A Bioequivalence Study of Rabeprazole From Idiazole 20mg DR Tabs (GSK, Egypt) and PARIET 20 mg DR Tabs (JANSSEN, EGYPT)
- Registration Number
- NCT02477306
- Lead Sponsor
- Genuine Research Center, Egypt
- Brief Summary
Comparative randomized, single dose, two-way crossover open-label study to determine the bioequivalence of Rabeprazole from Idiazole 20mg DR tabs (GSK, Egypt)and PARIET 20 mg DR tabs (JANSSEN, EGYPT) after a single oral dose administration of each to healthy adults under fasting conditions.
- Detailed Description
Primary Pharmacokinetic Parameters: Cmax, AUC0→t and AUC0→∞ Secondary Pharmacokinetic Parameters: Ke, tmax and t1/2e. ANOVA using 5% significance level for transformed (with the 90% confidence intervals) and untransformed data of Cmax, AUC0→t and AUC0→∞ and for untransformed data of Ke, tmax and t1/2e. The confidence intervals of logarithmically transformed Test/Reference ratios for Cmax, AUC0→t and AUC0→∞ to be within 80.00-125.00%.
A comprehensive final report will be issued upon the completion of the study.

Group Intervention Description Study group Idiazole 20mg DR tabs 60 subjects will receive a single oral dose of idiazole 20mg DR tabs under fasting condition in one period. And the subjects will receive a single dose of PARIET 20 mg DR tabs under fasting condition in the second period. A 7 days washout interval is in between the 2 periods Study group PARIET 20 mg DR tabs 60 subjects will receive a single oral dose of idiazole 20mg DR tabs under fasting condition in one period. And the subjects will receive a single dose of PARIET 20 mg DR tabs under fasting condition in the second period. A 7 days washout interval is in between the 2 periods
- Primary Outcome Measures
Name Time Method Maximal measured plasma concentration (Cmax) Up to 14 hours post dose in each treatment period Serial blood samples for determination of study drug will be collected pre-dose and at 0.00, 0.50, 1.00, 1.50, 2.00, 2.33, 2.67, 3.00, 3.33, 3.67, 4.00, 4.33, 4.67, 5.0, 5.33, 5.67, 6.00, 8.00, 12.0 and 14.0 hours post dose, relative to dosing on Day 1 in each cross over period.
Area under the plasma concentration-time curve from time zero to the last measurable concentration (t) (AUC [0 to t]) Up to 14 hours post dose in each treatment period (AUC \[0 to t\]) will be calculated by the linear trapezoidal method.
Area Under the plasma concentration-time curve from time zero to infinity (AUC [0 to infinity]) Up to 14 hours post dose in each treatment period AUC (0 to infinity) will be calculated as the sum of the AUC (0 to t) plus the ratio of the last measurable plasma concentration to the elimination rate constant
- Secondary Outcome Measures
Name Time Method Time of the maximum plasma concentration (tmax) Up to 14 hours post dose in each treatment period If the Tmax occurs at more than time point, then tmax will be considered for the first occurrence.
Terminal half life (t1/2e) Up to 14 hours post dose in each treatment period The elimination or terminal half-life will be calculated as 0.693/ Ke
Apparent first-order elimination or terminal rate constant (K¬e) Up to 14 hours post dose in each treatment period K¬e will be calculated from a semi-log plot of the plasma concentration versus time curve. The parameter will be calculated by linear least-squares regression analysis using the last three (or more) non-zero plasma concentrations
