  Purpose
  • Objective:

    • The objective of this study was to assess the relative bioavailability of two formulations of immediate release amlodipine 10 mg under fasted conditions, in healthy subjects.
  • Study Design:

    • This was an open-label, single-dose, 2-treatment, 2-period, randomized, crossover study.Twenty-two healthy subjects were enrolled. Subjects who successfully completed the screening process checked into the research center the night before first dose. Subjects who continued to meet inclusion/exclusion criteria the morning of dose were assigned a subject number, based on the order in which they successfully completed the screening process and procedures as outlined in the study protocol. Subjects were randomly assigned to a treatment sequence and received two separate single-dose administrations of study medication, one treatment per period,according to the randomization schedule. Dosing days were separated by a washout period of at least 14 days. Subjects received each of the treatments listed below during the two treatment periods following an overnight fast of at least 10 hours: amlodipine by Torrent Pharmaceuticals Ltd. and Norvasc by Pfizer, Inc.
