Description

Omeprazole CAS NO 73590-58-6 is a proton pump inhibitor (PPI) API, a substituted benzimidazole that acts as a potent and long-acting inhibitor of gastric acid secretion. This compound is critical for the formulation of effective and reliable gastrointestinal therapeutics. It is primarily required by pharmaceutical manufacturers for the production of solid dosage forms, such as delayed-release capsules and tablets, used in the treatment of acid-related disorders like gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome.

Application

• Pharmaceutical Active Ingredient (API): Core component in the manufacture of prescription and over-the-counter (OTC) anti-ulcer and anti-reflux medications.
• Delayed-Release Oral Formulations: Specifically used in enteric-coated tablets and capsules to ensure the API survives the acidic stomach environment and is released in the small intestine.
• Combination Drug Therapies: Utilized in fixed-dose combination products, for example, with antibiotics for Helicobacter pylori eradication regimens.
• Veterinary Pharmaceuticals: Applied in veterinary medicine for the treatment of gastric acid disorders in companion animals and livestock.
• Clinical Research: Serves as a reference standard and key material in pharmacokinetic, pharmacodynamic, and bioequivalence studies.
• Generic Drug Manufacturing: Essential for producers of generic omeprazole products, ensuring cost-effective access to this vital therapy globally.
