Comparative StudyPentoxifylline, a methyl xanthine derivative, reduces peritoneal adhesions and increases peritoneal fibrinolysis in rats.
Peritoneum has an intrinsic fibrinolytic activity that breaks the peritoneal adhesions. Peritoneal injuries with ischemia interfere this fibrinolytic activity and cause adhesions. Pentoxifylline, a methyl xanthine derivative, improves blood flow by decreasing its viscosity and also increases fibrinolytic activity in plasma. ⋯ PAI-1 levels were lower in animals receiving IP pentoxifylline compared to control animals and those treated with IV pentoxifylline (p = 0.048, p = 0.015, respectively). Peritoneal hydroxyproline levels were similar among the three groups. Our results suggest that pentoxifylline administration either through IV or IP may reduce peritoneal adhesion formation probably by altering peritoneal fibrinolytic activity.
