Carvedilol: Mechanism of Action, Uses, Side Effects, Stability, and Storage

by

Carvedilol is a pharmaceutical agent classified as a non-selective beta-blocker and alpha-1 blocker. Healthcare providers use it in the treatment of various cardiovascular conditions, primarily heart failure and hypertension.Carvedilol exerts its therapeutic effects by blocking both beta receptors in the heart (particularly beta-1 receptors) and alpha-1 receptors in blood vessels. This dual mechanism of action … Read more

Atenolol: Mechanism of Action, Uses, Side Effects, Stability, and Storage

by

Atenolol is a medication that belongs to the class of drugs known as beta-blockers. It is commonly prescribed for the treatment of cardiovascular conditions, particularly hypertension (high blood pressure) and angina (chest pain). Atenolol works by selectively blocking beta-1 adrenergic receptors in the heart. Doing so reduces the effects of adrenaline and other stress hormones, … Read more

Propranolol: Mechanism, Uses, Side effects

by

Propranolol is a medication belonging to the class of drugs known as beta-adrenergic blockers. It is a non-selective beta blocker, which blocks beta-1 (β1) and beta-2 (β2) adrenergic receptors. Propranolol affects receptors primarily found in the heart, blood vessels, and lungs. Healthcare providers use it for various cardiovascular and non-cardiovascular conditions because it blocks the … Read more

Beta-adrenergic blockers

by

Beta-adrenergic blockers, often simply referred to as beta blockers, are a class of medications that block the effects of adrenaline (epinephrine) and related hormones. These drugs primarily target beta-adrenergic receptors, which are found in various tissues, including the heart, blood vessels, and certain parts of the nervous system. Beta-blockers exert a range of effects on … Read more

Prazosin: Mechanism, Uses, Side effects

by

Prazosin is a medication classified as an alpha-1 adrenergic blocker. It belongs to the class of drugs known as alpha-adrenergic antagonists. Prazosin primarily acts on alpha-1 receptors, blocking the effects of norepinephrine and leading to vasodilation and relaxation of smooth muscle in blood vessels. Here are key points about prazosin: Mechanism of Action Prazosin selectively … Read more

Phenoxybenzamine: Mechanism, Uses, Side effects

by

Phenoxybenzamine is a medication classified as an alpha-adrenergic antagonist, specifically an irreversible alpha-blocker. It is used primarily to treat conditions associated with excessive sympathetic nervous system activity, such as pheochromocytoma, a rare adrenal tumor that releases high levels of catecholamines, leading to severe hypertension. Here are key points about phenoxybenzamine: Mechanism of Action Phenoxybenzamine irreversibly … Read more

Phentolamine: Mechanism, Uses, Side effects

by

Phentolamine is a medication classified as an alpha-adrenergic antagonist, specifically an alpha-blocker. It acts by blocking the effects of norepinephrine and other similar neurotransmitters at alpha-adrenergic receptors. Phentolamine is a non-selective alpha-blocker, meaning it blocks both alpha-1 and alpha-2 receptors. Here are key points about phentolamine: 1. Mechanism of Action Phentolamine blocks the action of … Read more

Tolazoline: Mechanism, Uses, Side effects

by

Tolazoline is a medication that belongs to the class of drugs known as alpha-adrenergic blockers. It is primarily used as a vasodilator, which relaxes and widens blood vessels. This vasodilatory effect is attributed to its ability to block alpha-adrenergic receptors. Here are some key points about tolazoline: Mechanism of Action Tolazoline acts as a non-selective … Read more

Adrenergic antagonists/adrenergic blockers/adrenergic receptor antagonists

by

Adrenergic antagonists, also known as adrenergic blockers or adrenergic receptor antagonists, are a class of drugs that interfere with the actions of the sympathetic nervous system, specifically by blocking the effects of neurotransmitters like norepinephrine and epinephrine (adrenaline) at adrenergic receptors. These receptors are found throughout the body and are crucial in regulating various physiological … Read more

Metaraminol-Definition, Uses, Side effects

by

Metaraminol, a sympathomimetic amine and vasopressor medication, primarily treats low blood pressure (hypotension) in various clinical situations, such as during surgery, shock, or certain medical conditions. Uses 1. Vasopressor: Doctors primarily use metaraminol as a vasopressor to treat hypotension (low blood pressure) in various clinical situations, including surgery, trauma, septic shock, or other medical conditions. … Read more
