    Abstract:
    In a controlled multicenter study 70 patients with chronic arterial occlusive disease stage IV according to Fontaine's classification were randomised to treatment with prostaglandin E1 (PGE1) or pentoxifylline (PX), administered over 4 weeks. Parameters of effectiveness were the reduction of analgesics, the relief of rest pain according to an analogue scale, the improvement of the ulceration according to an ulcer score and the healing of necrotic area. The results show that both forms of treatment produced a significant reduction in analgesic consumption and rest pain. Moreover in both groups a significant reduction of the ulcer score and healing of the necrotic area were observed. Side effects occurred in six patients of the PGE1-group and in ten patients of the PX-group, which required premature discontinuation of treatment in four patients of the PX-group. The study also demonstrated that PGE1 is more effective in the treatment of severe arterial occlusive disease than PX. With respect to the analgesic consumption, the reduction of ulcer score and the healing of necrotic area a significant difference was found in favour of PGE1. In accordance the six months follow-up examinations showed a marked deterioration in the PX-group opposed to the PGE1-group. The intravenous application of PGE1 over a period of 4 weeks in patients with severe arterial occlusive disease seems to be an effective therapeutical principle.
