Maximum drug and metabolite concentration, Time to reach maximum concentration, Half-life of drug and metabolite

People in the mentioned age group are invited to participate through the advertisement. People are then checked for health and healthy volunteers are identified. Each candidate is assigned a number from 1 to 24. The numbers are written on a plastic ball, poured into a container, and mixed. The balls are then removed randomly from the container. The first 12 no.s are considered as (first sequence: Zistdaru Danesh's medicine ) and the second 12 no.s are considered as (second sequence: originator brand recipient).
