Etrosa 90mg Tablet contains Etoricoxib, a selective COX-2 inhibitor used primarily for the management of pain and inflammation associated with various musculoskeletal conditions. It is commonly prescribed for osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and acute gouty arthritis, providing effective relief from joint pain, swelling, and stiffness. Etoricoxib works by selectively blocking the cyclooxygenase-2 enzyme, which plays a key role in the inflammatory process, thereby reducing the production of prostaglandins responsible for pain and inflammation. This targeted action helps minimize gastrointestinal side effects often seen with traditional nonsteroidal anti-inflammatory drugs (NSAIDs). Etrosa 90mg is typically taken once daily, with or without food, as directed by a healthcare professional. It is important to use this medication under medical supervision, especially in patients with a history of cardiovascular disease, hypertension, or gastrointestinal disorders, as it may increase the risk of adverse effects in these populations. Patients should avoid concurrent use with other NSAIDs and inform their doctor about any other medications they are taking to prevent potential drug interactions. Etrosa 90mg offers a convenient and effective option for managing chronic inflammatory conditions and improving quality of life.
