Pharmacodynamic <99% BEST>

Central to pharmacodynamics is the , which quantifies how the intensity of an effect changes with varying drug concentrations. This is typically visualized using a concentration-response curve. Key metrics include: Emaxcap E sub m a x end-sub : The maximal effect a drug can produce regardless of dose. EC50cap E cap C sub 50

: Trigger intracellular signal cascades. pharmacodynamic

Beyond receptors, drugs may also target enzymes (such as NSAIDs inhibiting cyclooxygenase), transporters, or ion channels directly. Agonists, Antagonists, and Affinity Central to pharmacodynamics is the , which quantifies
