Open studies with prazosin in the treatment of essential hypertension. Prazosin Research Group in Japan.
The clinical usefulness of prazosin was investigated in 67 patients with mild to moderate essential hypertension for 6 to 12 weeks. The daily doses were increased from 3 to 9 mg according to the responses of the patients. The average reduction of mean arterial blood pressure by 6 weeks' prazosin treatment was 13-4 +/- 1-7 mm Hg. Thirty-three patients (49-3%) showed good or excellent responses to prazosin. Serious side effects or laboratory abnormalities did not appear in this trial, through postural dizziness was found in 6-0%. Prazosin seems to be a useful antihypertensive agent in the treatment of patients with mild or moderate essential hypertension.
