Ornidazole: a new antiprotozoal compound for treatment of Trichomonas vaginalis infection.

Abstract
A new anti-protozoal compound, ornidazole, a derivative of nitroimidazole, was given in a single 2 g dose to 20 women with T. vaginalis infection. All the women were cured, but they suffered some side-effects. Plasma levels of ornidazole reached a peak 5-8 times higher than minimum inhibitory concentrations and exceeded this level for at least 36 h. It is therefore possible that a smaller dose might have had an adequate trichomonicidal effect and fewer side-effects. Further studies are in progress.
