    Abstract:
    Hypertensive urgencies are clinical settings in which a steady therapeutic intervention is needed, but this may be safely stretched over some hours. An appropriate antihypertensive drug to use in an urgency should show a potent but gradual effect: it should reduce BP in a short time and it should be easy to modulate the antihypertensive effect, according to individual needs. Sublingual administration is the easiest way for a therapeutical intervention in an urgency. The use of nicardipine administered sublingually was tested in comparison with nifedipine, during a hypertensive urgency, in 24 hypertensive subjects. The peak effect of nifedipine occurred within 10-20 minutes after the administration, whereas that of nicardipine occurred after 45-50 minutes; nevertheless a significant decrease both in systolic and diastolic blood pressure was already observed 20 min after nicardipine administration. The hypotensive effect of nicardipine was longer lasting than that of nifedipine. Some adverse effects were observed in the group receiving nifedipine, whereas no side effects were described by patients receiving nicardipine.
