Adrenergic agonists are a group of drugs that stimulate alpha and beta adrenergic receptors by mimicking the action of naturally occurring catecholamines such as norepinephrine, epinephrine and dopamine. This pharmacology lecture covers topics such as mechanism of action of adrenergic agonists; catecholamines, noncatecholamines, direct acting, indirect acting, mixed action; location and function of alpha and beta receptors. Adrenergic agonists mentioned include: Epinephrine, Norepinephrine, Dopamine, Oxymetazoline, Phenylephrine, Clonidine, Dobutamine, Albuterol, Terbutaline, Salmeterol, Formoterol, Mirabegron, Cocaine, Amphetamine, Ephedrine, Pseudoephedrine.

There seems to be some questions regarding alpha-1 stimulation in the kidney, and I might have made a mistake. Alpha-1 receptor stimulation in the kidney does not directly cause the inhibition of renin release. Instead, it indirectly leads to renin release. Alpha-1 receptor activation causes vasoconstriction in renal blood vessels, which reduces renal blood flow and glomerular filtration rate (GFR). The decrease in GFR triggers a compensatory response that includes an increase in renin secretion. So, alpha-1 receptor stimulation ultimately promotes, rather than inhibits, renin release in the kidney.

As much as i know and have researched thoroughly about,(please correct me if i am wrong)Alpha 1 adrenergic receptors are not found on kidney to reduce renin release.Beta 1 however are present on JG apparatus to increase renin release because in fight or flight situation u need RAAS to constrict ur blood vessels and aldosterone to retain water and salts in case you bleed.Alpha 1 are however found on blood vessels going to kidney to constrict them so less urine is formed in emergency situation.Overall good video.thank you so much

Wow this is an amazing video, it helps me to study for my exam. But, can I ask you a question? You said that beta 2 receptor is responsible in increasing insulin... but from what I know that it's increasing glucagon level instead. And that's why beta blockers can be causing hypoglycemia. Can you explain it? In other word, is salbutamol or formoterol can cause hypoglycemia?

@SpeedPharmacology 5 жыл бұрын

Beta-2 adrenergic agonists can cause insulin release from the pancreas, and at the same time they can also stimulate glycogenolysis in the liver, which can lead to hyperglycemia.
