Quizplus · Accepted Answer

The location of the dose-response curve along the horizontal axis reflects the potency of a drug, which is the amount of drug needed to produce a particular effect. This is because the horizontal axis represents the dosage or concentration of the drug, and potency is defined as the minimum effective dose or concentration of a drug. The curve itself reflects the relationship between dose (or concentration) and effect, but its position along the horizontal axis is determined by the drug's potency. The therapeutic index, efficacy, and individual differences in drug response may all affect the shape of the curve, but they do not determine its position along the horizontal axis.
