Trental (Pentoxifylline) - Summary



TRENTAL® (pentoxifylline) tablets for oral administration contain 400 mg of the active drug in a controlled-release formulation.

TRENTAL is indicated for the treatment of patients with intermittent claudication on the basis of chronic occlusive arterial disease of the limbs. TRENTAL can improve function and symptoms but is not intended to replace more definitive therapy, such as surgical bypass, or removal of arterial obstructions when treating peripheral vascular disease.

Published Studies Related to Trental (Pentoxifylline)

Pentoxifylline for intermittent claudication. [2012]
CONCLUSIONS: Given the generally poor quality of the published studies

Pentoxifylline improves nonalcoholic steatohepatitis: a randomized placebo-controlled trial. [2011.11]
CONCLUSION: PTX improved histological features of NASH compared to placebo. PTX was well tolerated in patients with NASH. Copyright (c) 2011 American Association for the Study of Liver Diseases.

Pentoxifylline decreases serum levels of tumor necrosis factor alpha, interleukin 6 and C-reactive protein in hemodialysis patients: results of a randomized double-blind, controlled clinical trial. [2011.10.03]
CONCLUSIONS: Pentoxifylline significantly decreased serum concentrations of TNF-alpha, IL-6 and CRP compared to placebo. Pentoxifylline could be a promising and useful strategy to reduce the systemic inflammation frequently observed in patients on HD.

Pentoxifylline (anti-tumor necrosis factor drug): effective adjuvant therapy in the control of ocular cicatricial pemphigoid. [2011.09]
PURPOSE: The detection of tumor necrosis factor-a (TNF-a) in conjunctiva affected by ocular cicatricial pemphigoid (OCP) may indicate that this cytokine plays an important role in its pathogenesis. The purpose of this randomized, controlled, comparative, blinded study was to evaluate the effectiveness of adding pentoxifylline as an anti-TNF-a drug to the well-documented therapy of steroids and cyclophosphamide in controlling OCP... CONCLUSIONS: The significantly increased level of serum TNF-a in OCP as compared to controls proves that TNF-a has an important role in the pathogenesis of this disease. The study illustrates that the addition of pentoxifylline to pulse steroid cyclophosphamide therapy is an effective, safe, and economical method in controlling OCP through directly reducing TNF-a levels, with long periods of remission as detected in our 18-month follow-up period.

Pentoxifylline for renoprotection in diabetic nephropathy: the PREDIAN study. Rationale and basal results. [2011.09]
STATEMENTS OF THE PROBLEM: Diabetic nephropathy (DN) is the main cause of end-stage renal disease (ESRD). Renin-angiotensin system (RAS) blockade is the standard of care; however, a significant proportion of patients progress to ESRD. Pentoxifylline (PTF) possesses properties suggesting potential renoprotective efficacy. The aim of the Pentoxifylline for Renoprotection in Diabetic Nephropathy (PREDIAN) study is to test the efficacy of PTF addition to RAS blockade on the progression of DN. Here we report the study design and the baseline patient characteristics... CONCLUSIONS: The PREDIAN study will provide evidence on the renoprotective benefit of PTF in addition to interventions of proven efficacy (RAS blockade) in DN. Copyright (c) 2011 Elsevier Inc.

Clinical Trials Related to Trental (Pentoxifylline)

Pentoxifylline/Nonalcoholic Steatohepatitis (NASH) Study: The Effect of Pentoxifylline on NASH [Recruiting]

Prevention of Capsular Contracture Using Trental and Vitamin E [Recruiting]
The main purpose of this research study is to determine if the use of Trental and Vitamin E compared to Placebo (an inactive substance) will decrease the incidence and severity of contractures (shrinking and or hardening of tissue surrounding the implant) associated with breast implant reconstruction following radiation treatment. Another goal is to find out the impact that Trental and Vitamin E compared to Placebo may have on implant loss or need for surgical intervention in the setting of chest wall radiation after reconstruction. In addition, the investigators want to evaluate the patient's sense of well being and quality of life.

Renal Effect of Pentoxyphylline in High Risk Patients Undergoing Angiography [Not yet recruiting]
The investigators will study 2 separate groups:

- Cardiology patients undergoing invasive coronary angiography +/- PCI (Percutaneous

coronary intervention).

- Patients undergoing CT examination with contrast medium. All patients will receive

intravenous (I. V) hydration for 8-12h before and 36 to 48 h after angiography with 0. 45% saline 100ml/h.

All patients will receive oral N-acetyl cysteine 1200 mg twice daily, a day before, on the day of the angiography and for another 48 hours.

In addition, patients will be assigned to receive oral pentoxyphylline (P group) or placebo

(C - control group) tablets 3 times a day one day before, on the day of the procedure and

for another 48 hours.

Baseline Serum Creatinine (S. Cr) levels in will be taken before angiography and two days after angiography. Radio-contrast nephropathy is defined, in this study, as increase in serum ≥ 25 % of baseline after injection of the radio-contrast agent. Pentoxyfylline is an orally active haemorheological agent for the treatment of peripheral vascular disease, cerebrovascular disease and a number of other conditions involving a defective regional microcirculation. Pentoxyfylline acts primarily by increasing red blood cell deformability, by reducing blood viscosity and by decreasing the potential for platelet aggregation and thrombus formation (mechanism unclear). Pentoxyfylline has also proven to have a significant anti inflammatory effect as well as anti oxidant effect, mechanisms considered to be important patho-physiological causes of contrast induced nephropathy.

Pentoxifylline (Trental) as a Modulator of Tumor Necrosis Factor and of HIV Replication in Patients With AIDS [Completed]
To determine whether pentoxifylline lowers tumor necrosis factor (TNF) levels in AIDS patients. Pentoxifylline decreases tumor necrosis factor (TNF), and therefore should decrease such TNF-intensified events as cachexia, enhanced HIV expression, and inhibition of zidovudine (AZT) activity.
