The Most Successful Medications For High Blood Pressure
Alpha-Blockers

Similar to beta-blockers, alpha-blockers help the blood vessels dilate, or open up, as well as block the hormone adrenaline, which naturally narrows the blood vessels. Specifically, alpha-blockers reduce nerve impulses to the blood vessels, reducing the effects of adrenaline and other bodily chemicals that cause the narrowing of blood vessels, as well as slowing down a patient’s heartbeat. As the blood vessels begin to relax due to alpha-blockers, blood flow increases and blood pressure decreases. The most commonly available alpha-blockers include doxazosin, carvedilol, labetalol, prazosin, indoramin, and terazosin.
