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.
You should also avoid taking Advil if you are taking Aspirin to prevent stroke or heart attack. If the physician advises to take both, Advil should be taken at least 8 hours before or 30 minutes after you take Aspirin. Use of Alcohol while taking Advil is also prohibited because it may increase risk of stomach bleeding.
