A Bioequivalence Study of Montelukast From Asmakast 10mg Tabs (Sandoz, Egypt) & Singulair 10mg Tabs (Merck)
Comparative Open-label,Randomized, Fasting, Single Dose, Two-way Crossover Bioequivalence Study of Montelukast From Asmakast 10mg Tabs (Sandoz, Egypt) & Singulair® 10mg Tabs (Merck & Co, Egypt) to Healthy Adult Volunteers
Study Overview
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
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
|
24 hours
|
measurable concentration (t) (AUC [0 to t])
Time Frame: 24 hours
|
(AUC [0 to t]) will be calculated by the linear trapezoidal method.
|
24 hours
|
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
|
24 hours
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time of the maximum plasma concentration (tmax)measurable concentration (t) (AUC [0 to t])
Time Frame: 24 hours
|
If the Tmax occurs at more than time point, then tmax will be considered for the first occurrence..
|
24 hours
|
Apparent first-order elimination or terminal rate constant (K¬e)
Time Frame: 24 hours
|
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
|
24 hours
|
Terminal half life (t1/2e)
Time Frame: 24 hours
|
The elimination or terminal half-life will be calculated as 0.693/ Ke
|
24 hours
