Dobutamine Mechanism of action

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

On set IV

1-10 min
Dobutamine pharmacodynamics

Peak effect

10-20 min
Dobutamine pharmacodynamics

half-life elimination

2 min
Dobutamine Adverse reaction

Cardiovascular
- Increase HR
- increased BP
- increased ventricular ectopic activity
- hypotension
- PVC
- Palpitation
Dobutamine Adverse reaction

Respiratory and Neuro Musc

Dyspnea and Mild leg cramps
Dobutamine Hemodynamic effects

2-10 mcg/kg/min
Dopamine Mechanism of Action

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
Dopamine Adverse reaction

Cardiovascular
- Ectopic Beats,
- Tachycardia
- anginal
- palpitation
- hypotension
- vasoconstritions
Dopamine Adverse reaction

CNS
GI
