Drug-Target Interaction — Prelims Strategy

Prelims Strategy

To effectively tackle NEET questions on Drug-Target Interaction, a multi-pronged strategy is essential. Firstly, master the core definitions: clearly distinguish between terms like agonist, antagonist, enzyme inhibitor (competitive vs.

non-competitive), and understand what constitutes a 'drug target'. Use flashcards for these definitions. Secondly, memorize key examples: NCERT provides specific examples of drugs and their mechanisms (e.

g., aspirin inhibits COX enzymes, antihistamines block histamine receptors, tranquilizers enhance GABA action). Create a table linking drug class, specific drug examples, their target, and their mechanism (agonist/antagonist/inhibitor).

Thirdly, understand the underlying chemistry: be familiar with the types of intermolecular forces (hydrogen bonds, ionic, van der Waals, hydrophobic) that govern drug binding. Conceptual questions often revolve around these forces and the concept of specificity.

For numerical problems (though rare in this specific subtopic, more common in kinetics), ensure you can apply relevant formulas. Finally, practice MCQs diligently: pay close attention to trap options, which often involve confusing similar-sounding terms or misattributing mechanisms to the wrong drug class.

Always read the question carefully to identify what is being asked (e.g., 'correct' vs. 'incorrect' statement).
