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

An Open-Label, Randomized, Three-Treatment, Three-Way Crossover Pharmacokinetic Study of Once Daily PMR Compared to Twice Daily Cilostazol IR Tablets in Healthy Volunteers

The study is designed to evaluate the bioequivalency between the test formulations 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.

Inclusion Criteria:

• Having a body mass index (BMI) within normal standard limits (18.5~24.9, inclusive).
• Willing and able to give informed consent to participate in the clinical study and comply with all study procedures, restrictions and attend all visits.

Exclusion Criteria:

• History of bleeding tendency.

• Use of anticoagulant agent(s) within 1 month prior to screening.

• Use of tobacco or nicotine products within 6 months of screening.

• Intake of over the counter or prescription drugs (other than hormonal contraceptives) within 2 weeks prior to randomization.

• History of substance abuse, such as alcohol, IV drugs, and inhaled drugs, within 1 year prior to screening.

• Known history of having Acquired Immunodeficiency Syndrome (AIDS) or positive pre-study result of infection with Human Immunodeficiency Virus (HIV); history or positive pre-study Hepatitis B surface antigen or positive Hepatitis C antibody result within 3 months of screening.

• Pregnant or breast feeding.

  1. Post-menopausal: 12 months of natural (spontaneous) amenorrhea or less than 12 months of spontaneous amenorrhea with serum Follicle Stimulating Hormone (FSH) levels > 40IU/L, OR;
  2. 6 weeks post-surgical bilateral oophorectomy with or without hysterectomy, OR;
  3. Using one or more of the following acceptable methods of contraception: surgical sterilization (e.g. bilateral tubal ligation), hormonal contraception (e.g. implantable, injectable, vaginal patch, and oral), and double-barrier methods. Reliable contraception should be maintained throughout the study and for 7 days after study discontinuation.

• Known or suspected hypersensitivity to any ingredient of study drug(s).

• Donated blood or lost more than 150 mL of blood within 3 months prior to randomization or plans to donate blood or plasma within 4 weeks after completion of the study.
