Nifedipine vs nicardipine for cerebral vasodilating and cerebral blood flow? the literature says nicardipine but it's not prescribed often right?

Nicardipine: These two meds are from the same class. Both vasodilate arteries and arterioles, both drop blood pressure, both are designed to have little or minimal effect on myocardial muscle contraction and cardiac conduction systems. Mg vs mg, nicardipine is slightly more potent in these vasodilating actions. The formulations account for this difference, as hypotension is the chief risk and hazard.
