This invention provides the use of terazosin or its pharmaceutically acceptable salts in the preparation of medicaments for the prevention and / or treatment of
liver fibrosis, relating to the field of
biomedical technology. This invention is the first to discover that terazosin or its pharmaceutically acceptable salts can be used to prevent and treat
liver fibrosis. It reveals that terazosin or its pharmaceutically acceptable salts can improve the degree of
liver fibrosis by improving
liver function, reducing the content of α-SMA (a marker of activated hepatic stellate cells) in
liver tissue, reducing the content of Col1a1 in
liver tissue, and reducing collagen deposition in
liver tissue. Furthermore, the liver-targeted sustained-release
drug provided by this invention can reduce the
peak plasma concentration of terazosin and prolong its
plasma half-life, achieving therapeutic effects equivalent to multiple low-
dose injections of terazosin, and has broad application prospects.
