Dobutamine is a direct-acting agent whose primary activity results from stimulation of the β 1-adrenoceptors of the heart, increasing contractility and cardiac output. Since it does not act on dopamine receptors to inhibit the release of norepinephrine (another α 1 agonist), dobutamine is less prone to induce hypertension than is dopamine.
“Individuals, if they have their own history of having high blood pressure measurement, or a strong family history of high blood pressure, or, finally, cardiovascular risk factors—things like ...
Dopamine, sold under the brand name Intropin among others, is a medication most commonly used in the treatment of very low blood pressure, a slow heart rate that is causing symptoms, and, if epinephrine is not available, cardiac arrest. [4] In newborn babies it continues to be the preferred treatment for very low blood pressure. [5]
Rilmenidine, an oxazoline compound with antihypertensive properties, acts on both medullary and peripheral vasomotor structures.. Rilmenidine is a imidazoline analog and shows greater selectivity for imidazoline receptors than for cerebral alpha2-adrenergic receptors, distinguishing it from reference alpha2-agonists, and conferring additional anti-inflammatory actions not shared with most ...
Pemoline has been used in the treatment of ADHD and narcolepsy. [2] [1] [5] It has also been used in the treatment of excessive daytime sleepiness. [8]The medication was typically used at doses of 18.75 to 112.5 mg once per day in the treatment of ADHD, with the effective dose for most people being in the range of 56.25 to 75 mg. [1] [2] The onset of action of pemoline is gradual and ...

Trimetaphan camsilate or trimethaphan camsylate (), trade name Arfonad, is a sympatholytic drug used in rare circumstances to lower blood pressure.. Trimetaphan is a ganglionic blocker: it counteracts cholinergic transmission at a specific type of nicotinic acetylcholine receptors in the autonomic ganglia and therefore blocks both the sympathetic nervous system and the parasympathetic nervous ...
The primary application for phentolamine is for the control of hypertensive emergencies, most notably due to pheochromocytoma. [5]It also has usefulness in the treatment of cocaine-induced cardiovascular complications, where one would generally avoid β-blockers (e.g. metoprolol), as they can cause unopposed α-adrenergic mediated coronary vasoconstriction, worsening myocardial ischemia and ...
