Oral nifedipine in hypertensive emergencies

Area of Science:

• Cardiology
• Pharmacology

Background:

• Hypertensive emergencies require prompt blood pressure reduction.
• Parenteral therapies are common but may have drawbacks.

Purpose of the Study:

• To evaluate the efficacy and tolerance of oral nifedipine in managing hypertensive emergencies.
• To assess the safety profile of oral nifedipine in this patient group.

Main Methods:

• Eleven patients with hypertensive emergencies received oral nifedipine (10 mg) every 6 hours.
• Blood pressure, pulse, and blood chemistry were monitored.
• Efficacy was assessed by blood pressure reduction over time.

Main Results:

• Significant blood pressure reduction observed within 30 minutes, peaking at 90 minutes.
• Maximum systolic blood pressure reduction was 20.78%, diastolic 21.74%.
• No significant changes in pulse rate or blood chemistry; no side-effects reported.

Conclusions:

• Oral nifedipine is a simple, effective, and well-tolerated treatment for hypertensive emergencies.
• It offers a viable alternative to intravenous medications.
• Further research may support its broader use in clinical practice.
