Drug design involves inventing new pharmaceutical drugs based on knowledge of biological targets, with classes of medications defined by their chemical properties, routes of administration, effects on biological systems, and therapeutic effects. The Anatomical Therapeutic Chemical classification system categorizes drugs into groups such as antipyretics, analgesics, antimalarial drugs, antibiotics, and antiseptics based on their medical use. Strategies for drug design include ligand-based and structure-based approaches.
