On a dose-response (curve) graph, which is the more potent drug?
Show answer and explanation
Correct answer: A. Drug A
- A. CORRECT. Potency relates to the position on the dose axis. The curve shifted to the left (Drug A) reaches its effect at a lower dose, so it is more potent.
- B. INCORRECT. Drug B's curve is shifted right, requiring a higher dose for the same effect, so it is less potent.
