IV Direct:
- 0.2-1 mg/kg/dose IV every 10 minutes as needed
- Maximum: 40 mg/dose
Continuous IV infusion:
- Initial: 0.25 - 1 mg/kg/hour
- Titrate by increments of 0.25 to 0.5 mg/kg/hour as needed to control BP
- Maximum: 3 mg/kg/hour (rates up to 8 mg/hour have been used)
Acute Ischemic Stroke (BP management with reperfusion therapy)
IV Direct:
- 0.5 mg/kg/dose IV every 10 minutes as needed to maintain systolic blood pressure within target
- Maximum: 40 mg/dose
- After 3 doses have been given and desired BP is not achieved, switch to continuous infusion
Continuous Infusion:
- Initial: 0.5-1 mg/kg/hour
- Titrate by increments of 0.5 mg/kg/hour every 10 minutes to maintain systolic blood pressure within target
- Maximum: 3 mg/kg/hour (rates up to 8 mg/hour have been used)

- Somnolence, vertigo
- Contraindicated in asthma, obstructive airway disease, greater than first degree heart block, cardiogenic shock, severe bradycardia, uncontrolled CHF, pulmonary edema
- Caution in patients with diabetes mellitus (masks signs of hypoglycemia), impaired hepatic function (metabolized in liver) and pheochromocytoma (paradoxical hypertensive responses)
- Additive hypotensive response may occur with halothane or isoflurane anesthesia
- Patients should remain supine during and for up to three hours after IV administration
- Monitor blood pressure, heart rate, pulse, EKG
- Onset: 2-5 minutes; duration: 2-4 hours
