Brief summary: Comparative randomized, single dose, two-way crossover open-label study to determine the bioequivalence of Amlodipine / valsartan from Amlodipine/Valsartan 10/160 film coated tablets (Pharmacare, Palestine) and Exforge 10/160 film coated tablets (Novartis Pharma, USA).

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.
