Question

Why do we need to classify drugs in different ways?

Answer 1

There are a vast no. of drugs and we cant keep them in a single category since they are different in structure and they show different action. even when they enter the body the affect on different target. There fore there is a need to categorise these drugs on various basis as--


1 On the basis of pharmacological effect:
This classification provides doctors the whole range of drugs available for the treatment of a particular type of problem. Hence, such a classification is very useful to doctors.

2 On the basis of drug action:
This classification is based on the action of a drug on a particular biochemical process. Thus, this classification is important.

3) On the basis of chemical structure:
This classification provides the range of drugs sharing common structural features and often having similar pharmacological activity.

4. On the basis of molecular targets:
This classification provides medicinal chemists the drugs having the same mechanism of action on targets.

Answer 2

$\huge\underline{\bold{Answer :-}}$

___________________________________________

There are a large variety of drugs for different purposes of diagnosis, prevention, relief or cure of different diseases. These have been classified according to various criteria depending upon their :-

$\bigstar\underline{\pink{\bold{Pharmacological\:effect.}}}$

$\bigstar\underline{\green{\bold{Their \:action\: on\: a \:particular \:biochemical\:process.}}}$

$\bigstar\underline{\orange{\bold{On\:the\:basis\:of\:their\:chemical\:structure.}}}$

$\bigstar\underline{\red{\bold{On\:the\:basis\:of\:molecular\:targets.}}}$

These classifications have their own usefulness. For example,

● Classification on the basis of pharmacological effect of the drugs :

This classification is useful to doctors because it provides them the whole range of drugs available for the treatment of a particular type of disease.

● Classification on the basis of action on a particular biochemical process :

This classification is useful for selecting the correct lead compound for designing the synthesis of a desired drug.

● Classification on the basis of chemical structure:) :

This classification helps to design the drugs having similar pharmacological activity and then selecting the drug with least toxicity.

● Classification on the basis of molecular targets :

This is useful for medicinal chemists so that they can design a drug which is most effective for a particular acceptor site.

Altogether, we can say that such classification of drugs in different ways helps to use and study these drugs more easily and distinctively. Hence, the need for such a classification becomes necessary.
