From the Guidelines
For patients with a brain bleed, immediate blood pressure lowering is not recommended for patients with systolic BP <220 mmHg, but careful acute BP lowering with i.v. therapy to <180 mmHg should be considered in patients with systolic BP ≥220 mmHg. When managing blood pressure in patients with acute intracerebral haemorrhage, it is crucial to consider the severity of the hypertension 1. The following key points should be considered:
- In patients with systolic BP ≥220 mmHg, careful acute BP lowering with i.v. therapy to <180 mmHg should be considered 1.
- First-line medications for severe hypertension include i.v. labetalol, oral methyldopa, or nifedipine 1.
- Intravenous hydralazine is a second-line option for severe hypertension 1. It is essential to balance the risk of hematoma expansion (from high blood pressure) against the risk of cerebral ischemia (from low blood pressure), and frequent neurological assessments are necessary during treatment 1. Key considerations for blood pressure management in brain bleed patients include:
- Cautious lowering of blood pressure to prevent cerebral hypoperfusion
- Avoiding excessive cerebral vasodilation
- Frequent neurological assessments to monitor for worsening brain injury
- Balancing the risk of hematoma expansion against the risk of cerebral ischemia 1.
From the FDA Drug Label
2 DOSAGE & ADMINISTRATION
- 1 General Information Individualize dosing based on the severity of hypertension and the response of the patient during dosing. Monitor blood pressure and heart rate both during and after the infusion to avoid tachycardia or too rapid or excessive reduction in either systolic or diastolic blood pressure Administer Nicardipine Hydrochloride by slow continuous infusion by a central line or through a large peripheral vein.
Nicardipine can be used as an antihypertensive medication in the setting of a brain bleed.
- The dosage should be individualized based on the severity of hypertension and the patient's response.
- It is essential to monitor blood pressure and heart rate during and after the infusion to avoid excessive reduction in blood pressure.
- The medication should be administered by slow continuous infusion, either through a central line or a large peripheral vein 2.
From the Research
Antihypertensive Medication for Brain Bleed
- The use of antihypertensive medication in the management of brain bleed, specifically intracerebral hemorrhage (ICH), has been studied in several research papers 3, 4, 5, 6, 7.
- Clevidipine has been shown to rapidly and safely reduce blood pressure in acute ICH patients, with minimal hematoma expansion 3.
- Nicardipine has also been found to be effective in reducing blood pressure in ICH patients, with similar efficacy to clevidipine 5.
- A systematic review and individual participant data analysis found that intensive blood pressure lowering with nicardipine was associated with lower risks of hematoma expansion and 90-day death or disability 6.
- The acute management of hypertension following ICH is crucial, and rapidly reducing blood pressure has been found to be safe in certain patient populations 7.
Comparison of Antihypertensive Medications
- A study comparing clevidipine and nicardipine found no significant difference in time to goal systolic blood pressure (SBP) reduction, but nicardipine had a lower cost and less rebound hypertension 5.
- Another study found that rapid lowering of SBP by continuous administration of intravenous nicardipine was associated with lower risks of hematoma expansion and 90-day death or disability 6.
Safety and Efficacy
- Clevidipine has been shown to be effective and safe for rapid blood pressure reduction in ICH patients, with minimal hematoma expansion 3.
- Nicardipine has also been found to be safe and effective in reducing blood pressure in ICH patients, with minimal serious adverse events 6.
- The use of antihypertensive medication in the management of brain bleed requires careful consideration of the potential benefits and risks, and should be individualized to each patient's specific needs 7.
