Description

Ketoprofen Lysinate is the lysine salt form of the non-steroidal anti-inflammatory drug (NSAID) ketoprofen, enhancing its solubility and bioavailability. This compound is a critical active pharmaceutical ingredient (API) used in the formulation of fast-acting analgesic and anti-inflammatory medications. It is primarily required by pharmaceutical manufacturers for the production of oral and topical preparations targeting pain and inflammation management.

Application

• Pharmaceutical API: Primary use as the active ingredient in solid oral dosage forms such as tablets and capsules.
• Fast-Dissolving Formulations: Ideal for orally disintegrating tablets (ODTs) and other rapid-release drug delivery systems due to its enhanced solubility.
• Topical Analgesics: Used in the manufacture of gels, creams, and patches for localized pain relief.
• Veterinary Medicine: Formulated for anti-inflammatory and analgesic treatments in animals.
• Analgesic Preparations: For the management of mild to moderate pain, including musculoskeletal pain and dysmenorrhea.
• Anti-inflammatory Therapeutics: For conditions such as osteoarthritis and rheumatoid arthritis.
