    Abstract:
    The antihypertensive effect of twice-daily nicardipine, an investigational calcium-channel blocker, was evaluated in a placebo-controlled, single-blind trial in 18 adult patients with essential hypertension (supine diastolic blood pressure [BP] of greater than or equal to 95 and less than or equal to 120 mmHg). Following a 4-week run-in period in which patients received placebo for the final 2 weeks, nicardipine was administered for 12 weeks with a treatment goal of a supine diastolic BP of less than 90 mmHg at 12 hours postdosing or to a maximum dose of 60 mg twice daily. Supine and standing BPs and heart rates were determined at 1 hour and 12 hours postdosing. At all dose levels, supine and standing BPs were reduced at 1 hour after dosing, with partial loss of efficacy seen at 12 hours. Increases in heart rate seen at 1 hour were not significant at 12 hours. Eight patients withdrew from the study for minor, although troublesome, side effects, such as palpitations and headaches. These data suggest that nicardipine monotherapy given in a twice-daily dosing regimen has only a limited role to play in the chronic treatment of patients with essential hypertension.
