Good Clinical Practice

Abstract

Trials evaluate the safety of a Drug. This first phase of testing, which can take many months to complete, usually includes a good number of healthy volunteers (25 to 100), who are generally paid for participating in the trials. The trial is designed to determine the effect of the Drug on healthy humans including how it is behaves or act (absorbed, distributed, bio transformed and eliminated). This phase also examine the adverse effects that occur at different dosage are increased or decreased. About seventy percent of experimental drugs pass this phase of testing.
