    Abstract:
    The serotonergic antagonist ketanserin (K) was compared to nifedipine (N) in a five-center international study on hypertensive patients over the age of 50 years. After a 4-week placebo run-in period, patients were randomly assigned to receive for 3 months either ketanserin (40 mg b.i.d. after 2 weeks of 20 mg b.i.d.) or nifedipine (20 mg N retard b.i.d.). After 1 month, monotherapy patients whose blood pressure was not sufficiently reduced received a diuretic in combination therapy. At the end of the active treatment period, patients who had remained on monotherapy received placebo until hypertension returned or for a maximum of 2 months. One hundred and seventeen patients were entered in the study, 58 on K and 59 on N. More patients switched to combination with a diuretic in the K group (14 patients) than in the N group (6 patients). The overall reduction in blood pressure was similar for K and N. Total response rate was high (96%) for the two drugs. Blood pressure was reduced both at peak and trough drug levels. No orthostatic reactions were observed, and no rebound hypertension occurred at discontinuation of therapy. Ketanserin monotherapy slightly decreased heart rate (-1 beats/min). whereas N produced a significant increase (+6 beats/min). Body weight significantly increased with K (+1.1 kg) and was unchanged with N. More patients complained of adverse reactions during N monotherapy (47%) than during K monotherapy (34%). Flushing and leg edema were more frequent with N.
