Pharmacodynamics: Pharmacy Exam! Quiz

Pharmacodynamics is the study of how drugs affect the body on a chemical and psychological level. A pharmacist needs to know how different drugs react to a patient, to prescribe the right one. In this quiz, you will get to test out all the basics of this study. Check it out and see how well you will do!
