A preliminary clinical study on an antihypertensive agent, troxonium tosylate

The effects of a new antihypertensive agent, troxonium tosylate, were studied in a group of 22 patients whose ages ranged from 48 to 88 years. Fourteen of these were classified as hypertensive because of a diastolic pressure over 95 mm. Hg. Eight were normotensive. This was a double-blind study. A dose of 600 mg. daily produced a significant fall in systolic and diastolic pressure relative to control levels in the hypertensives, while in the normotensives a dose of 600 mg. produced no significant effect. A dosage of 1000 mg. daily produced a significant fall in diastolic pressure from control levels in both these groups.Blood counts, urinalyses, blood urea nitrogen and cholesterol levels remained unchanged throughout the study, and no side effects were experienced by the patients.
