Pharmacology Made Simple: Foundations — How Drugs Work in the Body

This is Book 1 of the Pharmacology Made Simple series. Master these fundamentals — what the body does to a drug, and what the drug does to the body — and every drug class you study afterward becomes far easier to understand and remember.
