Bioequivalence Study of PMR Compared to Cilostazol IR Tablets in Healthy Volunteers

An Open-Label, Randomized, Two-Treatment, Two-Sequence, Four-Period, Fully Replicated Crossover Bioequivalence Study of Once Daily PMR Compared to Twice Daily Cilostazol IR Tablets in Healthy Volunteers

The study is designed to evaluate the bioequivalence and the within-subject variability between the test formulation of extended-release tablet of cilostazol (PMR) administered once daily and the reference formulation of immediate-release tablet of cilostazol (Cilostazol) administered twice-daily in normal healthy male and female subjects under fasting conditions.

Are using one or more of the following acceptable methods of contraception: surgical sterilization (e.g. bilateral tubal ligation, hysterectomy), hormonal contraception (e.g. implantable, injectable, vaginal, patch, and oral), and double-barrier methods. Reliable contraception should be maintained throughout the study and for seven (7) days after study discontinuation.
• Known or suspected hypersensitivity to any ingredient of the study drug(s).
• Donated blood or lost more than 150 mL of blood within three (3) months prior to randomization or plans to donate blood or plasma within four (4) weeks after completion of the study.
