The classification of drugs and the reasons for classification are as follows:

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. Hence, it is the most useful to medicinal chemists.
