Invigan Indication
For the treatment of peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD).
Invigan Pharmacology
Famotidine, a competitive histamine H2-receptor antagonist, is used to treat gastrointestinal disorders such as gastric or duodenal ulcer, gastroesophageal reflux disease, and pathological hypersecretory conditions. Famotidine inhibits many of the isoenzymes of the hepatic CYP450 enzyme system. Other actions of Famotidine include an increase in gastric bacterial flora such as nitrate-reducing organisms.
Invigan Absorption
The bioavailability of oral doses is 40-45%.

Invigan Patient Information
Famotidine is used to treat stomach and duodenal (upper small intestine) ulcers;
hypersecretory (increased acid secretion) conditions; heartburn and gastroesophageal
reflux disease (stomach contents bubbling into the esophagus causing pain). Notify your
physician if you are pregnant or nursing. Famotidine may be taken with or without food.
