For many patients with lower limb ischemia, surgical treatment is not beneficial. We have studied the efficacy of combination therapy with sildenafil (Viagra) by Pfizer, France, and cerebrolysin (Ever Neuro Pharma, Austria) for lower limb ischemia in the Wistar rat model. The animals were divided into 6 groups (20 rats each): intact animals; sham-operated animals; rats with ischemia and no treatment administered (controls); rats with ischemia who received a 28-day monotherapy with sildenafil (2.2 mg/kg orally); rats with ischemia who received a 28-day monotherapy with 0.005 ml cerebrolysin; rats with ischemia who received a combination therapy with 2.2. mg/kg sildenafil for 7 days and 0.005 ml i. m. cerebrolysin for 10 days. Microcirculation in shin muscles was evaluated on days 21 and 28 of the experiment. On the same days, rats were overdosed with anesthetics and sacrificed in tens. Then, histological sections of shin muscles were prepared. Regional blood flow was significantly higher (p <0.05) in three experimental groups, compared to the controls; however, the combination therapy was far more effective than monotherapy, regardless of the medication used. Macroscopically, the muscles of the animals included into the experimental groups did not differ from the muscles of the intact animals; microscopically, no necrotic lesions were observed in the experimental groups that were typical for the ischemized rats who had received no treatment. Neovascularization was also observed in the experimental groups.
