Description

Loxoprofen is a potent non-steroidal anti-inflammatory drug (NSAID) belonging to the propionic acid derivative class. This compound is valued for its effective analgesic and anti-inflammatory properties, making it a critical active pharmaceutical ingredient (API) in the formulation of prescription medications. It is primarily utilized by pharmaceutical manufacturers and research institutions focused on developing treatments for pain, inflammation, and fever associated with conditions like osteoarthritis and rheumatoid arthritis. Our supply of Loxoprofen CAS NO 50882-18-3 ensures high purity and reliable consistency for demanding pharmaceutical applications.

Application

• Pharmaceutical API: Primary use as the active ingredient in prescription analgesic and anti-inflammatory medications.
• Tablet Formulation: Used in the development and production of oral solid dosage forms for systemic delivery.
• Capsule Manufacturing: Incorporated into capsule formulations for precise dosing and patient compliance.
• Clinical Research: Serves as a reference standard and raw material in pharmacological studies and clinical trials.
• Generic Drug Production: A key component for manufacturers producing generic versions of branded NSAID drugs.
• Analytical Development: Used as a standard in HPLC, LC-MS, and other analytical methods for quality control and method validation.
