    Abstract:
    Amebiasis caused by Entamoeba histolytica may be considered the most aggressive parasitic disease affecting human intestine, causing acute amoebic colitis and extra-intestinal diseases of high morbidity and mortality. 5-nitroimidazoles are the drugs of choice. In this multicenter, open and random clinical trial, the efficacy and tolerability of secnidazole suspension in a single oral dose of 1ml/kg was compared with 0.5ml/kg doses of tinidazole suspension given for 2 consecutive days to 303 Entamoeba histolytica-positive children aged 2 to 13. Patients with extra-intestinal complications were excluded from the study. Clinical and parasitological follow-up using the Faust and Kato-Katz method were carried out 7, 14, and 21 days after treatment. Clinical improvement/cure was observed in 93% of the patients in the secnidazole group and 91% in the tinidazole group. Parasitological success was reported for 77% and 63% of the secnidazole and tinidazole patients, respectively, showing a significant statistical difference between the two groups (p=0.007). Both drugs were well tolerated, and the adverse effects reported were mild, consisting mainly of digestive disturbances. This comparative study showed that a single oral dose of 1ml/kg of secnidazole produced a significantly higher parasitological cure rate than 2 doses of tinidazole. Secnidazole is a safe and effective drug for the treatment of uncomplicated intestinal amebiasis.
