The aim of this study was the evaluation of the treatment of venous ulcers with pentoxifylline (PXF) in 12 months. This double-blind, placebo-controlled trial was conducted in GCP. Patients were included after consent and randomized for PXF (400 mg three times daily) or placebo. The number of healed ulcers, the variation in the area of ulceration, and the variation in microcirculatory parameters (laser-Doppler flux and skin PO2) were considered as endpoints. Of the 85 patients included, 80 completed the study (41 in the PXF and 39 in the placebo group). The groups were comparable. Healing occurred in 88% of limbs in the PXF and in 44% in the placebo group (44% difference; p<0.02). The average area reduction was 93% in the PXF and 56% in the placebo group. Microcirculation was significantly improved in both groups at 12 months. The decrease in flux and the increase in PO2 were greater in the PXF group (p<0.05). Considering the proportion of healed ulcers a better outcome was observed with PXF (p<0.02; 12% of nonhealed ulcers in the PXF vs 56% in the placebo group). The ulcerated area decreased 93% in the PXF vs 56% in the placebo group (40% difference; p<0.02). Tolerability was comparable (6% in the PXF group and 5% in the placebo group complained for treatment). No important side effects were observed. In conclusion, treatment with PXF in venous ulcers improves healing and microcirculation and should be considered in slow-healing venous ulcers.
