Micronised purified flavonoid fraction (MPFF) [Daflon 500 mg], an oral phlebotropic drug consisting of 90% micronised diosmin and 10% flavonoids expressed as hesperidin, improves venous tone and lymphatic drainage, and reduces capillary hyperpermeability by protecting the microcirculation from inflammatory processes. The absorption of diosmin is improved by its micronisation to particles with a diameter<2 microm. Compared with placebo, MPFF 500 mg twice daily significantly decreased ankle or calf circumference, and improved many symptoms of chronic venous insufficiency (CVI) and plethysmographic parameters in two randomised, double-blind, 2-month studies. Improvement in symptoms was parallelled by an improvement in health-related quality of life in a nonblind, 6-month trial. Significantly more venous leg ulcers
