Alpha-blockers are drugs that slow down or block certain types of cell activity. They’re used for high blood pressure, prostate problems and certain types of tumors.
22 Ogo 2023 · Alpha blockers lower blood pressure by keeping a hormone called norepinephrine from tightening the muscles in the walls of smaller arteries and veins. As a result, the blood vessels remain open and relaxed.
Alpha blockers can treat a small range of diseases such as hypertension, Raynaud's disease, benign prostatic hyperplasia (BPH) and erectile dysfunction. [2] Generally speaking, these treatments function by binding an α-blocker to α receptors in the arteries and smooth muscle.
13 Jun 2023 · Alpha-blockers work by blocking the transmission of certain nerve impulses. The ends of some nerves release a chemical (neurotransmitter) called noradrenaline (norepinephrine) when the nerve is stimulated.
6 Mei 2024 · Alpha blockers bind to and block alpha-1 receptors. They are mostly used to treat high blood pressure or symptomatic benign prostatic hypertrophy (BPH) because alpha-1 receptors are located in the smooth muscle lining blood vessels, in the prostate, and in the neck of the bladder.
3 Mei 2024 · Alpha blockers work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins. This allows vessels to remain open and relaxed to improve blood flow and lower blood pressure.
3 Jul 2023 · Alpha-blockers are medications used in the management and treatment of essential hypertension, benign prostatic hyperplasia (BPH), and pheochromocytoma.
10 Mac 2022 · 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).
Alpha-blockers are a type of medicine that can be used to treat high blood pressure. They work by allowing the blood vessels to relax and widen, so the blood has more space to flow through. They include doxazosin, indoramin, prazosin, and terazosin. How do alpha-blockers work?
Alpha-blockers used in treating essential hypertension are all highly selective for α 1 -adrenoceptors. Non-selective blockers are used during hypertensive crisis caused by elevated circulating catecholamines (pheochromocytoma). The following table compares different alpha-blockers that are presently used in patients.
