Full-Cycle Quality Control & Consistent Quality
Quality is the core competitiveness of nonsteroidal anti-inflammatory API. We enforce internal standards higher than pharmacopoeial requirements across synthesis, crystallization and purification, with strict control of crystal form, moisture and impurities. As professional China Loxoprofen Sodium Dihydrate manufacturers, we deliver stable and reliable quality.
Stable crystallization process
Precise temperature and humidity control ensures the API forms consistent dihydrate crystals without mixed crystals or dehydration. High batch-to-batch consistency provides a reliable basis for formulation development.
Sustained high purity
Process impurities, heavy metals and residual solvents are tightly monitored at each stage. Long-term batch data remain stable, meeting high-purity demands for external and oral preparations. Loxoprofen Sodium Dihydrate made in China fully complies with mainstream pharmacopoeial standards.
Stable physicochemical properties
With low hygroscopicity and mild properties, Loxoprofen Sodium Dihydrate powder is resistant to decomposition and discoloration under normal storage and transport, ensuring consistent quality for further processing.
Traceable batch data for scalable production: A complete traceability system regulates moisture, assay and particle size. With minimal batch variation, it reliably supports large-scale production of tablets and patches. We supply premium Bulk Loxoprofen Sodium Dihydrate with consistent quality.
Pharmacopoeial compliance: Full-cycle testing is performed in line with international pharmacopoeial requirements. Processes are continuously optimized to ensure stable quality for R&D registration and commercial supply.
Application Scenarios
NSAID pharmaceutical API is mainly used in anti-inflammatory, analgesic and antipyretic drugs, covering orthopedics, rheumatology and postoperative pain treatment,with specific scenarios including:
Oral solid preparations:
Suitable for tablets, capsules, granules and other oral solid dosage forms. With high purity and good fluidity, the material ensures stable dissolution and meets the needs of large-scale production.
External analgesic preparations:
Applicable to gels, creams, patches and liniments. Uniform particle size and good solubility enhance transdermal absorption, with stable quality and no irritant impurities.

Pharmacological, toxicological and pharmacodynamic studies:
High purity and low impurity make it ideal for activity evaluation, safety tests and efficacy research, reducing experimental interference with excellent batch consistency.

Stable quality lowers application risks and supports smooth approval. We also offer Loxoprofen Sodium Dihydrate free sample for your evaluation.
Packaging and Transportation
NSAID API is sensitive to temperature, humidity and light, making it prone to physical changes. We have therefore developed a dedicated packaging and transportation protection system to maintain stable product quality from production to delivery. As a professional China Loxoprofen Sodium Dihydrate factory, we implement strict storage and transportation control:
Standard packaging specifications:
Pharmaceutical-grade sealed packaging is adopted, with regular options of 1kg, 5kg and 25kg. Moisture-proof aluminum foil and PE bags are used as inner layers, paired with hard fiber drums, effectively isolating moisture and impact to keep the API stable during storage.
Moisture-proof sealing:
Desiccants are built in and strict sealing is applied to prevent crystal alteration caused by moisture. The packaging meets transportation standards, featuring compression resistance and leak prevention to avoid damage, leakage or contamination during handling.
Standardized transportation:
The product is shipped at room temperature and protected from light, with controlled temperature and humidity to avoid exposure and extreme temperature changes. Protective measures ensure no moisture absorption or degradation, with consistent quality upon arrival.
