Executive Summary
RATE OF EXPOSURE MEASUREMENTS COULD REPLACE Cmax BIOEQUIVALENCE studies, FDA Division of Pharmaceutical Evaluation II Director Mei-Ling Chen, PhD, told FDA's Advisory Committee for Pharmaceutical Science June 23. "Instead of rate and extent of absorption" for determining bioequivalence, "you may characterize the drug's profile in terms of rate of exposure, which may be composed of three measures: total exposure, peak exposure and early exposure," Chen said.
