Mid-range dose (4-10mcg): Stimulates beta receptors to increase
contractility and heart rate
High range dose (greater than 10mcg): Stimulates alpha receptors -
vasoconstriction and increase in BP
Side effects:
- Ventricular dysrhythmias
- Tachycardia
- Infiltration = necrosis (Vasoconstriction of capillary beds)
Antidote: regitine (phentolamine) - same for levophed necrosis
