1. Antagonistic properties of OPC-28326 ([4-(N-methyl-2-phenylethylamino)-1-(3,5-dimethyl-4-propionyl-aminobenzoyl)] piperidine hydrochloride monohydrate), a selective peripheral vasodilator, were investigated by analysing the data from functional studies in various tissues from the rat and binding studies of the drug to alpha(2)-adrenoceptor subtypes. 2. Using a...
