Question

Quizplus · Accepted Answer

A high receptor affinity means that the drug has a strong attraction to the receptor and is more likely to bind to it. This suggests that the drug will outcompete drugs with lower affinities, meaning it will bind to the receptor more often or for longer periods of time than other drugs. It does not necessarily indicate whether the drug will activate or block the receptor, or have a large value for a dissociation constant.
