What is Affinity?

Affinity refers to the strength of binding between a drug molecule and its target site, such as a receptor. It measures the interaction between the drug and the target site and determines the ability of the drug to bind and activate the receptor.

High affinity drugs bind tightly and specifically to the target site, while low affinity drugs have weak binding and may bind to other sites. The affinity of a drug is an important factor in determining its potency and efficacy.
