Used primarily as an analgesic and antipyretic in some over-the-counter medications, especially in ear drops for treating ear pain associated with otitis media. It helps reduce inflammation and discomfort in the ear when combined with benzocaine. Also employed in research settings to assess liver function due to its metabolism profile, reflecting hepatic enzyme activity. Has been utilized in veterinary medicine for similar pain and fever relief purposes. Limited use in modern systemic medications due to the development of safer alternatives, but remains in topical and diagnostic applications.
