adrenalin is an agonist
adrenergic receptor
Cholinergic
Epinephrine or more commonly known as adrenaline bind to adrenergic receptors. These adrenergic receptors are a type of G-protein coupled receptors
epinephrine and norpepinephrine
Epinephrine and norepinephrine are two very structurally similar molecules. They've both involved in the sympathetic part of your autonomic nervous system. Epinephrine (also known as adrenaline) is a hormone which is secreted from the adrenal medulla when activated by the sympathetic nervous system (during times of stress). Norepinephrine (also known as noradrenaline) is a neurotransmitter that is released by neurons in the sympathetic nervous system. Epinephrine and norepinephrine generally produce the same effects as they both interact with adrenergic receptors in the body. Epinephrine is structurally different from norepinephrine as epinephrine has a methyl group (-CH3) attached to the nitrogen atom (making it a secondary amine), whereas norepinephrine is just a primary amine.

Epinephrine or adrenaline, and non epinephrine or noradrenaline.

The alpha adrenergic receptors are located in the effector organs of sympathetic nervous system. They are the most common type of alpha adrenergic receptor. Alpha adrenergic receptors tend to be excitatory. They have a greater affinity for nonepinephrine than epinephrine.
Antiadrenergic drugs decrease or block effects of sympathetic nerve stimulation, endogenous catecholamines (e.g. epinephrine), and adrenergic drugs.
Tizanidine- drug that is used as a muscle relaxant and α2-adrenergic agonist. Nowhere in the intruxions says where it cames from.
Beta adrenergic agents serve as inhibitors that prevent beta adrenergic substances (neurotransmitters) such as epinephrine from binding to beta adrenergic receptors (beta 1, beta 2 and beta 3). This prevents the effects of the neurotransmitters thereby reducing blood pressure and heart rate.
Beta 2 adrenergic agonists cause increased potassium entry into cells, which can lead to hypokalemia
No. Muscarinic receptors are affected by acetylcholinergic neurotransmitters (ie. muscarine, atropine). Only the parasympathetic nervous system have muscarinic receptors. Epinephrine affects adrenergic receptors (symapthetic nervous system).
Clonidine is a central alpha 2 agonist. Alpha 2 agonists relax GI smooth muscle. With relaxation of the lower esophageal sphincter (LES), reflux of stomach contents is more likely to occur.
