What is difference between alpha blocker and beta blocker?

Beta blockers may be cardioprotective but in contrast to alpha-1 antagonists tend to have adverse effects on plasma lipids. Drugs with combined beta and alpha-1 blocking activity such as labetalol have favorable metabolic effects but postural hypotension remains a problem.

What is combined alpha and beta blocker?

Combined alpha and beta-blockers are used as an IV drip for those patients experiencing a hypertensive crisis. They may be prescribed for outpatient high blood pressure use if the patient is at risk for heart failure.

What are alpha blockers examples?

Alpha blockers are a class of adrenergic blockers that work by antagonizing alpha adrenoceptors in the body. Examples include Cardura, Cardura XL (doxazosin), Minipress (prazosin), terazosin, Flomax (tamsulosin), Uroxatral (alfuzosin ER) , Rapaflo (silodosin), and Dibenzyline (phenoxybenzamine).

Which drugs are alpha blockers?

Are beta blockers vasodilators or vasoconstrictors?

beta 1-blockers with beta 2 agonist activity are vasodilatory because they activate postsynaptic beta 2 receptors on vascular smooth muscle cell membranes, via the formation of cyclic AMP.

Where are alpha and beta receptors?

Alpha receptors and beta receptors are both located postsynaptically at the sympathetic junctions of several organs. You can find these receptors in the heart, blood vessels, airways, uterus, fatty tissues, and many other areas. There are two main types of alpha receptors: alpha 1 and alpha 2.

Why should alpha blockers be given before beta blockers?

Beta blockers are used if significant tachycardia occurs after alpha blockade. Beta blockers are not administered until adequate alpha blockade has been established, however, because unopposed alpha-adrenergic receptor stimulation can precipitate a hypertensive crisis.

Can alpha blocker and beta-blocker be used together?

Sometimes, a beta-blocker is combined with an alpha-blocker. This may be useful for men who have hypertension and an enlarged prostate. The alpha-blocker may help both problems at the same time. Other combinations may include an ACE inhibitor with a thiazide diuretic.
