Dexlansoprazole Sesquihydrate
Dexlansoprazole Sesquihydrate is the active enantiomer of lansoprazole and belongs to a class of medications known as proton pump inhibitors (PPIs). It works by blocking the acid-producing pumps in the stomach lining, reducing the amount of acid that is produced. This medication is primarily used to treat conditions involving excessive stomach acid, such as gastroesophageal reflux disease (GERD) and erosive esophagitis.
Dexlansoprazole Sesquihydrate is a proton pump inhibitor that reduces stomach acid production to treat acid-related conditions like GERD and heartburn.

Treatment of gastroesophageal reflux disease (GERD), maintenance therapy for healed erosive esophagitis, and relief of heartburn symptoms associated with GERD. It may also be used for other acid-related conditions as determined by a healthcare provider.
As a proton pump inhibitor, dexlansoprazole works by irreversibly blocking the H+/K+ ATPase enzyme system (the gastric acid pump) in the parietal cells of the stomach lining. This action suppresses the final step of acid production, significantly reducing gastric acid secretion.
Should be taken as prescribed, typically once daily. May interact with certain medications affecting absorption. Long-term use should be monitored by a healthcare professional. Common side effects may include headache, diarrhea, and abdominal pain. Patients should inform their doctor of their full medical history before use.
