The pharmacodynamics and pharmacokinetics of a new calcium antagonist nisoldipine in normotensive and hypertensive subjects.

The pharmacodynamic and pharmacokinetic profiles of nifedipine and nisoldipine were compared in a double blind, placebo-controlled study. Nisoldipine, 10 mg significantly reduced systolic blood pressure but nifedipine 20 mg retard did not, although both drugs had significant pharmacodynamic effects as evidenced by increased heart rates. The terminal elimination half-life in plasma was similar for both drugs with a mean of 2 h. The pharmacodynamics of nisoldipine were studied in 8 hypertensives following both acute and chronic administration. Antihypertensive efficacy was demonstrated after acute dosing and was maintained over 4 weeks of twice daily treatment as monotherapy.
