Pharmacological Action

Infusion of puerarin into the coronary artery of an anesthetized dog shows an increase in cerebral blood flow and a decrease in vascular resistance, so that it can prevent myocardial ischemia caused by neurohypophysin. Both in vivo and in vitro experiments have demonstrated that puerarin can exert competitive β-receptor antagonism on rabbit arterial smooth muscle and airway smooth muscle, and can reduce blood pressure and heart rate in spontaneously hypertensive rats, but has little effect on normal Wistar rats. Puerarin inhibits the Na current against tematokia in the central spinal nerve root of rats (the puffer virus is a sodium channel-specific blocker that blocks the inward Na current) and has neuroprotective effects on cerebral ischemia. And by expanding the intracranial arteries, the cerebral blood flow is improved, and the effect is dose dependent. Puerarin also has a blood pressure lowering effect, especially renal hypertension.
