In an open clinical trial 14 patients with intermittent claudication caused by an obliteration of the femoral artery received 400 mg pentoxifylline 3 times daily over a period of 6 months. The walking distance, time to peak flow and calf ergometry showed a significant increase. Minor improvement of working hyperemia and peak flow could be found. The systolic pressure gradient over the obstruction didn't change. No patient complained about side effects.
