Oxerutins (Venoruton®): Efficacy in Chronic Venous Insufficiency A Double-Blind, Randomized, Controlled Study

The aim of this study was to confirm the clinical efficacy of oxerutins by evaluation of venous parietal tone and microvascular perfusion in a double-blind, randomized, placebo-controlled study. The study included 60 patients. Venous tone was evaluated by air-plethysmography (APG) in patients with venous insufficiency (CVI). Forty patients were treated with oxerutins and 20 with placebo for 4 weeks. The dose of the first 2 weeks was higher than that of the following 2 weeks. The age range was between 18 and 65 years. Randomized patients received treatment (oxerutins or placebo) according to the grade of CVI. Patients with grade I CVI received 2 g/day in the first 2 weeks of treatment and 1 g/day in the following weeks. Patients with grade II CVI received 3 g/day in the first 2 weeks and 2 g/day in the following 2 weeks. Visits were scheduled at baseline time (visit 1), at 2 weeks (visit 2) and at 4 weeks (visit 3). They were assessed with the following: (1) APG; (2) light reflection rheography (LRR); (3) ...
