Advil is a brand name for the drug ibuprofen, which is a nonsteroidal anti-inflammatory drug (NSAID) that works by reducing hormones that cause inflammation and pain in the body [3]. Advil has recently introduced a new formula called Advil Dual Action, which combines ibuprofen and acetaminophen to provide relief for pain and fever. The combination of these two drugs has been shown to be more effective than taking either drug alone [2].

Ibuprofen, the active ingredient in Advil, is a white crystalline powder that is slightly soluble in water and freely soluble in ethanol [3]. It is classified as a nonsteroidal anti-inflammatory drug (NSAID) and works by inhibiting the production of prostaglandins, which are responsible for inflammation and pain [3]. Ibuprofen is used to relieve pain, reduce fever, and treat inflammation [3].

Acetaminophen, the other active ingredient in Advil Dual Action, is a white crystalline powder that is also slightly soluble in water and freely soluble in ethanol [2]. It works by inhibiting the production of prostaglandins in the brain, which reduces pain and fever [2]. Acetaminophen is used to relieve pain and reduce fever [2].

In summary, the new Advil Dual Action formula contains a combination of ibuprofen and acetaminophen, which work together to provide relief for pain and fever. Ibuprofen is a nonsteroidal anti-inflammatory drug that works by reducing hormones that cause inflammation and pain, while acetaminophen works by inhibiting the production of prostaglandins in the brain, which reduces pain and fever.
