Overview
Omeprazole sodium (CAS 95510-70-6 ) is the sodium salt form of omeprazole, commonly referenced in procurement as Losec Sodium. It functions as a proton pump inhibitor active pharmaceutical ingredient, suppressing gastric acid secretion.
This compound serves as the basis for injectable and solid oral dosage formulations. The primary application is in parenteral formulations, where the sodium salt form offers improved aqueous solubility compared to the free base.
This enhanced solubility enables IV and infusion preparations for hospital use. It is also used in the manufacture of enteric-coated tablets and capsules targeting gastroesophageal reflux disease and peptic ulcer treatment.
Pharmaceutical manufacturers sourcing this material for generic drug production rely on it as a direct API input requiring full regulatory documentation. It is a critical component for high-volume pharmaceutical manufacturing.
Contract formulators developing combination gastric products may also specify this form when targeting rapid-onset delivery profiles. The material ensures consistency across various therapeutic delivery systems and clinical applications.
Omeprazole sodium is supplied as a white to off-white crystalline powder. It is available in pharmaceutical-grade specifications aligned with USP and BP monograph requirements for API use.
Packaging is typically offered in controlled, moisture-protected formats suited to GMP manufacturing environments. This ensures the stability and integrity of the chemical during long-term storage and international transport.
