose, pregelatinized starch, and sodium starch
glycolate.
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 1.0 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 DOSAGE AND ADMINISTRATION). During a 13
