Dithiazanine, 3-ethyl-2-[5-(3-ethyl-2-benzothiazolinylidene)-l, 3- pentadienyl] benzothiazolium iodide, is an old effective broad-spectrum human anthelmintic. In proper dosage, this polyvermicide is therapeutic for trichuriasis, strongyloidiasis, ascariasis, and enterobiasis. The drug also has significant anthelmintic activity against human hookworm, Necator americanus. It fulfills a need for an effective therapeutic for trichuriasis and strongyloidiasis. Dithiazanine is useful for the treatment of patients with either single or multiple intestinal helminth infections. It is effective for mass therapy for trichuriasis. Nowdays Dithiazanine is used only as a veterinary anthelmintic for dogs. It has being proved to be a highly toxic chemical, with a lethal dose for humans of about 4–16 mg/kg by oral ingestion.

Sample Use Guides

In Vivo Use Guide

Trichuriasis in 164 patients was treated with doses of 200 mg. thrice daily; this dosage, continued for five days, cured 97% of the patients. Ascariasis was treated in 42 persons with up to 600 mg. daily in divided doses. There was a 97% reduction in the egg-count of these patients, and 28 of them showed complete elimination of the infection. Strongyloidiasis was eliminated in 16 out of a group of 18 patients treated for 5 to 21 days. Enterobiasis was treated in 35 boys under conditions showing that 100 mg. of dithiazanine thrice daily for five days sufficed for cure in all cases.

Route of Administration: Oral

In Vitro Use Guide

Moderate in vitro activity against adult worms of Clororchis sinensis was observed in the concentrations of 1.0 and 0.1 ug/ml of gentian dithiazanine.
