Affinity

Synonyms or meaning of Affinity

“Affinity” in the context of pharmacology refers to the degree of physical-chemical attraction between a drug and its receptor site. It essentially measures the strength of the bond between a drug or an endogenous substance (a substance originating from within an organism, tissue, or cell) and a receptor. A higher affinity indicates that the drug binds more readily to the receptor, which can influence the drug’s efficacy. This concept is crucial in drug design and pharmacodynamics.
