[Antihypertensive effect and adverse effects of isradipine in patients with sever hypertension. Results of an open multicenter study].
Antihypertensive Efficacy and Tolerability of Isradipine in Patients with Severe Hypertension/Results of an open multicenter study. In this open multicentre study 55 patients (mean age 51.2 years) with severe hypertension (diastolic blood pressure > 115 mmHg) were treated for seven weeks with the calcium antagonist of the dihydropyridine type isradipine (CAS 75695-93-1, Lomir). If necessary, metoprolol or enalapril were added to the regimen. Before inclusion into the active treatment phase, responsiveness of the patients to a single administration of isradipine (5 mg) was compared with placebo. Preexisting antihypertensive therapy (18 patients) was to be maintained during the study period. Blood pressure was recorded with an automatic device. During the 7-week period blood pressure decreased from 173.7/124.8 mmHg to 143.2/97.8 mmHg. Both the group with isradipine monotherapy (n = 32) and the combination group (n = 11) showed a significant reduction in systolic and diastolic blood pressure. Diastolic blood pressure response, defined as a decline of more than 15 mmHg, was noted in 87.5% (monotherapy) and 72.7% (combination group) of patients. On the whole, blood pressure was normalized in 27.9% of the participants. Nineteen patients experienced 43 adverse events, most of which were rated mild to moderate. Therapy was withdrawn in only one patient (due to ankle edema). The most frequent adverse event was headache (20.9%).
