Abstract: | H80/62, recently introduced as a beta 1-selective adrenoceptor agonist, caused a long-lasting flow of saliva from parotid and submaxillary glands of the rat. The effect of H80/62 was prevented by propranolol or a beta 1-selective blocker. The drug did not exert its effect via the sympathetic postganglionic nerves; and it was not taken up by the neuronal amine pump. Sympathetically decentralized or denervated glands acquired a supersensitivity of the postjunctional type to H80/62. |
