Advil Dual Action is a new formula of Advil that claims to provide relief from pain faster and longer than regular Advil. The product combines ibuprofen and acetaminophen to target pain in two different ways. Ibuprofen reduces inflammation, while acetaminophen blocks pain signals in the brain [2].

According to the drug patent watch, the patent for the Advil Dual Action formula was filed in 2016 and granted in 2019 [1]. This suggests that the formula is relatively new and has not been on the market for very long.

A study published in the Journal of Pain Research compared the efficacy of Advil Dual Action to regular Advil in treating dental pain. The study found that Advil Dual Action provided faster and more sustained pain relief than regular Advil [3]. However, it is important to note that this study only looked at the effectiveness of the product in treating dental pain and may not be representative of its effectiveness in treating other types of pain.

Overall, the available evidence suggests that Advil Dual Action is an effective pain reliever that may provide faster and more sustained relief than regular Advil. However, more research is needed to determine the product's effectiveness in treating other types of pain and to assess its long-term safety and efficacy.
