Nifedipine: two new uses.
Nifedipine, a calcium channel blocker currently indicated for vasospastic and chronic stable angina, undoubtedly will have many other uses because of its potent peripheral vasodilatory activity and minimal effects on cardiac contractility. These effects of the drug have proved beneficial in treatment of malignant hypertension and Raynaud's phenomenon. Single oral doses of nifedipine 10-20 mg have rapidly and smoothly reduced blood pressure in malignant hypertension, suggesting its use in the emergency room or office setting. Continuous monitoring of the patient is not required. Studies also have demonstrated the efficacy of nifedipine in Raynaud's phenomenon, and the drug should be considered as an initial agent of choice.
