Core Tip
Core Tip: Nor-ursodeoxycholic acid or norucholic acid is a short-chain shortened derivative of ursodeoxycholic acid. Pre-clinical animal studies have revealed conflicting results. Clinical data on primary cholestatic liver diseases and metabolic dysfunction-associated liver diseases are also limited. This narrative review comprehensively explores the mechanism of action and discusses the pharmacokinetics and pharmacodynamic differences with ursodeoxycholic acid. It also addresses the potential gap in the literature regarding the role of nor-ursodeoxycholic acid in metabolic dysfunction-associated liver diseases and primary sclerosing cholangitis based on primitive data.
