Time Stamps: 00:00 Resting State of the Receptor and Receptor Activation 01:21 Intrinsic Activity/ Intrinsic Efficacy 03:20 Intrinsic Activity of Full, Partial and Inverse Agonists 09:15 Full, Partial and Inverse Agonists on a bar graph 12:48 Concentration-Response Curve (CRC) or Dose-response Curve (DRC) 14:54 Efficacy and Potency 26:39 Spare Receptors/ Reserve Receptors The efficacy of a drug is the maximum response achievable from a drug regardless of the drug potency. Note that a drug may have a high efficacy but not be potent, i.e. the drug may have a high maximal response (Emax) but require a lot of the drug to do so. If an analgesic can relieve hundred percent of a patient's pain but requires 2000 mg to do so, this drug has a high efficacy but a low potency. Conversely, a drug can have a high potency (small amount of drug required to get 50% of the maximal response) but have a low efficacy (partial agonist). A drug can be less potent but still highly efficacious (Emax = 100%). Do not get confused by this concept. Remember potency and efficacy are independent of each other. Refer to the graphs in this video to illustrate this concept.
