Pentoxifylline for Vascular Calcification in Kidney Disease

This study is research to find out if the drug pentoxifylline can help prevent or lessen the problem of blood vessel hardening (vascular calcification) in people with chronic kidney disease (CKD). People with CKD are at higher risk for heart problems and blood vessel hardening. Vascular calcification happens when calcium builds up in the blood vessels, making them stiff. Pentoxifylline is a drug that might have helpful effects that could reduce this hardening. In this study, some CKD patients will receive pentoxifylline in addition to their usual medications, while others will only receive their usual medications. The researchers will then compare the amount of vascular calcification in both groups over 6 months to see if pentoxifylline makes a difference. The goal is to learn if pentoxifylline could be a new way to protect the blood vessels of people with chronic kidney disease.
