Sucampo Pharmaceuticals, Inc. is a global biopharmaceutical company focused on research, discovery, development and commercialization of drugs based on ion channel activators known as prostones. The Company�s prostone-based compounds target the ClC-2 and big potassium (BK), ion channels. It is focused on developing prostones to treat gastrointestinal, ophthalmic, neurologic, and oncology-based inflammatory disorders, and is also considering other therapeutic applications of its drug technology. The Company�s products include AMITIZA (lubiprostone) and RESCULA (unoprostone isopropyl). AMITIZA is marketed in the United States for three gastrointestinal indications: chronic idiopathic constipation (CIC), in adults, irritable bowel syndrome with constipation (IBS-C), in adult women, and opioid-induced constipation (OIC), in adult patients with chronic, non-cancer pain. RESCULA is a BK channel activator and has a different mechanism of action than other IOP lowering agents on the market.
