This is an open-label, randomized, single dose, two-sequence, two-period crossover study, separated by 7 days washout interval from the first study drug administration.
In this study, the bioavailability of Rabeprazole from Idiazole 20 milligram (mg) delayed release (DR) tablets and PARIET 20 mg DR tablets after a single oral dose administration of each to healthy adults under fasting conditions, will be investigated by determining the 90% confidence limits for the log-transformed ratio (Test product / Reference product) for the bioequivalence parameters. The influence of sequence, product and period effect will be tested by analysis of variance (ANOVA).
In this study a total of 60 subjects plus 1-4 additional subjects will be enrolled and split into two groups (Group A and B) of 30 each. For each subject, a total of 33 blood draws will be done and the volume of blood will not exceed 300 milliliters (mL) for the study.

Delayed release tablets containing 20 mg of rabeprazole
Orally administered, delayed-release, enteric-coated tablets containing 20 mg of rabeprazole sodium.
Time frame: Pre-dose (0.00) and 0.50, 1.00, 1.50, 2.00, 2.33, 2.66, 3.00, 3.33, 3.66, 4.00, 4.33, 4.66, 5.00, 5.33, 5.66, 6.00, 8.00, 12.00 and 14.00 h post-dose in each treatment period.
Plasma samples for pharmacokinetic (PK) analysis were drawn at indicated time points of each treatment period. Cmax was defined as maximal measured plasma concentration over the time span specified. Values were reported as Least Squares Geometric Means with respective Geometric Coefficient of Variation (% CV).
Time frame: Pre-dose (0.00) and 0.50, 1.00, 1.50, 2.00, 2.33, 2.66, 3.00, 3.33, 3.66, 4.00, 4.33, 4.66, 5.00, 5.33, 5.66, 6.00, 8.00, 12.00 and 14.00 h post-dose in each treatment period.
Plasma samples for PK analysis were drawn at indicated time points of each treatment period. AUC0-t was calculated by the linear trapezoidal method. AUC0-infinity was calculated as the sum of the AUC0-t plus the ratio of the last measurable plasma concentration to the elimination rate constant, where first-order elimination or terminal rate constant was calculated from a semi-log plot of the plasma concentration versus time curve. The parameter was calculated by linear least-squares regression analysis using the last three (or more) non-zero plasma concentrations. Values were reported as Least Squares Geometric Means with respective % CV.
Time frame: Pre-dose (0.00) and 0.50, 1.00, 1.50, 2.00, 2.33, 2.66, 3.00, 3.33, 3.66, 4.00, 4.33, 4.66, 5.00, 5.33, 5.66, 6.00, 8.00, 12.00 and 14.00 h post-dose in each treatment period.
Plasma samples for PK analysis were drawn at indicated time points of each treatment period. If the maximum value occurs at more than one point T-max was defined as the first time point with this value. The elimination or terminal half-life was calculated by dividing 0.693 (natural logarithm of 2) with b obtained as the slope of the linear regression of the logarithmically transformed plasma concentrations versus time in the terminal period of the plasma curve.
Time frame: Pre-dose (0.00) and 0.50, 1.00, 1.50, 2.00, 2.33, 2.66, 3.00, 3.33, 3.66, 4.00, 4.33, 4.66, 5.00, 5.33, 5.66, 6.00, 8.00, 12.00 and 14.00 h post-dose in each treatment period
Plasma samples for PK analysis were drawn at indicated time points of each treatment period. Apparent first-order elimination or terminal rate constant calculated from a semi-log plot of the plasma concentration versus time curve. The parameter was calculated by linear least-squares regression analysis using the last three (or more) non-zero plasma concentrations.
