Alpha-1 blocker, blocks alpha receptors and it relaxes the smooth muscles in the bladder. It helps the urine to flow smoothly and it can lessen the pain caused by the bladder pressing on the prostate. [44] [45] Selective alpha-1 blockers are better tolerated than non-selective alpha blockers in the body and therefore works better on BPH. [2]
Non-selective alpha blocker: Paroxysmal hypertension, pheochromocytoma-induced sweating [24] Dibenzyline [25] Phentolamine: Non-selective alpha blocker: Reversal agent for unnecessary prolonged local analgesia [26] Regitine [27] Prazosin: Selective alpha-1 blocker: Hypertension, benign prostatic hyperplasia, PTSD associated nightmares and ...
When the term "alpha blocker" is used without further qualification, it can refer to an α 1 blocker, an α 2 blocker, a nonselective blocker (both α 1 and α 2 activity), or an α blocker with some β activity. [2] However, the most common type of alpha blocker is usually an α 1 blocker. Non-selective α-adrenergic receptor antagonists include:
Clinically, non-selective alpha antagonists block alpha receptors (but do not differentiate between alpha-1 and alpha-2). They are used as antihypertensives because they block alpha-receptor-mediated vasoconstriction. The block on alpha-2 receptors further potentiates beta-effects, increasing cardiac output.
The older, less selective α1-adrenergic blocker prazosin is not a first-line choice for either high blood pressure or prostatic hyperplasia; it is a choice for patients who present with both problems at the same time. The older, broadly non-selective alpha-blocker medications such as phenoxybenzamine are not recommended for control of BPH. [74]
Prazosin is an α 1-blocker that acts as a non-selective inverse agonist at α 1-adrenergic receptors, including of the α 1A-, α 1B-, and α 1D-adrenergic receptor subtypes. [24] It binds to these receptors with affinity (K i ) values of 0.13 to 1.0 nM for the α 1Α -adrenergic receptor, 0.06 to 0.62 nM for the α 1B -adrenergic receptor ...
