Diagnose and prevent – Drugs are also used to diagnose and prevent illness. There are drugs which are used in laboratory set up in order to diagnose an illness. In medical set up, drugs are also used to prevent the occurrence of a disease condition.

Healing –The most important medical use of drugs in any medical set up is to heal the disease condition. Healing process occur when the disease causing organisms are destroyed and the damages they had been caused to body cells recovered.
