[Tribendimidine enteric coated tablet in treatment of 1,292 cases with intestinal nematode infection--a phase IV clinical trial].

Abstract

OBJECTIVE:

To further evaluate the efficacy and safety of tribendimidine in treatment of adult patients with intestinal nematode infections.

METHODS:

An open and multi-center clinical trial was conducted in the provinces of Hainan, Sichuan and Guizhou. A total of 1,292 infected cases aged 15-70 years were enrolled in the study. Modified Kato-Katz method was used to diagnose the cases with intestinal nematode infections and assess the efficacy 3-4 weeks post treatment. Patients with Ascaris lumbricoides infection were treated orally with tribendimidine enteric coated tablets at a single dose of 300 mg, while in the patients with Ancylostoma duodenale, mixed A. duodenale and A. lumbricoides, or with other helminth infections, a single dose of 400 mg was administered.

RESULTS:

The cure rate and effective rate of the patients with Ancylostoma infection were 88.4% (1,009/1,141) and 99.1% (1,131/1,141), respectively, while in patients with A. lumbricoides infection, they were 95.0% (419/441) and 99.8% (440/441), respectively. The cure rate of tribendimidine enteric coated tablet given to patients with Trichuris trichiura infection at a single dose of 400 mg was 76.8% (109/142). The adverse effect induced by tribendimidine was light and transient with a rate of 3.3% (42/1,292). No apparent impact was seen on blood and urine routine examinations, hepatic and renal functions as well as ECG examination.

CONCLUSION:

It is further confirmed that under the used dosage for expanding treatment in larger sample of patients with various ages and infected with Ancylostoma duodenale, A. lumbricoides and other helminths, tribendimidine enteric coated tablet is safe with satisfactory efficacy.
