Linaprazan is an experimental drug for the treatment of gastroesophageal reflux disease (GERD). Unlike the proton-pump inhibitors (PPIs) which are typically used to treat GERD, linaprazan is a potassium-competitive acid blocker (P-CAB).[1][2] Linaprazan was developed by AstraZeneca, but it was not successful in clinical trials.[3]

The drug was then licensed to Cinclus Pharma,[4] which is now investigating linaprazan glurate, a prodrug of linaprazan which is expected to have a longer biological half-life than linaprazan itself.[4]
