Description
  • The graph is a log dose-response curve with log drug dose on the x-axis and % of maximal effect on the y-axis
  • The curve sigmoid in shape
  • The height of the curve is the maximal effect which for a full agonist is 100%
  • The curve always passes through the ED50
  • For a full agonist (A) this is always at 50% of maximal effect
  • A full agonist of lower potency has a higher ED50, thus shifting the curve to the right
