Influence of co-dergocrine mesilate/nifedipine compared to mefruside/nifedipine on circadian blood pressure in patients with essential hypertension.
Journal of human hypertension(1990)
摘要
This randomised, parallel group study was designed to compare the efficacy of nifedipine (40 mg once daily) combined with either the dopamine agonist, co-dergocrine mesilate (4 mg once daily) or the diuretic mefruside (25 mg once daily) in 40 patients with essential arterial hypertension and a diastolic blood pressure greater than 105 mmHg. Circadian blood pressure and heart rate were measured over 24 h every 15 min from 6 a.m. to 6 p.m. and every 30 min from 6 p.m. to 6 a.m. with an automatic, portable instrument (ICR 5300, Squibb) before and after a three-week treatment period. At the end of the three-week treatment period the mean value of all 24 h blood pressure measurements reflected highly significant decreases (2P less than 0.001), from 148/92 +/- 16/12 before treatment to 131/83 +/- 12/12 mmHg after treatment in the co-dergocrine mesilate/nifedipine group and from 145/92 +/- 16/10 before treatment to 129/84 +/- 10/6 mmHg after treatment in the mefruside/nifedipine group. Blood pressure reduction was still significant in both groups during the early morning hours at the end of the dosage interval. The efficacies of nifedipine combined with co-dergocrine mesilate or mefruside were comparable but side-effects were rated as more severe in the mefruside group. Therefore, the combination co-dergocrine mesilate/nifedipine may be preferable to the combination mefruside/nifedipine.
