Pentoxifylline: How a 'Blood-Flow' Drug Helps Diabetic Foot Ulcers

In this episode of Diabetic Foot Files Dr. G explores pentoxifylline — a decades-old methylxanthine drug — and how it improves microcirculation, reduces blood viscosity and inflammation, and may support healing in diabetic foot ulcers, venous leg ulcers, and intermittent claudication.

The episode reviews the drug’s history, mechanisms of action, clinical uses, dosing considerations, side effects, and how pentoxifylline fits into modern multimodal limb salvage and wound care strategies.
