Several key parameters are commonly studied in pharmacodynamics to understand drug action:
1. EC50 (Effective Concentration 50%): The concentration of a drug that produces 50% of its maximum effect. 2. Emax (Maximum Effect): The maximum effect that can be achieved with a drug. 3. Therapeutic Window: The range of drug doses that produces therapeutic effects without causing significant adverse effects. 4. Receptor Binding: The interaction of a drug with its target receptors, which can influence its efficacy and potency.
