Reserpine can lower blood pressure and slow heart rate, the role of slow, gentle and long-lasting, lasting on the stability of the central nervous system function, is a good sedative. Function as follows:
1. Reserpine was blocked by adrenergic neurons of antihypertensive drugs.
2. This product is the depletion of peripheral sympathetic nerve endings of adrenaline, heart, brain and other tissues of catecholamines and 5 - HT to anti-high blood pressure, slow heart rate and inhibition of the central nervous system. Antihypertensive effect primarily by reducing cardiac output and reduced peripheral resistance, part of the cardiovascular reflex inhibition to achieve.
3. Reserpine acts on hypothalamic area produce sedation, but no cause drowsiness and anesthetic effects, does not change the sleep EEG, can ease the anxiety of patients with hypertension, tension and headaches.
4. Experimental animal for less than the clinical dose of reserpine, which appears miosis, eyelid wrinkles and sagging, hypothermia, gastrointestinal symptoms such as the acceleration of activity.
