REALPAN-40 is a commonly used proton pump inhibitor (PPI) designed to reduce the production of stomach acid. It is typically prescribed for individuals suffering from conditions like gastroesophageal reflux disease (GERD), peptic ulcers, or Zollinger-Ellison syndrome. By inhibiting the proton pumps in the stomach lining, REALPAN-40 helps prevent acid reflux, stomach discomfort, and the formation of ulcers, promoting healing of the gastrointestinal tract. This medication is effective in relieving symptoms like heartburn, acid regurgitation, and bloating. For best results, it is recommended to take REALPAN-40 before meals, typically in the morning, as part of a daily regimen. While it is generally well-tolerated, long-term use of PPIs should be done under medical supervision due to the potential for side effects such as vitamin B12 deficiency or increased risk of infections.
