Tenatoprazole, also known as TU-199 and STU-Na, is a proton pump inhibitor drug candidate that was undergoing clinical testing. The compound was invented by Mitsubishi Tanabe Pharma and was licensed to Negma Laboratories (part of Wockhardt as of 2007). Mitsubishi reported that tenatoprazole was still in Phase I clinical trials in 2007 and again in 2012. STU-Na will be used for treatment of acid related diseases (gastroduodenal ulcers, erosive or ulcerative esophagitis due to gastroesophageal reflux disease). Tenatoprazole has an imidazopyridine ring in place of the benzimidazole moiety found in other proton pump inhibitors; the binding sites of tenatoprazole were in the TM5/6 region at Cys813 and Cys822 as shown by tryptic and thermolysin digestion of the ATPase labeled by tenatoprazole. It has a half-life about seven times longer than other PPIs.

Sennosides are hydroxyanthracene glycosides derived from Senna leaves. They have been used as natural, safe time-tested laxatives in traditional as well as modern systems of medicine. Sennosides (Senna) is a medication used to treat constipation and empty the large intestine before surgery. The medication is taken by mouth or via the rectum. It typically begins working in minutes when given by rectum and within twelve hours when given by mouth. It is a weaker laxative than bisacodyl or castor oil. Senna is an FDA-approved nonprescription drug for adults and children ages 2 years and older. It is also used for bowel preparation before colonoscopy and diagnostic imaging.

Vonoprazan (Vonoprazan fumarate or TAK-438) under brand name Takecab, discovered by Takeda, is a new medicine for treating acid-related diseases with a novel mechanism of action called potassium-competitive acid blockers (P-CABs) which competitively inhibits the binding of potassium ions to H+,K+-ATPase (also known as the proton pump) in the final step of gastric acid secretion in gastric parietal cells. The drug is approved in Japan for the treatment of acid-related diseases, including gastric ulcer, duodenal ulcer, reflux esophagitis and Adjunct to Helicobacter pylori eradication in the case of Helicobacter pylori gastritis.

Pantoprazole is a proton pump inhibitor that inhibits gastric acid secretion and used for short-term treatment of erosive esophagitis associated with gastroesophageal reflux disease. Pantoprazole suppresses the final step in gastric acid production by covalently binding to the (H+, K+)-ATPase enzyme system at the secretory surface of the gastric parietal cell. This effect leads to inhibition of both basal and stimulated gastric acid secretion, irrespective of the stimulus. The binding to the (H+, K+)-ATPase results in a duration of antisecretory effect that persists longer than 24 hours. Pantoprazole is used for short-term treatment of erosion and ulceration of the esophagus for adults and pediatric patients 5 years of age and older caused by gastroesophageal reflux disease. It can be used as a maintenance therapy for long-term use after initial response is obtained, but there have not been any controlled studies about the use of pantoprazole past a duration of 12 months. Pantoprazole may also be used in combination with antibiotics to treat ulcers caused by Helicobacter pylori. Use of pantoprazole may increase the chance of developing infections such as pneumonia, particularly in hospitalized patients.

Rabeprazole was discovered by Eisai Co., Ltd. Janssen Pharmaceutica N.V. and Eisai Co., Ltd. have a strategic alliance in which Eisai and Janssen-Cilag co-promote the drug in Germany and the U.K. In the US rabeprazole sodium is co-promoted under the brand name AcipHex by Eisai Inc. and Janssen Pharmaceutica Inc. Pariet is available through Janssen-Cilag in most other countries excluding Japan and some Asian countries. Rabeprazole is an antiulcer drug in the class of proton pump inhibitors. Rabeprazole is a prodrug and is converted to the active sulphenamide form in the acid environment of the parietal cells. Rabeprazole is used to heal and maintain the healing of Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD), for healing Duodenal Ulcers, and for treatment of pathological hypersecretory conditions such as Zollinger-Ellison Syndrome. Rabeprazole suppresses gastric acid secretion by inhibiting the gastric H , K ATPase at the secretory surface of the gastric parietal cell and does not exhibit anticholinergic or histamine H2-receptor antagonist properties. Because this enzyme is regarded as the acid (proton) pump within the parietal cell, rabeprazole has been characterized as a gastric proton-pump inhibitor which blocks the final step of gastric acid secretion. In gastric parietal cells, rabeprazole is protonated, accumulates, and is transformed to an active sulfonamide.
