A Bioequivalence Study of Rabeprazole From Idiazole 20mg DR Tabs (GSK, Egypt) and PARIET 20 mg DR Tabs (JANSSEN, EGYPT)

Comparative Open-label,Randomized, Fasting, Single Dose, Two-way Crossover Bioequivalence Study of Rabeprazole From Idiazole 20mg DR Tabs (GSK, Egypt) and PARIET 20 mg DR Tabs (JANSSEN, EGYPT)

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.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: Idiazole 20mg DR tabs; Drug: PARIET 20 mg DR tabs

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.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Study group; 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	Drug: Idiazole 20mg DR tabs; Delayed release tablets containing 20 mg of rabeprazole; Drug: PARIET 20 mg DR tabs; Orally administered, delayed-release, enteric-coated tablets containing 20 mg of rabeprazole sodium.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximal measured plasma concentration (Cmax)	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.	Up to 14 hours post dose in each treatment period
Area under the plasma concentration-time curve from time zero to the last measurable concentration (t) (AUC [0 to t])	(AUC [0 to t]) will be calculated by the linear trapezoidal method.	Up to 14 hours post dose in each treatment period
Area Under the plasma concentration-time curve from time zero to infinity (AUC [0 to infinity])	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	Up to 14 hours post dose in each treatment period

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time of the maximum plasma concentration (tmax)	If the Tmax occurs at more than time point, then tmax will be considered for the first occurrence.	Up to 14 hours post dose in each treatment period
Apparent first-order elimination or terminal rate constant (K¬e)	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	Up to 14 hours post dose in each treatment period
Terminal half life (t1/2e)	The elimination or terminal half-life will be calculated as 0.693/ Ke	Up to 14 hours post dose in each treatment period
