Proquazone is primarily used as an anti-inflammatory and analgesic agent, making it effective in the treatment of conditions involving pain and inflammation, such as arthritis, musculoskeletal disorders, and other rheumatic diseases. It works by inhibiting the synthesis of prostaglandins, which are compounds in the body that contribute to inflammation and pain. Due to its therapeutic properties, it is often prescribed to alleviate symptoms like swelling, stiffness, and joint pain, improving mobility and quality of life for patients. However, its use has declined in some regions due to the availability of newer medications with fewer side effects.
