Triclabendazole is designated chemically as benzimidazole derivative, 6-chloro-5-(2, 3-dichlorophenoxy)-2-(methylthio)-1H-benzimidazole (triclabendazole). The molecular formula for triclabendazole is C 14 H 9 Cl 3 N 2 OS and the molecular weight is 359.65 g/mol.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Triclabendazole is an anthelmintic against Fasciola species [see Microbiology (12.4)] . 12.2 Pharmacodynamics Triclabendazole exposure-response relationships and the time course of pharmacodynamics response are unknown. Cardiac Electrophysiology Dose-dependent prolongation in the QTc interval was observed with EGATEN in a randomized, partially blinded, placebo- and moxifloxacin-controlled, 4-period cross-over study in healthy subjects. The largest placebo-corrected mean increase in QTc was 9.2 msec (upper limit of confidence interval (UCI): 12.2 msec) following oral administration of 10 mg/kg EGATEN twice daily (at the recommended dose), and the largest placebo-corrected mean increase in QTc was 21.7 msec (UCI: 24.

2 DOSAGE AND ADMINISTRATION The recommended dose of EGATEN is 2 doses of 10 mg/kg given 12 hours apart in patients 6 years of age and older. The 250 mg tablets are functionally scored and divisible into two equal halves of 125 mg. If the dosage cannot be adjusted exactly, round the dose upwards. Take EGATEN orally with food. EGATEN tablets can be swallowed whole or divided in half and taken with water or crushed and administered with applesauce. The crushed tablet mixed with applesauce is stable for up to 4 hours.

Interactions
- 7 DRUG INTERACTIONS CYP2C19 Substrates : Re-check the plasma concentration of concomitantly administered CYP2C19 substrates after cessation of EGATEN therapy, if the plasma concentrations of the CYP2C19 substrates are elevated during administration of EGATEN. ( 7.1 ) 7.1 Effect of EGATEN on CYP2C19 Substrates No specific clinical drug interaction studies have been conducted for triclabendazole. However, in vitro data suggest the potential for increased plasma concentrations of CYP2C19 substrates with concomitant use of triclabendazole [see Clinical Pharmacology (12.3)] .
