Alternative drugs against Trichomonas vaginalis

ABSTRACT

To investigate the effect of drugs other than metronidazole, 3 non- pregnant women infected with Trichomonas vaginalis were treated with doxycycline, 2x200 mg/ day for 1 week. Another 3 women were treated with praziquantel, single dose, 40 mg/ kg body weight. No therapeutic effect was detected for either drug. In vitro, oxytetracycline led to death of T. vaginalis at a concentration of 15 mg in 0.5 mL medium. Extract of Myrtus communis caused death of T. vaginalis at pH 4.65, but failed to do so at pH 6.00. Extract of Eucalyptus comaldensis [50 mg in 0.1 mL medium] at pH 5.35 caused death of T. vaginalis after 24 hours
