Description

Fenoprofen Calcium is a non-steroidal anti-inflammatory drug (NSAID) belonging to the propionic acid derivative class. Its primary value lies in its potent analgesic and anti-inflammatory properties, making it a critical active pharmaceutical ingredient (API) for therapeutic formulations. This compound is essential for pharmaceutical manufacturers developing prescription medications to manage pain and inflammation associated with conditions like arthritis and other musculoskeletal disorders.

Application

• Primary use as an Active Pharmaceutical Ingredient (API) in the manufacture of prescription analgesic and anti-inflammatory medications.
• Formulation of oral solid dosage forms, including tablets and capsules, for the management of mild to moderate pain.
• Key component in drugs prescribed for the symptomatic relief of rheumatoid arthritis and osteoarthritis.
• Used in pharmaceutical R&D for developing new drug delivery systems and combination therapies.
• Reference standard in analytical laboratories for quality control and method development (HPLC, spectroscopy).
