Why do drugs designed to cure some ailments in one organ in the body not affecting the other parts ?!.. Explain with an example.

Dear student
Please find below the solution to the asked query:

The diseases are organ specific in nature.
For example, each microorganism which enters our body effects a particular type of tissue/organ and damages that organ.
Thus the drugs designed today are also disease specific. 
These drugs/medicines are so designed that they form a complex with the disease present in a specific organ and cure the disease by break down. It does not harm other parts of the body, but often some side effects are seen.
If a microbe enters our body through the nose, then it is most likely to reach the lungs. The bacterium that causes tuberculosis enters via the nose and affects the lungs. This is thus cured by specific drugs like 
  • Isoniazid. and Rifampin . These drugs do not affect other organs of the body and cure the lungs only.
