Abstract

Felodipine, a new dihydropyridine derivative with a selective action on vascular smooth muscle, was investigated in 2 short term studies in hypertensive patients. In the first study, oral administration of felodipine 12.5 mg three times daily in a preliminary tablet formulation for 3 days significantly reduced supine and upright blood pressure with only a slight increase in heart rate and no clinically relevant signs of sodium and water retention. By increasing each dose to 25 and 50 mg three times daily, there was a further, but quite moderate, decrease in blood pressure; however, this was accompanied by an increase in heart rate and a tendency towards a reduction of creatinine clearance and urinary sodium output. In the second study, a new oral formulation containing 10 mg felodipine, administered twice daily for 7 days, was effective in lowering blood pressure without a clinically relevant tachycardia. Following the first dose of felodipine, urinary sodium excretion was slightly increased while potassium excretion showed only minor changes. The new calcium antagonist, felodipine, lowers blood pressure without the clinically relevant adverse reactions commonly related to other direct vasodilator antihypertensive drugs
