“The effects of OT were also blocked by hexamethonium , a ganglionic blocking agent, by atropine, a muscarinic receptor antagonist, and by N(omega)-nitro-L-arginine methyl ester, an inhibitor of nitric oxide synthesis.”

“Cardiac responses were induced when oxytocin was reinjected into active intrathoracic ganglionic sites after whole body administration of hexamethonium (10 mg/kg IV), but not after local administration of timolol into the ganglia.”
“Administration of hexamethonium systematically, to block nicotinic transmission in autonomic ganglia, prevented the cardioacceleration in response to intrathecal administration of oxytocin.”
