Durkat 2014 Exam 2 pg 1 #. Serotonin 5-HT2 receptors are metabotropic receptor believed to be involved in the action of hallucinogens; they might also play a role in depression and psychosis. The dose-response curves below represent drugs A, B, and C that possess affinity for 5-HT2 receptors, but differ in their intrinsic activity. Effect vs. Log D Conc graph Drug C (100% Effect with higher curve) Drug A ( Lower curve) Drug B (Flat line) Drug A possesses an intrinsic activity α of _...

dose-response curve correct answers • when the relationship between the dose and the response is plotted as a graph • as the dose increases so does the magnitude of the response • eventually a maximal response is obtained, further increases in the dose do not produce an greater effect= ceiling effect point on graph • Doses above the ceiling effect cause the toxic or other undesired effects • Not all drugs have a ceiling effect • Used to evaluate drug response among different dr...
