Question

why the drug should be specific in action​

Answer 1

Explanation:

The action of drugs on the human body is called pharmacodynamics, and what the body does with the drug is called pharmacokinetics. The drugs that enter the human tend to stimulate certain receptors, ion channels, act on enzymes or transporter proteins. As a result, they cause the human body to react in a specific way.

There are 2 different types of drugs:

Agonists - they stimulate and activate the receptors

Antagonists - they stop the agonists from stimulating the receptors

Once the receptors are activated, they either trigger a particular response directly on the body, or they trigger the release of hormones and/or other endogenous drugs in the body to stimulate a particular response.
