Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines) are stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Examples of sympathomimetic effects include increases in heart rate , force of cardiac contraction , and blood pressure . [ 1 ]
A sympatholytic (sympathoplegic) drug is a medication that opposes the downstream effects of postganglionic nerve firing in effector organs innervated by the sympathetic nervous system (SNS). [1] They are indicated for various functions; for example, they may be used as antihypertensives .
These drugs mimic sympathetic stimulation and increase cardiac output. Anagrelide [24] Cilostazol is used in the treatment of intermittent claudication. Pimobendan is FDA approved for veterinary use in the treatment of heart failure in animals. PDE3 is sometimes referred to as cGMP-inhibited phosphodiesterase.
Alpha adrenoreceptor ligands mimic the action of epinephrine and norepinephrine signaling in the heart, smooth muscle and central nervous system, with norepinephrine being the highest affinity. The activation of α 1 stimulates the membrane bound enzyme phospholipase C , and activation of α 2 inhibits the enzyme adenylate cyclase .
Autonomic drugs are substances that can either inhibit or enhance the functions of the parasympathetic and sympathetic nervous systems. This type of drug can be used to treat a wide range of diseases an disorders, including glaucoma , asthma , and disorders of the urinary , gastrointestinal and circulatory systems.
Overproduction of certain kinds of white blood cells that produce hormones and other factors that mimic or activate your body’s sympathetic nervous system to give you the sensation of chills ...
In general, pure beta-adrenergic agonists have the opposite function of beta blockers: beta-adrenoreceptor agonist ligands mimic the actions of both epinephrine- and norepinephrine- signaling, in the heart and lungs, and in smooth muscle tissue; epinephrine expresses the higher affinity.
Semaglutide is the active ingredient in Ozempic and Wegovy. These drugs mimic GLP-1 — the hormone the body naturally produces after eating — to make people feel full, reducing their cravings. ...
