Aminitrozole (Tritheon), also known as nithiamide, for some years has been successfully used in medicated feeds in the prevention of enterohepatitis (blackhead disease) in turkeys. Besides, this drug was studied in human for the treatment of trichomoniasis. Sixteen patients with vaginal trichomoniasis have been treated with Tritheon tablets. As a result, in all the thirteen patients followed, T. vaginitis was recovered after therapy. No untoward side-effects were noted, but the clinical results were uniformly bad.
