Peptide Efficacy

Meaning

Peptide Efficacy is the clinical and pharmacological measure of the maximal functional response or therapeutic effect that a specific peptide drug can produce upon binding to its designated receptor target, reflecting its intrinsic activity. This metric is a crucial determinant of a peptide’s true clinical value, quantifying the magnitude of the desired physiological outcome achievable at saturating concentrations. Efficacy is distinct from potency, which merely describes the concentration required to elicit a response, focusing instead on the ceiling of the biological effect.
