A drug stimulating a receptor for norepinephrine or epinephrine is called: Adrenergic. A drug blocking a receptor for Acetylcholine is called. Anticholinergic. WebIt has been hypothesized that epinephrine stimulates prejunctional beta 2-adrenergic receptors to facilitate NE release from sympathetic nerve endings, and therefore, presynaptic receptors controlling NE release are potential therapeutic targets to limit the adverse effects of excess sympathetic stimulation during anesthesia.
WebMar 14, 2024 · The release of epinephrine is stimulated by sympathetic activation, which occurs during stress. Epinephrine will then travel to the liver, where it will bind to β-adrenergic receptors. This will stimulate glycogenolysis, which increases the blood glucose level. Epinephrine will also act on other tissues:
