Drug classifications organize the many medications used in health care and help nurses anticipate why a medication is prescribed, how it works, and what effects or risks may occur. This lesson explains therapeutic and pharmacologic classifications and shows how prototype drugs make learning and clinical reasoning more manageable.
Most drugs can be described using both a therapeutic classification and a pharmacologic classification. These classifications answer different questions: what clinical purpose does the drug serve, and how does it work?
