Description

Loxoprofen Sodium Salt is the sodium salt form of the potent non-steroidal anti-inflammatory drug (NSAID) loxoprofen. This active pharmaceutical ingredient (API) is valued for its effective analgesic and anti-inflammatory properties, offering a critical raw material for pharmaceutical manufacturing. It is primarily required by pharmaceutical companies and research institutions for the development and production of prescription and over-the-counter pain relief medications targeting conditions like arthritis, post-operative pain, and musculoskeletal disorders.

Application

• Pharmaceutical API: Primary use as the active ingredient in the formulation of solid oral dosage forms such as tablets and capsules.
• Analgesic Formulations: Manufacture of prescription and OTC medications for the relief of mild to moderate pain.
• Anti-inflammatory Medications: Key component in drugs designed to reduce inflammation associated with rheumatoid arthritis, osteoarthritis, and other inflammatory conditions.
• Post-operative Pain Management: Used in pharmaceutical preparations aimed at managing pain following surgical procedures.
• Musculoskeletal Disorder Treatments: Incorporated into therapies for back pain, sprains, and other soft tissue injuries.
• Research & Development: Serves as a reference standard and starting material in pharmacological research and new drug development projects.
• Generic Drug Production: Essential for manufacturers producing bioequivalent generic versions of loxoprofen-based medications.
