Chemical kinetics as the title suggests holds most significance in determining the efficacy of various biologically important components especially the interactions and the release of the drugs. The study holds its prominence in various fields most importantly being the formulations of new drugs. In this mini review we focus on the comparative study on drugs functioning with their kinetics known and hence to relate its significance with its reaction rates. The review is an effort to understand the reaction rates of various drugs and how this influences its release into the body.
