Pharmacokinetic and Drug Interaction Study of Red Yeast Rice Capsules

Study Overview
=================
Brief Summary
-----------------
Red yeast rice capsule (LipoCol Forte)is a nature product that has been demonstrated a significant cholesterol lowering effect which might be caused by addictive and/or synergistic effects of lovastatin (monacolin K) with other monacolins and substances in capsules. The usual dose of red yeast rice capsule(LipoCol Forte)for hypercholesterolemia is one capsule twice/day. However, the pharmacokinetic profile of red yeast rice capsule (LipoCol Forte)is still unknown. The objective of the study is to evaluate the pharmacokinetic profile of red yeast rice capsule (LipoCol Forte) after administering single and multiple dose to healthy subjects.

Detailed Description
-----------------
This study will divide into two groups, single and multiple doses groups. In single dose group, the subjects will receive one, two and four red yeast rice capsules under fed state in period one to three, respectively. In multiple doses group, the subjects will receive red yeast rice capsules under fed state twice daily for 4.5 days. There is a minimum of a 5-days washout period before crossover of treatments. In single dose treatment, the blood samples will be drawn prior to the dosing, and 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8 and 12 hours after the dosing. In multiple doses treatment, the blood samples will be drawn prior to the 1st dosing, prior to the 7th dosing, prior to the 8th dosing, prior to the 9th dosing, and 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8 and 12 hours after the 9th dosing.
