The mechanism of Pepcid involves blocking histamine-2, which leads to a reduction in the production of stomach acid.
Pepcid is indicated for the treatment and prevention of ulcers in the stomach and intestines. Additionally, it is prescribed for conditions characterized by excessive stomach acid secretion, such as Zollinger-Ellison syndrome.
Furthermore, Pepcid is used for treating gastroesophageal reflux disease (GERD) and other disorders where stomach acid flows back into the esophagus and causes heartburn.
