1. An effective drug would have:

A. low affinity

B. high affinity

C. high affinity and acts at sites of action that produce therapeutic effects

D. low affinity and acts at sites of action that produce therapeutic effects

Solution

In order for a drug to have an effect, it needs to bind to its target and affect the function of the target. Nature with which the drug binds to its target is termed as its affinity and efficacy would be a measure of the action of a drug once the binding has occurred. The combined influence of both affinity and efficacy will determine how effective that drug is.

An effective drug would have high affinity and acts at sites of action that produce therapeutic effects.
