Effects of buflomedil in a group of patients with chronic peripheral arterial diseases. Clinical and hemorheological evaluation

Abstract

Fifty-three patients suffering from chronic arterial diseases of the lower limbs were treated with buflomedil, a vasoactive drug with vasodilating and hemorheological action on the microcirculation. The patients suffered from pain on walking or pain at rest; they were given 300 mg buflomedil orally twice a day for a period of about 2 months. The walking distance before pain onset was checked in all patients before and after the trial. Blood and plasma viscosity, haematocrit and fibrinogen and a Doppler velocimetry were also recorded. A significant improvement of the walking distance before pain onset was observed in nearly all patients, and in most patients the morphology of the velocity waves improved, too. No clear correlation between the positive clinical results and the hemorheological parameters studied could be observed.
