General Description

Benzeneacetic acid, 4-fluoro-.alpha.-(1-methylethyl)-, (.alpha.S)- is a chemical compound with the molecular formula C11H13FO2. It is also known as levofenac and is a nonsteroidal anti-inflammatory drug (NSAID) that is used to relieve pain and reduce inflammation. It works by inhibiting the production of prostaglandins, which are substances in the body that cause pain and inflammation. Levofenac is commonly prescribed for conditions such as osteoarthritis, rheumatoid arthritis, and acute pain. It is available in various forms, including tablets, injections, and topical gels, and is typically well-tolerated by most patients, although like all NSAIDs, it can cause side effects such as stomach upset and gastrointestinal bleeding.
