Pentoxifylline is a 400 mg extended release tablet and the generic equivalent of Trental. It is being marketed by Hoechst Marion Roussel. Pentoxifylline extended release tablets are indicated for the treatment of leg pain caused chronic occlusive arterial disease of the limbs. Patient walking distance and daily activities are limited by the disease. Both Faulding and Mylan are now manufacturing Pentoxifylline.

In a comparison between aspirin and pentoxifylline in the elderly, the level of pain did not change significantly with either aspirin or pentoxifylline, but patient’s walking distance was extended with the pentoxifylline group.

Pentoxifylline increases red blood cell flexibility and improves blood flow.
