Sulodexide promotes arterial relaxation via endothelium-dependent nitric oxide-mediated pathway.
2019
Biochemical pharmacology
Raffetto JD, Calanni F, Mattana P, Khalil RA
Plain English This study looked at how sulodexide (SDX), a medication used to treat blood vessel disorders, affects the ability of arteries to relax. The researchers found that when they treated isolated rat arteries with SDX, it significantly reduced contractions caused by a chemical called phenylephrine and promoted relaxation, especially through the production of nitric oxide (NO). Specifically, SDX could induce relaxation in various concentrations, and disruptions to the endothelium (the inner lining of blood vessels) or blocking nitric oxide production dramatically reduced its effectiveness.
Who this helps: This benefits patients with vascular issues, as SDX may improve blood flow and reduce complications from artery constriction.
