Alpha blockers, also known as α-blockers or α-adrenoreceptor antagonists, are a class of pharmacological agents that act as antagonists on α-adrenergic receptors (α-adrenoceptors). [2] Historically, alpha-blockers were used as a tool for pharmacologic research to develop a greater understanding of the autonomic nervous system.
Alpha 1 blockers cause vasodilation by relaxing smooth muscles that control blood vessel diameter, leading to lower blood pressure. [1] FDA-approved uses of these drugs include treating conditions like benign prostatic hyperplasia, hypertension, pheochromocytoma, extravasation management, and reversal of local anesthesia.
Alpha 1 blocker exerts its action on alpha-1 receptor, dilating the smooth muscles. [3] Alpha-1 receptor is a Gq type G-protein coupled receptor . [ 3 ] When it is activated, it will lead to activation of phospholipase C , raising the intracellular level of IP3 and DAG . [ 3 ]
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]
The tetracyclic antidepressants mianserin and mirtazapine are α 2 blockers, although their efficacy as antidepressants may come from their activity at other receptor sites. [citation needed] Mechanistically, α 2 blockers increase adrenergic, dopaminergic and serotonergic neurotransmitters and induce insulin secretion, decreasing blood sugar ...

Tamsulosin is an alpha blocker and works by relaxing muscles in the prostate. [10] Specifically it is an α 1-adrenergic receptor blocker. [6] Tamsulosin was approved for medical use in the United States in 1997. [6] It is available as a generic medication. [9]
Labetalol is a beta blocker, or an antagonist of the β-adrenergic receptors. It is specifically a non-selective antagonist of the β 1-and β 2-adrenergic receptors. [17] Labetalol has intrinsic sympathomimetic activity. [17] It is also an antagonist of the α 1-adrenergic receptor, and hence is additionally an alpha blocker.
