I would not expect many doctors know about pentoxifylline's potential, as it is thought to be an older drug to improve circulation and has fallen out of favor with current Plavix in the mix.

Wow Mrs D you have really taken me back a bit,I studied this drug 25yrs ago during my university days, I worked in a cancer research lab and we were looking at Pentoxyfilline as an anti metastatic agent- it didn't decrease the tumours as we were hoping but stimulated their growth instead. Thanks for the trip down memory lane
