Drug intelligence / Profile preview
AD-2341 is a pharmaceutical candidate developed by **Addpharma** (a subsidiary of **Yuhan Corporation**) for the treatment of **gastritis**. It is a specific formulation of **artemisia asiatica extract**, a botanical drug derived from the *Artemisia asiatica* plant. The extract contains active flavonoids such as eupatilin and jaceosidin, which provide gastroprotective effects by stimulating the synthesis of endogenous **prostaglandins**, increasing gastric mucus secretion, and scavenging free radicals. AD-2341 has been primarily studied as a component of **AD-234**, a fixed-dose combination (FDC) therapy that pairs artemisia asiatica extract with the cytoprotective agent **rebamipide**. This combination aims to provide synergistic protection of the gastric mucosa and improve symptoms in patients with acute or chronic gastritis.
