Jaguar’s name is now Jaguar Health!

On Monday, July 31, the merger of Jaguar Animal Health and Napo Pharmaceuticals became effective. Napo focuses on the development and commercialization of proprietary gastrointestinal pharmaceuticals for the global human marketplace from sustainably derived plants used traditionally in rainforest areas. As a result of the merger, Jaguar’s name is now Jaguar Health, Inc., and Napo is a wholly-owned subsidiary of Jaguar, focused on the continuing commercialization of its Mytesi® (crofelemer) product, which is approved by the U.S. FDA for the symptomatic relief of noninfectious diarrhea in adults with HIV/AIDS on antiretroviral therapy.
