Brief summary
The purpose of this study is to determine the therapeutics effectiveness of oral pentoxifylline treatment in patients with IBS.
Detailed description
Disruption of the intestinal epithelial barrier is part of the pathophysiology of IBS favoring immune activation present in the mucosa of these patients and the development of symptoms in IBS. To evaluate the effect of treatment with pentoxifylline (PTX) in patients with IBS related to clinical response and modulation of the components of the epithelial barrier at the level of intestinal mucosa.
Interventions

Patients will take 800mg/day, via oral, of pentoxifylline. 400 mg of pentoxifylline each 12 hours (during meals time).Period: 3 months.
Patients will take 800mg/day, via oral, of pentoxifylline placebo. 400 mg of pentoxifylline placebo each 12 hours (during meals time).Period: 3 months.
