Studies of certain autonomic responses of reserpine and tetrabenazine show that miosis, salivation and lacrimation are caused by stimulation of the parasympathetic component of the central autonomic nervous system. These compounds also induce an enhanced light reflex which is responsible for the active closure of eyelids and for the sustained miosis in the light. In contrast chlorpromazine does not increase parasympathetic tone nor does it enhance the light reflex.
