Nifenazone is primarily used as an analgesic and anti-inflammatory agent, making it effective in managing pain and reducing inflammation associated with various conditions. It is commonly applied in the treatment of mild to moderate pain, such as headaches, muscle aches, and joint discomfort. Additionally, it is utilized to alleviate symptoms of rheumatic disorders and other inflammatory conditions.
