Guanadrel Sulfate is a postganglionic adrenergic blocking agent. The uptake of guanadrel and storage in sympathetic neurons occurs via the norepinephrine pump or transporter.
Norepinephrine bitartrate is a precursor of epinephrine. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus.
Azelnidipine, (S)-, is an L-type calcium channel blocker (CCB). Studies have shown that in patients with hypertension (HT) and heart failure preserved ejection fraction (HFpEF), azelnidipine improved the severity of HF and cardiac sympathetic nerve activity compared with cilnidipine, an N-type CCB (Cat#326734).
Trimetaphan camsilate is a drug that counteracts cholinergic transmission at the ganglion type of nicotinic receptors of the autonomic ganglia and therefore blocks both the sympathetic nervous system and the parasympathetic nervous system. It acts as a non-depolarizing competitive antagonist at the nicotinic acetylcholine receptor, is short-acting, and is given intravenously.
Hexamethonium monotartrate is a non-depolarizing NMJ blocker and nAChR antagonist. It has previously been used to treat hypertension. It inhibits sympathetic nervous system activity and acts as a skeletal muscle relaxant.
Hexamethonium bromide dihydrate is a non-depolarizing NMJ blocker and nAChR antagonist. It has previously been used to treat hypertension. It inhibits sympathetic nervous system activity and acts as a skeletal muscle relaxant.
Ephedrine levulinate is an alkaloid. Ephedrine acts as an agonist at alpha- and beta-adrenergic receptors and indirectly causes the release of norepinephrine from sympathetic neurons.
