Many people attribute the stuffiness associated with the cold or the flu to an increase in mucus which blocks their airways. While it is true that increased mucus is a symptom of the common cold, it is not always what makes you feel so stuffed up. Instead, the true source of nasal and sinus congestion is often caused by inflammation of the tissues throughout the nose and face making it harder to breath. When the body identifies a virus it deems threatening, its defenses spring into action in various ways, one of which is by causing the airways within the nose and sinuses and to swell and become inflamed. Hence, the best way to treat congestion is to reduce the inflammation that causes it. Advil® Cold & Sinus addresses this problem through the use of an effective decongestant, pseudoephedrine. Pseudoephedrine works by releasing norepinephrine, a form of adrenaline, which affects the tiny muscles lining the walls of blood vessels, causing them to constrict or close. This process, called vasoconstriction, serves to re-open vital airways and allows the cold-sufferer to breathe easier.
Advil® Cold & Sinus also contains ibuprofen, a common painkiller that can relieve the pain associated with the common cold, and the flu. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that is an effective pain reliever used to reduce headaches, treat soreness and eliminate pain throughout the body. It acts by inhibiting the COX enzyme responsible for the production of inflammatory mediators and hence interrupts the process that leads to inflammation, congestion, and hyper-sensitive nerve endings to which some people perceive as effective pain relief.
Thus, taking Advil® Cold & Sinus can help alleviate your discomfort from your swollen nose and sinuses making you feel less pain.
