PURPOSE To evaluate intestinal inflammatory and apoptotic processes after intestinal ischemia/reperfusion injury, modulated by pentoxifylline and hypertonic saline. METHODS It was allocated into four groups (n=6), 24 male Wistar rats (200 to 250 g) and submitted to intestinal ischemia for 40 min and reperfusion for 80 min: IR (did not receive any treatment); HS group (Hypertonic Saline, 4 ml/...

BACKGROUND Cardiopulmonary bypass may lead to many inflammatory responses that may cause myocardial dysfunction after open heart surgery. We aimed to investigate the effect of preoperative pentoxifylline treatment to reduce the occurrence of cardiopulmonary bypass-induced inflammatory response. METHODS In a prospective, randomized study, 40 patients undergoing coronary artery bypass graft sur...

It was hypothesized that pentoxifylline might improve the response to recombinant human erythropoietin (rh-Epo) in anemic renal failure patients. Sixteen patients with ESRD and rh-Epo-resistant anemia, defined by a hemoglobin of <10.7 g/dl for 6 mo before treatment and a rh-Epo dose of > or =12,000 IU/wk, were recruited. They were treated with oral pentoxifylline 400 mg o.d. for 4 mo. Ex vivo T...

Peripheral arterial disease (PAD) is a manifestation of atherosclerosis resulting in intermittent claudication (IC) or leg pain during physical activity. Two drugs (cilostazol and pentoxifylline) are approved for treatment of IC. Our previous work has reported no significant differences in gait biomechanics before and after drug interventions when PAD patients walked without pain. However, it i...

Objective: This study was designed to determine the effect of Pentoxifylline on the clinical and pathologic course of Oral Submucous Fibrosis (OSMF). Methods: This study was conducted as a randomized clinical trial incorporating a control group (antioxidant therapy, Tab Lycored once daily) in comparison to Pentoxifylline test cases (400mg 3 times daily, tablets). The treatment period was 3 mont...

We evaluated the effects of pentoxifylline and indomethacin and heparin in a rabbit model of disseminated intravascular coagulation (DIC) induced by infusion of 100 μg/kg/hour of Escherichia coli endotoxin lipoplysaccharide (LPS) for 6 hour. Heparin, indomethacin, pentoxifylline or saline were administered simultaneously with LPS. In addition, a control group was formed which was administered o...

The disposition of pentoxifylline and two of its active metabolites (metabolite 1 [M1] and metabolite 5 [M5]) were studied following i.v. (8 mg/kg) and p.o. (30 mg/kg) administration to eight normal dogs using a randomized crossover design. Blood samples were collected at fixed time intervals after drug administration for determination of drug concentrations, platelet aggregation, and plasma fi...

Type II reaction in leprosy, or erythema nodosum leprosum (ENL), is often characterized by severe clinical symptoms together with nerve function impairment leading to permanent disabilities. Thalidomide has been shown to be a highly effective drug for the treatment of ENL. It is, however, contraindicated for women of childbearing age due to its teratogenicity. On the other hand, pentoxifylline,...

The efficacy and safety of pentoxifylline were assessed in 297 adult patients with ischemic stroke in a multicenter, double-blind, randomized and placebo-controlled trial. Treatment was started within 12 hours after the stroke onset. Study medication was administered intravenously continuously (16 mg/kg/day, maximum 1,200 mg/day) for 3 days and per os (400 mg t.i.d.) for the remainder of 28 day...

OBJECTIVE We hypothesized that pentoxifylline, administered after phorbol myristate acetate (PMA), would diminish the severity of lung injury. SETTING Animal research laboratory. DESIGN Comparative study. SUBJECTS Mongrel dogs (n = 33). INTERVENTIONS Baseline measurements were obtained from the isolated blood-perfused dog lung lobes after 1 h of stable perfusion and ventilation. Four di...
