Asymptomatic Trichomoniasis. Metronidazole tablets are indicated in the treatment of asymptomatic  T. vaginalis infection in females when the organism is associated with endocervicitis, cervicitis, or cervical erosion. Since there is evidence that presence of the trichomonad can interfere with accurate assessment of abnormal cytological smears, additional smears should be performed after eradication of the parasite. Treatment of Asymptomatic Sexual Partners. T. vaginalis infection is a venereal disease. Therefore, asymptomatic sexual partners of treated patients should be treated simultaneously if the organism has been found to be present, in order to prevent reinfection of the partner.

CLINICAL PHARMACOLOGY
ABSORPTION
Disposition of metronidazole in the body is similar for both oral and
intravenous dosage
forms. Following oral administration, metronidazole is well absorbed,
with peak plasma
concentrations occurring between one and two hours after
administration.
Plasma concentrations of metronidazole are proportional to the
administered dose. Oral
administration of 250 mg, 500 mg, or 2,000 mg produced peak plasma
concentrations
of 6 mcg/mL, 12 mcg/mL, and 40 mcg/mL, respectively. Studies reveal no
significant
bioavailability differences between males and females; however,
because of weight
differences, the resulting plasma levels in males are generally lower.
DISTRIBUTION
Metronidazole is the major component appearing in the plasma, with
lesser quantities of
metabolites also being present. Less than 20% of the circulating
metronidazole is bound
to plasma proteins. Metronidazole appears in cerebrospinal fluid,
saliva, and breast milk
