Used for diagnosis of too much catecholamines
Urine matabolites: vanillylmandelic acid, metanephrine, normetanephrine
Inhibits reuptake of catecholamines
Cocaine, TCA
Promotes release of cathecolamines from presynapse
Amphetamine, methamphetamine, ephedrine, tyramine, pseudoephedrine
Inhibits release of cathecolamines
Guanethidine, bretylium
Ion that Causes release of NE
Calcium
Alpha 1 receptors
Blood vessels (vasoconstriction), pili erector muscles(contrac), pupils (mydriasis), sphincters GIT/GUT(closed)
Alpha 2
Presynaptic (modulates NE, decrease cathecolamine release), postsynaptic( relax smooth muscles, vasoconstric)
Beta 1
Heart increase rate, kidney (renin release)
Beta 2
Bronchus (dilation), skeletal muscles (contract), uterus (relax), pancrease (insulin release), metabolism ( glucogenesis)
Beta 3
Adipose tissue (lipolysis)
Dopamine 1
Blood vessels of renal, mesenteric, coronary (vasodilation therfore increase blood flow in kidney)
Dopamine 2
Cns
Types of adrenergic agonist
Catecholamines and noncatecholamines
Catecholamines with __ groups, __ metabolism, __ polarity
Catechol or 3,4-dihydroxybenzene group, COMT AND MAO metabolism, polar therefore difficult to penetrate CNS
Non-catecholamine, __ metabolism, __ polarity
Decrease metab therefore longer half life, increase lipid solubility therefore non polar
DOC: bronchospasm
