Nicardipine as antihypertensive monotherapy: positive effects on quality of life

The effects of nicardipine and propranolol on patients' quality of life were compared during a double-blind, multicentre, parallel, randomised study of hypertension therapy. After a placebo run-in period, the doses for each patient were successfully titrated to reduce supine diastolic blood pressure to less than 90 mmHg with either nicardipine 60 or 90 mg/day (123 patients) or with propranolol 90-240 mg/day (120 patients). Both drugs demonstrated similar efficacy in reducing systolic and diastolic blood pressure. Total duration of therapy ranged from 6-12 weeks. The Nottingham Health Profile questionnaire was used to assess the effect of each treatment on the patients' quality of life. The overall quality of life score for patients on nicardipine showed a tendency toward improvement, while for those on propranolol, the trend was toward overall worsening. The differences between the two treatment groups were statistically significant for males (P = 0.02). The analysis of the separate components of this evaluation demonstrated that physical mobility was reported to be decreased more for the propranolol-treated patients than for the nicardipine-treated patients (P = 0.02). In contrast to the propranolol-treated patients, the nicardipine-treated patients reported improvements for sleep, social life, work, sex life, and for activities related to hobbies and interests. A second questionnaire was used to assess the effects of the therapies on work productivity. Among those patients who worked for pay, more patients treated with propranolol than those treated with nicardipine rated themselves as less productive at work (P = 0.02).(ABSTRACT TRUNCATED AT 250 WORDS)
