A Bioequivalence Study of Oseltamivir From Oseltamivir 75 mg Caps (Pharmacare PLC, Palestine) and Tamiflu® 75 mg Caps (Hoffmann-La Roche, Switzerland)

Comparative Open-label,Randomized, Fasting, Single Dose, Two-way Crossover Bioequivalence Study of Oseltamivir From Oseltamivir 75 mg Caps (Pharmacare PLC, Palestine) and Tamiflu® 75 mg Caps (Hoffmann-La Roche, Switzerland)

Comparative randomized, single dose, two-way crossover open-label study to determine the bioequivalence of Oseltamivir from Oseltamivir 75 mg capsules (Pharmacare PLC, Palestine) and Tamiflu® 75 mg capsules (Hoffmann-La Roche, Switzerland under license Gilead Sciences ,California ,USA after a single oral dose administration of each to healthy adults under fasting conditions.

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: Oseltamivir; Drug: Tamiflu®

Detailed Description

Primary Pharmacokinetic Parameters: Cmax, Area under cover (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.
