aka sympathomimetic drugs- they mimic the effects of the sympathetic nervous system (SNS)

related to their stimulation of adrenergic receptor sites

varies from ophthalmic preparations for dilating pupils to systemic preparations for shock

epinephrine, norepinephrine, dopamine, dobutamine, ephedrine, ephedrine,

(adrenalin) treats shock, glaucoma; prolongs effects of regional anesthetic.  this is the main drug used; usually given as a shot for allergic reaction

(levophed) treats shock or is used during cardiac arrest to stimulate sympathetic activity

(intropin) treats shock; increases the effectiveness of heart; doesnt need more oxygen; used more now than norepinephrine

(dobutrex) treats congestive heart failure

(pretz-d) treats seasonal rhinitis

Alpha and Beta Adrenergic agonists

(actions)

effects are mediated by the adrenergic receptors in target organs; heart rate increases, bronchi dilate, vasoconstriction occurs, intraocular pressure decreases, and glycogenolysis occur throughout the body

treatment of hypotensive shock, bronchospasm, and some types of asthma

rapidly absorbed after injection or passage through mucous membranes

metabolized in the liver and excreted in the urine

given IV, IM, nasal spray
