Etoricoxib API [CAS No. 202409-33-4]
Molecular Formula:C18H15ClN2O2S
Molecular Weight:358.84
Description
Etoricoxib is a selective COX-2 (cyclooxygenase-2) inhibitor classified as a non-steroidal anti-inflammatory drug (NSAID). Etoricoxib is universally used for its anti-inflammatory, analgesic, and antipyretic properties. Etoricoxib functions as a selective cyclooxygenase-2 (COX-2) inhibitor, providing effective relief from pain and inflammation associated with conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gouty arthritis. By blocking the COX-2 enzyme, it reduces the production of prostaglandins, which are the chemical messengers responsible for pain and swelling, while potentially causing fewer stomach problems compared to traditional non-selective NSAIDs. We are leading & trusted Etoricoxib suppliers worldwide, offering high-purity Etoricoxib that meets US/EU quality and safety standards, with reliable lead times and global supply capability.
