Trental (Pentoxifylline) is a medication commonly used to improve blood flow. It works by making red blood cells more flexible, helping them to flow more easily through the blood vessels, and by decreasing the viscosity (thickness) of the blood. This can be particularly beneficial in conditions like peripheral artery disease, where blood flow to the limbs is restricted.The typical dose for Pentoxifylline (Trental) is 400 mg taken three times daily, but the specific dosage may vary depending on the individual’s medical condition and doctor’s instructions.
