Trental belongs to the group of medications called vasoactive agents. This medication works by improving blood flow in the arms and legs. Pentoxifylline is used to treat chronic circulation disorders of the arms and legs, such as intermittent claudication (peripheral arterial disease) or ulcers due to poor blood supply.

Take Trental exactly as prescribed by your doctor. The usual recommended adult starting dose of pentoxifylline is 400 mg twice daily after meals. Your doctor may adjust the dose over time as needed to a maximum of 400 mg 3 times daily. Trental should be taken by mouth with a full glass of water with food. Taking this medicine with food may help decrease nausea and vomiting. Improvement in symptoms can occur in 2-4 weeks, but it may take up to 8 weeks to get the full benefit.
