Research on storage stability differences between ceftriaxone sodium products.

Area of Science:

• Pharmaceutical Science
• Solid-State Chemistry

Background:

• Ceftriaxone sodium is a widely used antibiotic.
• Ensuring the stability and efficacy of ceftriaxone sodium products is crucial for patient safety.
• Differences in stability between generic and brand-name ceftriaxone sodium formulations require investigation.

Purpose of the Study:

• To investigate the conditions and mechanisms causing stability differences in ceftriaxone sodium products.
• To understand how pharmaceutical processes influence the stability of ceftriaxone sodium preparations.
• To identify optimal storage conditions for generic ceftriaxone sodium.

Main Methods:

• Powder X-ray diffraction (PXRD) was employed to analyze crystal structure.
• Thermogravimetric analysis (TGA) assessed thermal properties and water content.
• Samples were exposed to varying humidity and high-temperature conditions to simulate storage.

Main Results:

• Humidity changes caused reversible hydrate redistribution in generic ceftriaxone sodium, affecting stability.
• High temperatures led to irreversible hydrate distribution in generic products.
• Brand-name ceftriaxone sodium remained stable at 40°C, while generics showed instability.

Conclusions:

• Generic ceftriaxone sodium stability is sensitive to hydrate dynamics.
• Controlled sealing and cool storage conditions are recommended for generic ceftriaxone sodium powder preparations.
• Adhering to these storage guidelines will ensure the efficacy and stability of generic ceftriaxone sodium.
