Which IV antihypertensive agent has a titration protocol starting at 5 mg/hr with increments of 2/5 mg/hr every 5-15 minutes up to a max of 15 mg/hr?

Which IV antihypertensive agent has a titration protocol starting at 5 mg/hr with increments of 2/5 mg/hr every 5-15 minutes up to a max of 15 mg/hr?

• A. Labetalol
• B. Nicardipine
• C. Clevidipine
• D. Hydralazine

Answer: (B)

The key idea here is recognizing which IV antihypertensive uses a controlled, stepwise titration that starts at 5 mg/hour and increases by 2.5 mg/hour every 5–15 minutes up to a maximum of 15 mg/hour. This exact protocol is characteristic of nicardipine, a calcium channel blocker used intravenously to lower blood pressure in acute settings with careful, incremental adjustments. The gradual increments allow precise BP control and help avoid overshoot, which is crucial when managing blood pressure in patients with stroke to preserve cerebral perfusion. Other agents have different titration patterns: one is typically started with a bolus or a different infusion rate and adjusted in smaller, more frequent increments or by different timing; another is given as intermittent boluses rather than a continuous, steadily titrating infusion; and yet another relies on bolus dosing without the same stepwise infusion plan. These contrasts make the described protocol a hallmark of nicardipine.
