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,…
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…
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…
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…
Phenoxybenzamine is a non-selective, irreversible alpha-adrenergic receptor antagonist primarily used in conditions associated with excess catecholamine activity. It belongs to the class of haloalkylamine derivatives and plays a crucial role in managing hypertension associated with adrenal tumors, particularly pheochromocytoma. Unlike many other adrenergic blockers, phenoxybenzamine forms a covalent bond with alpha receptors, leading to long-lasting…
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…
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…
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…
Filtration is the process wherein a filter medium separates a heterogeneous mixture of fluid and solid particles. The filter medium allows the passage of fluid but retains the solid particles. The process retains oversized solids in the fluid, but it does not complete the separation, as the filtrate may contaminate with solid particles smaller in…
A triple roller mill is used to mix semisolids while preparing ointments, creams, pill masses, wet mass for making granules, etc. Principle The material experiences a high shear developed by the differential speed and the narrow space between the rollers. Under the influence of this shear, aggregates, and particles get crushed, and the drug gets…
