Pharmacology Hardest MCQ Exam: Quiz

Welcome to this challenging pharmacology exam practice test. Pharmacology is the study of how drugs react when they are introduced to the body and their general effect. Did you know that Orlistat is a drug used to treat obesity because it prevents fats from being absorbed? Do take this challenging quiz and get to see how much you know about drugs, their side effects, etc.
