*adrenergic drugs Flashcards
what do adrenergic drugs do to sympathetic nervous system
stimulate
examples of catecholamines
norepinephrine, epinephrine, dopamine
where are B1 receptors
the heart
where are B2 receptors
the lungs
what are the drug examples for vasoactive sympathomimetics
pressers and inotropes
dobutamine mechanism of action/drug class
selective vasoactive B1 drug to stimulate the heart muscle
what receptors does dopamine act on
B1 and A1
what is the therapeutic effect of dopamine on the body
low dose: dilates blood vessels to primary organs to increase blood flow, improves cardiac contractility. high dose: vasoconstriction
what receptors does epinephrine effect and what happens when the receptors are stimulated
A and B (nonselective) causes vasoconstriction, stimulates the heart
what does epinephrine treat
hypotension, shock, anaphylaxis
what conditions does phenylephrine treat
supraventricular dysthymias, nasal decongestion
