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.
An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance.This is different from inotropes which increase the force of cardiac contraction.
The main discussion of these abbreviations in the context of drug prescriptions and other medical prescriptions is at List of abbreviations used in medical prescriptions. Some of these abbreviations are best not used, as marked and explained here.
This is a list of abbreviations used in medical prescriptions, including hospital orders (the patient-directed part of which is referred to as sig codes).This list does not include abbreviations for pharmaceuticals or drug name suffixes such as CD, CR, ER, XT (See Time release technology § List of abbreviations for those).
Sympathomimetic drugs are used to treat cardiac arrest and low blood pressure, or even delay premature labor, among other things. These drugs can act through several mechanisms, such as directly activating postsynaptic receptors, blocking breakdown and reuptake of certain neurotransmitters, or stimulating production and release of catecholamines.
Some foods, on the other hand, increase dopamine production in the brain through levodopa, an amino acid that’s part of the chemical reaction that makes dopamine, says Candace Pumper, RD, a ...
Naturally produced hormones norepinephrine and epinephrine or synthetic drugs such as dobutamine can be collectively regarded as beta-agonists. Specifically, dobutamine selectively binds to β1 receptors located on the surface of specialised cardiac muscle cells. [ 16 ]
Humphreys noted that alcohol is, in essence, a drug, and people should take that into consideration when deciding how much to drink. “Take alcohol seriously as a drug with risks.
