4105-91-3 Usage
General Description
1-(p-Aminophenyl)-3-ethoxy-2-pyrazolin-5-one is a chemical compound with the molecular formula C11H12N2O2. It is commonly known as Etoricoxib and is used as a nonsteroidal anti-inflammatory drug (NSAID) to relieve pain and inflammation in conditions such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, and gout. Etoricoxib works by inhibiting the production of prostaglandins, which are hormone-like substances that contribute to inflammation, pain, and fever in the body. It belongs to the class of selective COX-2 inhibitors, which means it targets the specific enzyme responsible for producing prostaglandins, leading to reduced pain and inflammation. Etoricoxib is available in oral tablet form and is typically prescribed by healthcare professionals for short-term use. Like other NSAIDs, it can have side effects such as stomach ulcers, kidney problems, and cardiovascular complications, so it should be used with caution and under medical supervision.
