What is the basis of most useful classification of medications in medical chemistry?

Correct answer: (b) Molecular targets

Explanation

For medicinal chemists, the most useful drug classification is based on molecular targets, the biomolecules a drug acts upon.

These targets are mainly proteins, carbohydrates, lipids and nucleic acids such as receptors and enzymes.

Drugs sharing a target often have a common mechanism of action, which is more useful than grouping by chemical structure.
