How do medical drugs work?

 Q:   Ask a Question about How do medical drugs work?       
How do medical drugs work? Many medical drugs work by correcting the chemical reactions within the body that are responsible for disease. For example, insulin injections replace insulin that is not being produced by the pancreas, so sugar can be used properly by the body. In depression and mental illness, drugs can restore the balance of chemicals in the brain.

Aspirin is often given to cure a headache, but it can also neutralize the inflammation that causes pain in the joints of people suffering from arthritis.

Modern drug research studies the cause of diseases, then designs molecules that interrupt or reverse the disease process. All drugs cause some unwanted effects, and scientists try to find new drugs that relieve disease without causing further problems.

Modern drugs have been developed to cure or control many illnesses, and now new drug molecules can be designed to have particular properties.
