Medication Potency

Meaning

Medication potency is a pharmacological measure that quantifies the amount of drug required to produce a specific effect of a given intensity. Specifically, it is often represented by the EC50 (half-maximal effective concentration) or ED50 (half-maximal effective dose) value, indicating the drug concentration or dose needed to achieve 50% of the maximum possible response. Potency is a key factor in determining the appropriate therapeutic dosage and is distinct from drug efficacy, which refers to the maximum effect achievable.
