title: The treatment of mild to moderate essential hypertension with tienilic acid (ticrynafen).
abstract: This paper reports a clinical trial of tienilic acid, a new diuretic with uricosuric properties, in 23 patients with mild to moderate hypertension (standing diastolic blood pressure 90-120 mmHg). Tienilic acid was compared with hydrochlorothiazide in a variable-dose, double-blind cross-over study, and the duration of therapy was 8 weeks for each drug. The falls in blood pressure (systolic/diastolic) were: 11/11 mmHg supine and 17/11 mmHg standing for tienilic acid, and 8/12 mmHg supine and 9/17 mmHg standing for hydrochlorothiazide. There were no significant differences between the two drugs in their effect on blood pressure and heart rate, and regarding side-effects and laboratory results, except for serum uric levels (mean fall of 1,5 mg/dl with tienilic acid and mean increase of 1.1 mg/l with ydrochlorothiazide).
