Adrenoceptors were classified as α- and β-receptors by Ahlquist (1). The α-receptor is generally associated with the excitatory functions and α the β-receptor with the inhibitory functions in various smooth muscles. Stimulation of the α- and β-receptors in intestinal smooth muscles produces a relaxation (2). Our knowledge of the receptor reserve of α-receptor for the α-adrenoceptor stimulants has been, however, obtained from data in the excitatory responses (3, 4). Little is known of the receptor reserve for the α-agonists in inhibitory mechanisms.
