Dexend 30 mg is a delayed-release proton pump inhibitor (PPI) containing dexlansoprazole, the R-enantiomer of lansoprazole. It is formulated with dual delayed-release (DDR) technology, utilizing two types of enteric-coated granules that dissolve at different pH levels. This design allows for extended acid suppression by releasing the medication in two phases, enhancing its effectiveness in reducing gastric acid secretion.
