title: [Management of hypertension emergencies in elderly patients with isosorbide dinitrate aerosol].
abstract: In this clinical trial, we assessed the effectiveness and safety of isosorbide dinitrate spray administered through the oral mucosa in 20 elderly patients (> 60 years old) with a hypertensive emergency (mean arterial pressure > 140 mmHg and target-organ damage). The patents were given a first dose of 1.25 mg of spray when they were admitted; a second dose was administered 15 min. later if the mean arterial pressure had not decreased by > 15%. An electrocardiogram (ECG) was done on every patient immediately prior and 30 min. after administering the medication. Three patients (15%) had a good response with one dose while 17 patients (85%) required a second dose. Thirty patients had a significant reduction in arterial blood pressure (193 +/- 91,123 +/- 5.4 to 154 + 7.1/92.5 + 6.2 mmHg p < 0.005) as well as of the mean arterial pressure (146.8 +/- B to 113 +/- 5 mmHg 23%, p < 0.005 > in a period of 30 min. No adverse effects, rebound hypertension nor severe hypotension were observed. These figures remained under control for 3 h. Both ECG, were normal. A reduction of 13.5% heart rate was obtained (p < 0.005). Our observations suggest that isosorbide dinitrate aerosol is an effective and safe alternative for the treatment of elderly patients with hypertensive emergencies.
