Bioequivalence Study of Montelukast From Asmakast 5mg Chewable Tab.(Sandoz, Egypt) & Singulair 5mg Chewable Tab.(Merck)

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: Asmakast; Drug: Singulair

• Registration Number: NCT02479854
• Lead Sponsor: Genuine Research Center, Egypt

Brief Summary

Comparative randomized, single dose, two-way crossover open-label study To investigate the bioequivalence of Montelukast from 5 mg chewable tablets(Sandoz, Egypt) and Singulair5 mg chewable tablets(Merck \& Co. Inc. ), after a single oral dose administration of each to healthy adults under fasting conditions,

Detailed Description

19 blood samples will be drawn in each period. The total volume of blood will not exceed 200 ml throughout the whole study.0.00 (pre-dose), 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 2.00,2.50, 3.00,3.50, 4.00, 4.50, 5.00, 6.00, 8.00, 10.00, 12.00, and 24.00 hours postdose , 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.
