This program typically takes four years to complete after obtaining a bachelor's degree, focusing on subjects like pharmacology, medicinal chemistry, and patient care. Pharm.D. graduates are trained to understand medications, their effects, and how to manage patient therapy. They play a crucial role in healthcare teams, ensuring safe and effective medication use.
