title: Efficacy of a 6-month treatment with Daflon 500 mg in patients with venous leg ulcers associated with chronic venous insufficiency.
abstract: OBJECTIVE
  Epidemiological data show that standard compression therapy for leg ulceration in chronic venous insufficiency (CVI) often fails to effectively improve patients' condition. This study assesses the contribution of Daflon 500 mg added to conventional therapy in the healing of hypostatic ulcers of CVI patients.
  
  
  METHODS
  Patients of about 65 years were included, with ulcers > or = 2 and > or = 10 cm diameter on 1 or 2 limbs, Doppler ankle/arm pressure index > 0.9, and no recent history of skin graft. Controls (n=68) remained on compression alone while the tested group (n=82) also received Daflon 500 mg 2 tablets/day during 6 months. Treatment could be stopped as soon as the reference ulcer appeared fully healed. Primary endpoints were the rate of healed ulcers and the time to complete healing assessed by planimetry/photography and clinical examination. Variations of the ulcer surface, appearance of the skin, and clinical symptoms of CVI were the secondary criteria.
  
  
  RESULTS
  Only 7% of Daflon 500 mg patients necessitated the full 6 month therapy. Whatever the lesion size, from W8 significantly more healed ulcers were observed under Daflon 500 mg (p=0.004), and the ulcer surface was more reduced (p=0.012). For large ulcers, the rate of healing was approximately 2-fold higher with Daflon 500 mg, and the percentage of ulcers healed before W24 was significantly higher (p=0.008). Heavy leg sensation was significantly improved by Daflon 500 mg from W4 (p < 0.05). No treatment-related side effects were reported and the acceptability was considered excellent by 85% of Daflon 500 mg patients.
  
  
  CONCLUSIONS
  Six months of Daflon 500 mg in addition to compression significantly improve some clinical symptoms and accelerate the healing process in patients with ulcerous complications of CVI, with a good acceptability.
