stimulates B1 adrenergic crecptors, causing increased contractility and herat rate w/ little effect on B2 or Alpha receptors

1-10 min

• Increase HR
• increased BP
• increased ventricular ectopic activity
• hypotension
• PVC
• Palpitation

Dyspnea and Mild leg cramps

2-10 mcg/kg/min

Stimulates both adrenergic and dopaminergic receptors, lower doses are mainly dopaminergic stimulating  and produce renal and mesenteric vasodilation,

 higher doses also are both dopaminergic and B1 adrenergic stimulating and produc cardiac stimulation and renal vasodilation; Large doses stimulate Alpha receptors

• Ectopic Beats,
• Tachycardia
• anginal
• palpitation
• hypotension
• vasoconstritions
