Breaking these large molecules into smaller components involves: 1  movement: propels food through the digestive system. 2  secretion: release of digestive juices in response to a specific stimulus. 3  digestion: breakdown of food into molecular components small enough to cross the plasma membrane.
Over-the-counter pain relievers, like Advil (ibuprofen), Aleve (naproxen sodium) and Tylenol (acetaminophen), are presumed to be safe. Since they don't require a prescription, directions and warnings aren't always taken seriously.
It is not necessary to take AdvilÂ® with food, however, take it with food or milk if an upset stomach occurs. Consult your physician before taking any NSAID or if you have a history of stomach problems such as heartburn, upset stomach or stomach pain.
