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 ...
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]
Alpha-1 blockers (also called alpha-adrenergic blocking agents or alpha-1 antagonists) constitute a variety of drugs that block the effect of catecholamines on alpha-1-adrenergic receptors. They are mainly used to treat benign prostatic hyperplasia (BPH), hypertension and post-traumatic stress disorder . [ 1 ]
Central alpha agonists lower blood pressure by stimulating alpha-receptors in the brain which open peripheral arteries easing blood flow. These alpha 2 receptors are known as autoreceptors which provide negative feedback in neurotransmission (in this case, the vasoconstriction effects of adrenaline). Central alpha agonists, such as clonidine ...
The following are medications commonly prescribed cardiac pharmaceutical agents. The specificity of the following medications is highly variable, and often are not particularly specific to a given class. As such, they are listed as are commonly accepted.
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.
Moxonidine is a new-generation alpha-2/imidazoline receptor agonist antihypertensive drug licensed for the treatment of mild to moderate essential hypertension. [5] [6] It may have a role when thiazides, beta-blockers, ACE inhibitors, and calcium channel blockers are not appropriate or have failed to control blood pressure.
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.
