萘普生 钠

Naproxen sodium (NS) is a sodium salt of propionic acid derivative and demonstrates analgesic, anti-pyretic, and anti-inflammatory properties. It exhibits efficiency in being used as an indomethacin in the treatment of acute musculoskeletal disorders. It belongs to the group of nonsteroidal anti-inflammatory drugs (NSAIDS) and acts by inhibiting the activity of both the cyclooxygenase enzymes, COX-1 & COX-2 and further blocking the synthesis of certain prostaglandins. It is administered in the treatment of ankylosing spondylitis, osteoarthritis, rheumatoid disorders, acute gout, mild to moderate pain, tendonitis, bursitis, dysmenorrhea, fever, and migraine headache. Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.

Naproxen sodium may be used as a pharmaceutical reference standard for the determination of the analyte in pharmaceutical formulations and combined dosage forms by chromatographic and spectrophotometric techniques.

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
