Overview of Polidocanol as a Pharmaceutical Agent
Polidocanol, also known as lauromacrogol 400, is a local anesthetic and sclerosant used primarily in the treatment of varicose veins, spider veins, and hemorrhoids. Its capacity to induce endothelial damage leading to vessel sclerosis makes it valuable in minimally invasive vascular therapies. Its mechanism involves disrupting the endothelium lining, promoting fibrosis and vessel obliteration.
Given its medical utility, the supply chain for polidocanol involves carefully regulated manufacturers adhering to stringent quality standards. Many suppliers operate globally, ensuring availability for healthcare providers, pharmaceutical companies, and specialty clinics.
