Question

why do we need to classify drugs in different ways??​

Answer 1

Explanation:

We need to classify drugs in different ways because different drugs are effective against the particular micro-organism responsible for the disease. Drugs can be classified in the following ways:

(i) on the basis of pharmacological effect.

(ii) On the basis of action on a particular biochemical process.

Answer 2

Answer:

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

(i) 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.  

(ii) 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.  

(iii) On the basis of chemical structure:  

• This classification provides the range of drugs sharing common structural features and often having similar pharmacological activity.  

(iv) 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.
