title: Treatment failure in Trichomonas vaginalis infections in females. I. Concentrations of metronidazole in plasma and vaginal content during normal and high dosage.
abstract: Concurrent estimation by high pressure liquid chromatography (HPLC) of the concentrations of metronidazole in plasma and vaginal content in 12 patients with infections due to Trichomonas vaginalis who did not respond to normal and high-dose treatment has shown that the two levels are closely related to each other and to the dose. Individual idiosyncrasies in absorption of drug from the gut lumen or in its transfer into the vaginal content are unlikely to be the cause of treatment failure.
