Description

Omeprazole CAS NO 119141-89-8 is a proton pump inhibitor (PPI) API, a key therapeutic agent for reducing gastric acid secretion. Its high purity and consistent quality are critical for ensuring the efficacy and safety of final pharmaceutical formulations. This active pharmaceutical ingredient is essential for manufacturers in the pharmaceutical industry producing treatments for acid-related disorders such as gastroesophageal reflux disease (GERD), peptic ulcers, and Zollinger-Ellison syndrome.

Application

• Pharmaceutical Formulations: Primary active ingredient in delayed-release capsules, tablets, and oral suspensions for acid suppression therapy.
• Generic Drug Manufacturing: Core component for producing bioequivalent generic versions of branded omeprazole medications.
• Combination Therapies: Used in fixed-dose combination products, for example with antibiotics for Helicobacter pylori eradication regimens.
• Hospital & Clinical Use: Formulated into injectable or soluble preparations for patients unable to take oral medications.
• Veterinary Pharmaceuticals: Applied in veterinary medicine for treating gastric ulcers in animals.
• Research & Development: Serves as a reference standard and starting material in pharmaceutical R&D for novel drug delivery systems.
