Description

Famotidine CAS NO 76824-35-6 is a potent and selective histamine H₂-receptor antagonist, widely recognized for its role in inhibiting gastric acid secretion. This high-purity active pharmaceutical ingredient (API) is critical for ensuring the efficacy and safety of finished pharmaceutical formulations. It is primarily utilized by pharmaceutical manufacturers in the production of medications for the treatment and prevention of peptic ulcers, gastroesophageal reflux disease (GERD), and other acid-related gastrointestinal disorders.

Application

• Active Pharmaceutical Ingredient (API) in prescription and over-the-counter anti-ulcer medications.
• Core component in solid oral dosage forms such as tablets and capsules for the treatment of duodenal and gastric ulcers.
• Key therapeutic agent in formulations for gastroesophageal reflux disease (GERD) and Zollinger-Ellison syndrome.
• Used in injectable solutions for hospital settings where rapid acid suppression is required.
• Intermediate in the research and development of new gastrointestinal therapeutics.
• Reference standard in analytical laboratories for quality control and pharmaceutical testing.
