  "term": "Potency",
  "field": "Chemistry",
  "definition": "A measure of drug activity expressed in terms of the amount required to produce an effect of given intensity. A highly potent drug evokes a larger response at lower concentrations compared to a less potent one. This characteristic is often quantified by the EC50 or IC50 value, representing the concentration needed for 50% of the maximal effect or inhibition, respectively.",
