Usual Adult Dose for Hypertensive Emergency

0.01 to 0.3 mcg/kg/min IV as a continuous infusion; may increase by 0.05 to 0.1 mcg/kg/min every 15 minutes or longer until target blood pressure is reached.

Maximum dose: 1.6 mcg/kg/min

Duration of therapy: Maintenance infusions may be continued for up to 48 hours.

Comments:

• Doses lower than 0.1 mcg/kg/min and slow up-titration have been associated with less reflex tachycardia.
• Oral antihypertensives can be added any time after blood pressure is stable during infusion of this drug.

Use: In-hospital, short-term management of severe hypertension when rapid, but quickly reversible, emergency reduction of blood pressure is clinically indicated, including malignant hypertension with deteriorating end-organ function.

Usual Pediatric Dose for Hypertensive Emergency

Less than 1 month (at least 2 kg or full term) to 12 years:
0.2 mcg/kg/min IV as a continuous infusion; may increase by 0.3 to 0.5 mcg/kg/min every 20 to 30 minutes to maximum dose

Maximum dose: 0.8 mcg/kg/min

Duration of therapy: Maintenance infusions may be continued for up to 4 hours.

Comments: In general, doses greater than 0.8 mcg/kg/min produced no further decreases in mean arterial pressure (MAP) but did worsen tachycardia.
