Efficacy and safety of felodipine, a new dihydropyridine calcium channel blocker, in elderly hypertensive patients.
Felodipine is a new dihydropyridine calcium channel blocker with a number of properties that enhance its suitability as a first-line antihypertensive drug for the elderly. Felodipine has a 100-fold selectivity for inhibiting the contribution of vascular smooth muscle compared with cardiac muscle. Negative inotropic action appears minimal while selectivity appears to increase with age. Felodipine has a minimal effect on smooth muscle of venous capacitance vessels, thereby greatly reducing the likelihood of orthostatic hypotension. Renal effects are favorable; the glomerular filtration rate is increased in some patients. The extended-release formulation of felodipine produces a smooth 24-hour plasma concentration curve and is effective when prescribed once daily. Felodipine appears to lower blood pressure effectively in the elderly patient with few, generally mild, adverse effects.
