Brief Summary

Prospective, Randomized, Crossover, Bioequivalence study

Detailed Description

Active-control crossover study randomizing 32 healthy volunteers to receive one of two dose levels, 325 mg or 650 mg, of either PL-ASA or immediate release aspirin within a two week washout period between treatments. The primary objectives are to assess PK and PD bioequivalence and safety over a twenty four hour period for PL-ASA and immediate release aspirin at 325 mg and 650 mg dose strengths.
