# Lists of drugs

There are many hundreds of thousands of possible drugs. Any chemical substance with biological activity may be considered a drug. This list categorises drugs alphabetically and also by other categorisations.
This multi-page article lists pharmaceutical drugs alphabetically by name. Many drugs have more than one name and, therefore, the same drug may be listed more than once. Brand names and generic names are differentiated by capitalizing brand names.

Abbreviations are used in the list as follows:
* INN = International Nonproprietary Name
