Clinical Bioequivalence Study on Two Paracetamol Tablet Formulations

Clinical Bioequivalence Study on Two Paracetamol Tablet Formulations

The objective of the study is to compare the bioavailability of a generic product of paracetamol (immediate-release) with that of a reference product when administered to healthy volunteers under fasting condition. The test product is Fortolin Tab 500mg manufactured by Fortune Pharmacal Co. Ltd., and the reference product is Panadol Caplet 500mg manufactured by GlaxoSmithKline (Dungarvan) Ltd. The plasma pharmacokinetic data of paracetamol obtained from two formulations will be used to evaluate the interchangeability of the products.
