HR (Venoruton1000, Paroven, 0-[beta-hydroxyethyl]-rutosides) vs. Daflon 500 in chronic venous disease and microangiopathy: An independent prospective, controlled, randomized trial

Abstract

Objectives: The aim of this study was to demonstrate whether and how HR (Venoruton1000, Paroven, 0-[beta-hydroxyethyl]-rutosides) and Daflon (diosmin, 500 mg) were comparatively effective in improving the microcirculation in venous hypertension and microangiopathy. Methods: A group of 90 patients with severe venous hypertension due to chronic venous insufficiency, ankle swelling, and lipodermatosclerosis were included. After informed consent, patients were randomized into a Venoruton and a Daflon (DF) group: patients in the Venoruton group received oral HR (2 g/day for 8 weeks); those in the Daflon group received three 500-mg tablets daily every 8 hours. The two groups were comparable for age and sex distribution. The mean age was 41 years (SD ± 11) in the Venoruton group (46 patients) and 41.3 (SD ± 12) in the DF group (44 patients). Results: There were no differences in microcirculatory parameters between the Venoruton and DF treatment groups at inclusion. There was no significant change between inclusion and measurements at 8 weeks in the DF group. In comparison, a significant decrease (P
