Felodipine can replace minoxidil in the treatment of refractory hypertension.

In a group of 15 men with severe hypertension in a double-blind crossover trial, the new calcium antagonist felodipine has been shown to lower blood pressure as effectively as minoxidil when used in combination with a beta-blocker and a loop diuretic. Felodipine was well tolerated and may have a role in the management of severe hypertension.
