Pharmacology Pharmacokinetics Introduction

Different drugs have different ways in which they enter the body and attack the base for an illness or diseases. The pharmacokinetic process is concerned with the absorption, distribution and elimination of drugs. In the Pharmacology class we got to learn more on pharmacokinetics and the test below is designed to see how much you understood. Give it a try!
