This is an open-label, randomized, single dose, two-sequence, two-periods crossover study, separated by 7 days washout interval from the first Study Drug Administration. This study is conducted to determine the bioequivalence of Rabeprazole from IDIAZOLE 20mg Delayed-Release (DR) tablets (tabs) and PARIET 20 mg DR tabs after a single oral dose administration of each to healthy adults fed under conditions.
In Period 1, subjects will be randomized to either Idiazole 20mg DR tabs or PARIET 20 mg DR tabs. Following a washout of at least 7 days, subjects will be crossed over in Period 2 to receive the treatment that they did not receive in Period 1.

During this study, 74 participants were screened. One participant was excluded for significant variation in laboratory results at screening and three participants voluntarily withdrew before entering in to period 1. Hence, 70 participants were enrolled and randomized in study, and all 70 participants completed both periods of the study.
Bioequivalence of rabeprazole from Idiazole 20 milligram (mg) tablets and Pariet 20 mg tablets was investigated after single oral dose administration to healthy participants under fed conditions. This study was conducted from 22 March 2014 to 30 March 2014.
