Dopamine: Class, Trade name, Action, uses and dosages
- Class: sympathomimetic
- Trade name: Intropin
- Actions: naturally occurring neurotransmitter and immediate precursor of norepinephrine. Major cardiovascular effects are produced by direct action on alpha and beta adrenergic receptors and on specific dopaminergic receptors in mesenteric & renal vascular beds. Positive inotrpoic effect on mycardium increases cardiac output w/increase in systolic and pulse pressure and little effect on diastolic. Decreases renal vascular resistance which increases glomerular filtration rate and urinary output.
- Uses: increase end organ perfusion in cardiogenic shock & in hemodynamically significant hypotension
- Dose: Adult/Ped- 2 to 20 mcg/kg/min titrated to effect
