Concept Introduction:

Drugs: Drugs are molecules which are taken from an external source to change the normal functioning of the body. The action of drug is in molecular level and the design of many drugs are in such a way that it mimics a particular neurotransmitter or hormone. Drugs bind with receptors showing an increased or decreased effect.

There are two types of drugs and they are agonist and antagonist.

Agonists are chemical substance that binds with a receptor so that it activates the receptor for producing or prolonging its normal biochemical response.

Antagonists are chemical substance that binds with a receptor so that it blocks or inhibits the normal biochemical response of a particular receptor.

Curare is a chemical substance which acts as an antagonist for the neurotransmitter acetylcholine by binding with its receptor.
