In pharmacology, the potency of a drug refers to the amount needed to achieve a specific effect. A drug with higher potency will require a lower dose to produce that effect compared to a drug with lower potency.
Given a graph that compares the potency of drugs A, B, and C, the key to determining the highest potency lies in evaluating which drug achieves the desired effect at the lowest dose. Typically, on such graphs, the x-axis represents the dose, and the y-axis represents the effect. A drug curve closer to the y-axis (achieving the effect at a lower dose) indicates higher potency.
Based on this understanding, we analyze the position of the curves representing Drugs A, B, and C. The drug with the curve closest to the y-axis will have the highest potency.
In the given graph, Drug A shows the desired effect at the lowest dose on the x-axis, indicating that it is the most potent among the three drugs.
