About

The purpose of this study is to evaluate and compare the relative bioavailability and therefore the bioequivalence of a test formulation of lovastatin tablets to an equivalent dose of Mevacor® tablets after a single oral dose administered under fasting conditions.

Full description

Fifty-four healthy, light/non/or ex-smoking, non-obese, male volunteers at least 18 years of age will be randomly assigned in a crossover fashion to receive each of two lovastatin dosing regimens in sequence with a 7 day washout period between dosing periods. On the morning of Day 1, after an overnight fast of at least 10 hours, subjects will receive either a single oral dose of the test formulation, lovastatin (1 x 40 mg tablet), or a single oral dose of the reference formulation, Mevacor® (1 x 40 mg tablet). After a 7 day washout period on the morning of Day 8, following an overnight fast of at least 10 hours, subjects will receive the alternate regimen. Blood samples will be drawn from all participants before dosing and for 24 hours post-dose on a confined basis at times sufficient to adequately define the pharmacokinetics of lovastatin. Blood sampling will then continue on a non-confined basis at 36 and 48 hours post-dose. A further goal of this study is to evaluate the safety and tolerability of this regimen in healthy volunteers. Subjects will be monitored throughout the confinement portion of the study for adverse reactions to the study drug and/or procedures. Vital signs will be monitored if judged necessary by the physician in charge. All adverse events whether elicited by query, spontaneously reported, or observed by clinic staff will be evaluated by the Investigator and reported in the subject's case report form.

Presence of significant gastrointestinal, liver or kidney disease, or any other conditions known to interfere with the absorption, distribution, metabolism or excretion of drugs or known to potentiate or predispose to undesired effects
History of significant gastrointestinal, liver or kidney disease, or surgery that may affect drug bioavailability, including but not limited to cholecystectomy
Presence of significant cardiovascular, pulmonary, hematologic, neurologic, psychiatric, endocrine, immunologic or dermatologic disease
