TL;DR: Recommendations that most patients with malignant hypertension can be managed without recourse to parenteral therapy are supported.
Abstract: We have compared the efficacy and safety of slow release nifedipine and atenolol given orally as initial treatment for malignant hypertension. Twenty consecutive black patients with untreated malignant hypertension, whose diastolic pressure remained greater than 120 mm Hg after 3 h bed rest, were randomized to receive either slow release nifedipine 40 mg at 1 and 12 h, or atenolol 100 mg at 0 h only. Patients remained supine throughout the study. Blood pressure was measured using a semi-automatic recorder (Omega 1000) at 15 min intervals from -3 to 24 h. Baseline blood pressure was similar in the nifedipine (233/142 mm Hg) and atenolol (226/141 mm Hg) groups. The rate of fall of pressure was greater after nifedipine whose maximum hypotensive effect occurred 4-5 h after each dose. Blood pressure decreased more slowly and more enduringly after atenolol, although the extent of fall was the same (delta BP 5 h after first dose nifedipine = 67/41 mm Hg; delta BP 16 h after atenolol = 64/40 mm Hg). There were no precipitous falls in pressure. No patient developed focal neurological signs, nor was heart failure precipitated by either form of treatment. These results support recommendations that most patients with malignant hypertension can be managed without recourse to parenteral therapy.
