Trichomonal vaginitis. A 24-hr regimen of nimorazole compared with a 7-day regimen of metronidazole.

A 24-hr regimen of nimorazole (1 g. orally at 12-hrly intervals for three doses) was compared with metronidazole (200 mg. three times daily for 7 days) in the treatment of trichomonal vaginitis. The two treatment schedules were given to alternate patients, pregnant women being excluded. One hundred cases were treated on each schedule; roughly one-fifth of the patients in each group defaulted. There were no observed failures with either schedule. The reasons for these exceptionally good results are discussed.
