Overview
Brief Summary
Comparative randomized, single dose, two-way crossover open-label study to determine the bioequivalence of Montelukast fromAsmakast10 mg tablets (Man. by Minapharm Egypt for Novartis Pharma Egypt S.A.E (Sandoz), Egypt) and Singulair10 mg tablets (Produced by Global Napi Pharmaceuticals, Egypt under license from: Merck & Co. Inc., USA) 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 post dose. 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 & Interventions

reference drug (Singulair) 1 tablet contains 10 mg Montelukast
Intervention: Singulair
Outcomes
Primary Outcomes
measurable concentration (t) (AUC [0 to t])
Time Frame: 24 hours
(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])
Time Frame: 24 hours
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
Maximal measured plasma concentration (Cmax)
Time Frame: 24 hours
Serial blood samples for determination of study drug will be collected pre-dose and at 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
Secondary Outcomes
- Time of the maximum plasma concentration (tmax)measurable concentration (t) (AUC [0 to t])(24 hours)
- Apparent first-order elimination or terminal rate constant (K¬e)(24 hours)
- Terminal half life (t1/2e)(24 hours)
