Affinity refers to the strength with which a drug binds to its receptor, while potency describes the amount of drug required to produce a specific biological effect.

Potency is influenced by multiple factors, including affinity, efficacy, receptor density, and signal amplification. Therefore, while affinity contributes to potency, it is only one of several components.

Ultimately, potency reflects the overall effectiveness of a drug within a biological system—not just how well it binds to its target.

Affinity is an intrinsic property that describes how tightly a drug binds to its receptor. Efficacy refers to the maximum effect a drug can produce once it’s bound to the receptor. Both affinity and efficacy are independent of drug concentration.

Because it has an α value of 1. A drug with an α value of 1 is considered a full agonist, meaning it can produce the maximum possible response in a system.
