Abstract
Interaction of arterial 5-HT2 receptors with their ligands are variable and complex. Some produce a surmountable, apparently competitive inhibition of the effects of 5-hydroxytryptamine (5-HT), causing a simple rightward shift of the concentration-effect curve for 5-HT. Other antagonists cause a rightward shift of the concentration-effect curve and a depression of maximum responses to 5-HT which cannot be surmounted by increased concentrations of 5-HT. However, in some cases, the unsurmountable action of one antagonist can be prevented or reversed by exposure to another, surmountable antagonist.
