Tauroursodeoxycholate Sodium is widely used in medical and pharmaceutical applications due to its protective and therapeutic properties. It is commonly employed in the treatment of liver diseases, such as primary biliary cholangitis and non-alcoholic fatty liver disease, as it helps reduce bile acid toxicity and inflammation. Additionally, it is utilized in ophthalmology to protect retinal cells and treat conditions like diabetic retinopathy and dry eye syndrome. Its ability to stabilize cell membranes and reduce oxidative stress makes it valuable in neuroprotective therapies, particularly for neurodegenerative diseases like Alzheimer’s and Parkinson’s. It is also studied for its potential in improving the efficacy of drug delivery systems by enhancing solubility and absorption of poorly soluble compounds.
