Tenatoprazole is a proton pump inhibitor drug candidate that was undergoing clinical testing as a potential treatment for reflux oesophagitis and peptic ulcer as far back as 2003.[1] The compound was invented by Mitsubishi Tanabe Pharma and was licensed to Negma Laboratories (part of Wockhardt as of 2007[2]).[3]:22

Mitsubishi reported that tenatoprazole was still in Phase I clinical trials in 2007[4]:27 and again in 2012.[3]:17

Tenatoprazole has an imidazopyridine ring in place of the benzimidazole moiety found in other proton pump inhibitors, and has a half-life about seven times longer than other PPIs.[5]
