Introduction • The liver is one of the most important organs of the body. It performs a fundamental role in the regulation of diverse physiological processes, and its activity is related to different vital functions, such as metabolism, secretion, and storage. • Cirrhosisis a diffuse disorganization of normal hepatic structure by extensive fibrosis associated with regenerative nodules. Advanced cirrhosis leads to major alterations in the hepatic vascular bed and is usually irreversible • Fibrosisconsists of the accumulation of extracellular matrix (ECM) proteins, mainly fibrillar collagen, as the result of both increased ECM synthesis and decreased degradation of matrix.
Interventions in Cirrhosis management • There is no standard treatment for liver fibrosis, there are several therapeutic approaches to control liver fibrosis. • The ideal antifibrotic therapy would be one that is liver-specific, well tolerated when administered for prolonged periods of time, and effective in attenuating excessive collagen deposition without affecting normal ECM synthesis • Antioxidantsare the most promising drugs in treatment or prevention of liver fibrosis. They inhibit HSC activation, protect hepatocytes.
