Overview
Ketoprofen is a widely used nonsteroidal anti-inflammatory drug (NSAID) known for its effectiveness in reducing pain, inflammation, and fever. It belongs to the propionic acid class of NSAIDs and is commonly prescribed for conditions like arthritis, musculoskeletal disorders, and post-operative pain. Its mechanism of action involves the inhibition of cyclooxygenase (COX) enzymes, which are responsible for prostaglandin synthesis. First introduced in the 1970s, ketoprofen has since become a staple in both human and veterinary medicine. It is available in various forms, including oral capsules, topical gels, and injectable solutions. The drug is favored for its rapid onset of action and relatively low incidence of side effects compared to other NSAIDs.
Physical and Chemical Properties
Ketoprofen is a white or off-white crystalline powder with a molecular weight of 254.28 g/mol. It has a melting point range of 94-97°C and is slightly soluble in water but more soluble in organic solvents like ethanol and acetone. The compound is stable under normal storage conditions but should be protected from light and moisture to prevent degradation. The molecular structure of ketoprofen includes a benzophenone moiety, which contributes to its anti-inflammatory properties. Its chemical stability makes it suitable for formulation into various pharmaceutical products, though care must be taken during handling to avoid inhalation or skin contact due to potential irritant effects.
Main Applications
Ketoprofen is primarily used to treat inflammatory conditions such as rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. It is also effective for managing acute pain, including dental pain, menstrual cramps, and post-surgical discomfort. In veterinary medicine, ketoprofen is used to alleviate pain and inflammation in animals, particularly in livestock and companion animals. Topical formulations of ketoprofen, such as gels and creams, are popular for localized pain relief, minimizing systemic side effects. The drug's versatility and efficacy have made it a key component in both prescription and over-the-counter medications worldwide.
Safety and Storage
Ketoprofen should be stored in a cool, dry place, away from direct sunlight and moisture, to maintain its stability. Proper handling is essential to avoid exposure; gloves and protective clothing are recommended when working with the powder form. The drug can cause gastrointestinal irritation, so it should be taken with food or milk to reduce stomach upset. Long-term use of ketoprofen may increase the risk of cardiovascular events and gastrointestinal bleeding, particularly in elderly patients. It is contraindicated in individuals with a history of hypersensitivity to NSAIDs or those with severe renal or hepatic impairment. Always follow prescribed dosages and consult a healthcare provider for guidance.
B2B Procurement Guide
When procuring ketoprofen in bulk, B2B buyers should prioritize suppliers who adhere to Good Manufacturing Practices (GMP) and provide certificates of analysis (CoA) to verify purity and composition. The reference price ranges from approximately $50 to $150 per kilogram, depending on quantity and purity. Buyers should also consider the form of ketoprofen needed (e.g., powder, granules) and ensure compatibility with their manufacturing processes. It is advisable to establish long-term relationships with reputable suppliers to ensure consistent quality and availability. Regulatory compliance, including adherence to pharmacopoeial standards (e.g., USP, EP), is critical for pharmaceutical-grade ketoprofen. Buyers should also assess logistics and storage capabilities to maintain product integrity during transit.
