Question

Quizplus · Accepted Answer

A dose-effect curve shows the relationship between different doses of a drug and the corresponding magnitude of the drug effect. It helps determine the optimal dose of a drug for achieving the desired therapeutic effect while avoiding any adverse effects. The curve typically shows a graded response, with increasing doses leading to an increasing effect until a maximum effect is reached, after which further increases in dose do not produce any additional benefit and can result in toxicity. Therefore, the dose is the key factor depicted on the curve.
