A partial agonist has:
AHigh affinity with low intrinsic activity
BHigh affinity with no intrinsic activity
CLow affinity with high intrinsic activity
DLow affinity with low intrinsic activity
In isolated intestinal smooth muscle preparations, drug X binds to cholinergic receptors and causes relaxation. In the absence of drug X, acetylcholine binds to the same receptors and causes contraction. At low concentrations of drug X, the efficacy (Emax) of acetylcholine is decreased, but its potency (EC50) remains unchanged. At high concentrations of drug X, acetylcholine has no effect. Which of the following statements about drug X is true?
AA chemical antagonist
BA physiologic antagonist
CNon-competitive antagonist
DCompetitive antagonist
Which of the following statements is correct regarding the given graph?
ADrug 1 represents agonist and drug 2 represents inverse agonist
BDrug 3 represents agonist and drug 4 represents inverse agonist
CDrug 2 represents partial agonist and drug 3 represents inverse agonist
DDrug 1 represents agonist and drug 4 represents inverse agonist
