Bioequivalence Evaluation of Losartan and Cozaar® formulations in healthy volunteers

Protocol summary

Study aim
bioequivalence evaluation of losartan and cozaar® formulations in healthy volunteers
Design
A randomized, two-treatment, two-period, cross over study
Settings and conduct
26 healthy subjects are enrolled. The study is single-blind. Following an overnight fast of at least 10 hours, the drug product is administered. In each treatment period, under supervision of study investigators, a single dose of 50 mg of Losartan is administered orally with 240 ml of water to subjects. No food is allowed for at least 4 hours post-dose. Water is allowed as desired except for one hour before and after drug administration. For the measurement of pharmacokinetic parameters, 5 ml blood samples are taken before (0 min) and at 0.33, 0.66, 1, 1.5, 2, 2.5, 3, 3.5, 4, 5, 6, 8, 10 and 24 hours after administration. The subjects spend approximately 11 hours at the study location during each treatment phase, starting 1 hour before dosing until 10 hours afterwards. The subjects show up for a post-study visit 24 after the dosing.

Randomization (investigator's opinion)
Randomized
Randomization description
Simple randomization administrating of test or reference product for each subject is determined according to the randomization schedule. The randomization schedule is prepared according to volunteer's allocated number. Each subject is identified by a number from 1 to 24 according to their entrance to volunteers' list in screening day. Randomly, Subjects with odd numbers receive the test drug and the subjects with even number receive the reference drug.
Blinding (investigator's opinion)
Single blinded
Blinding description
Volunteers are blind in this study. The volunteers, according to the predetermined random table that is available to the researcher, are in one of the groups receiving the test or reference drug. Volunteers are aware that they are receiving the test drug (Iranian) and the reference drug (approved drug), but they do not know in which study period they will receive the test and reference drug.
