Drugs in this class inhibit α-adrenoceptors, thereby reducing the α-effects of endogenously released NE. B. NONSELECTIVE antagonists block both α1- and α2-adrenoceptors. 1. The properties of the various α-antagonists are quite different. a. Phenoxybenzamine (Dibenzyline) is an alkylating agent that forms a reactive intermediate.
