Full Prescribing Info
Antiplatelet/Hemorrheologic agent.
Pentoxifylline improves the flow property of blood. It is known to enhance tissue oxygenation. It produces dose-related decrease in blood viscosity. It also inhibits neutrophil adhesion and activation.
Pharmacokinetics: Pentoxifylline is readily absorbed through the gastrointestinal route but undergoes first-pass hepatic metabolism. Some metabolites are active. The apparent plasma t½ of pentoxifylline is reported to be 0.4-0.8 hr; that of the metabolites varies from 1-1.6 hrs. In 24 hrs, most of the dose is excreted in the urine mainly as metabolites and <4½ is recovered as unchanged drug in the feces. Elimination of pentoxifylline is decreased in elderly patients and patients with hepatic disease.
As a vasodilator in the treatment of peripheral and vascular disorders.
