What is the primary active ingredient in the over-the-counter medication Advil?

The primary active ingredient in the over-the-counter medication Advil is ibuprofen. This nonsteroidal anti-inflammatory drug (NSAID) is widely used for its analgesic (pain-relieving) and anti-inflammatory properties. It works by inhibiting enzymes involved in the production of prostaglandins, which are substances that mediate inflammation and pain in the body.

Given its specific mechanism of action, ibuprofen is effective in treating symptoms such as headaches, muscle aches, menstrual cramps, and other minor aches and pains. It is important for consumers to recognize ibuprofen as the active ingredient, especially since there are other common over-the-counter medications, like acetaminophen and aspirin, which serve different purposes and belong to distinct classes of medications. Understanding ibuprofen's role helps individuals choose the appropriate medication based on their specific health needs.
