Delanzo DDR 30 mg is a medication that contains dexlansoprazole, a proton pump inhibitor (PPI). It works by reducing the amount of acid produced in the stomach, helping treat conditions like gastroesophageal reflux disease (GERD) and erosive esophagitis. The DDR (Dual Delayed Release) formulation of this drug allows for two distinct releases of the medication, enhancing its effectiveness. Delanzo DDR is typically prescribed to heal and maintain the healing of erosive esophagitis, relieve symptoms of GERD, and improve overall digestive health. It is usually taken once daily, with or without food, and should be swallowed whole. Like other PPIs, it may have some side effects such as headache, diarrhea, or abdominal pain, and long-term use should be monitored by a healthcare provider due to potential risks like vitamin B12 deficiency or bone fractures.
