Finally, in drugs with both alpha and beta blocking properties, such as carvedilol and labetalol, interactions with other alpha or beta blockers can exaggerate a decrease in blood pressure. [2] Conversely, there are also drug interactions with carvedilol or labetalol in which blood pressure is increased unintentionally (such as with cough and ...
Those that block beta-2-adrenergic receptors reduce blood pressure through increased relaxation of smooth muscle. [33] Alpha-blockers can block alpha-1 adrenergic receptors and/or alpha-2 adrenergic receptors. [34] Those that block alpha-1-adrenergic receptors on vascular smooth muscle cells prevent vasoconstriction. [34]
First generation alpha-1 blockers, like prazosin are not recommended to treat lower urinary tract symptoms because of their blood-pressure-lowering effect. Later generation drugs in this class are used for this purpose. [1] [9] In some cases alpha-1 blockers have been used in combined therapy with 5α-reductase inhibitors.
Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD. [2]
For most people, recommendations are to reduce blood pressure to less than or equal to somewhere between 140/90 mmHg and 160/100 mmHg. [2] In general, for people with elevated blood pressure, attempting to achieve lower levels of blood pressure than the recommended 140/90 mmHg will create more harm than benefits, [3] in particular for older people.

Sleep is essential when managing or trying to ward off high blood pressure. A 2024 study linked getting too few hours of shut-eye with high blood pressure. However, some blood pressure medications ...
As alpha 1 blocker will dilate blood vessels, it lowers the blood pressure. [3] Thus, it contraindicate to patients with a history of orthostatic hypotension and in current use of phosphodiesterase inhibitors. [3] Moreover, alpha 1 blocker should not be given to patients with heart failure since it expands blood volume. [13]
Carvedilol is a nonselective beta blocker and alpha-1 blocker. [5] How it improves outcomes is not entirely clear but may involve dilation of blood vessels. [5] Carvedilol was patented in 1978 and approved for medical use in the United States in 1995. [5] [8] It is on the World Health Organization's List of Essential Medicines. [9]
