  Pentoxifylline (PTX), a methil-xantine that inhibits phosphodiesterase IV, has long been used in the treatment of obliterant peripheral arteriopathy and circulatory alterations related with arteriosclerosis, diabetes or inflammation [1,2]. This low cost drug present minimal side effects and low toxicity usually reported in chronic use and it have an interesting immunomodulatory, bronchodilatory, anti-inflammatory and antiviral properties. The principal mechanism of these properties is the reduction of TNF-ɑ, IL-1, IL-6 and IL-8 [3]. These properties are confirmed in vitro but efficacy of PTX in vivo is controversial; for some authors, the weak anti-inflammatory and immunomodulatory action in vivo is due to the low serum concentrations of the drug at usual doses and they propose the use of high dose ou continuous vein perfusion of PTX to increase efficacity in vivo.
