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

Study Overview
=================
Brief Summary
-----------------
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.
