Amlodipine-Benazepril 10mg-20mg Capsules in Healthy Subjects Under Fed Conditions

Randomized, 2-Way, Crossover, Bioequivalence Study of Amlodipine-Benazepril 10mg-20mg Capsules and Lotrel® Administered as 1 x 10 mg-20 mg Capsule in Healthy Subjects Under Fed Conditions.

The objective of this study is to compare the rate and extent of absorption if amlodipine-benzazepril 10 mg-20 mg capsules (test) versus Lotrel® (reference),administered as 1 x 10 mg- 20 mg capsule under fed conditions.
