Organic Functional Groups for Naming of Drugs

Organic Functional Groups 

Nomenclature of Drugs:

Most of the drugs in current usage are organic in nature, so we must have knowledge on Organic compounds. most of the drugs contain one or other functional groups.

I listed some different functional groups and heterocyclic systems.

This list of some organic groups usually coming across in the naming of the drugs.
