Utilisation de l'acide ursod\u00e9soxycholique<\/strong><\/h2>\n

1. Une \u00e9tude montre que l'acide ursod\u00e9soxycholique peut \u00eatre utilis\u00e9 pour pr\u00e9venir les infections \u00e0 n\u00e9ocoronavirus. Il r\u00e9duit le nombre de r\u00e9cepteurs cellulaires de l'enzyme de conversion de l'angiotensine sur les cellules, ce qui rend plus difficile la p\u00e9n\u00e9tration des virus dans les cellules humaines.<\/p>\n

2. L'acide ursod\u00e9soxycholique a un effet cholestatique b\u00e9n\u00e9fique car il augmente la s\u00e9cr\u00e9tion d'acides biliaires lorsqu'il p\u00e9n\u00e8tre dans l'organisme du patient.<\/p>\n

3. Il inhibe \u00e9galement la synth\u00e8se du cholest\u00e9rol dans le foie, r\u00e9duisant ainsi le cholest\u00e9rol et les esters de cholest\u00e9rol contenus dans la bile. En outre, des \u00e9tudes ont montr\u00e9 que l'acide ursod\u00e9soxycholique peut avoir un effet immunomodulateur dans le cas de maladies h\u00e9patiques chroniques.<\/p>\n

4. L'acide ursod\u00e9soxycholique est utile pour la r\u00e9duction du cholest\u00e9rol et la dissolution des calculs, et peut \u00eatre utilis\u00e9 pour le traitement de petits calculs dans la v\u00e9sicule biliaire sans intervention chirurgicale.<\/p>\n
