Cyclooxygenase-1 (COX-1) is an enzyme which is normally present in a variety of areas of the body, including sites of inflammation and the stomach. (medicinenet.com)
The COX-1 enzyme of the stomach produces certain chemical messengers (called prostaglandins) that ensure the natural mucus lining which protects the inner stomach. (medicinenet.com)
Common anti-inflammatory drugs like Aspirin block the function of the COX-1 enzyme along with another enzyme, COX-2 (see below). (medicinenet.com)
When the COX-1 enzyme is blocked, inflammation is reduced, but the protective mucus lining of the stomach is also reduced, which can cause stomach upset, ulceration, and bleeding from the stomach and intestines . (medicinenet.com)
Another enzyme, cyclooxygenase-2 (COX-2), also produces these chemical messenger molecules, but the COX-2 enzyme is located specifically in areas of the body that are responsible for inflammation and not in the stomach. (medicinenet.com)
When the COX-2 enzyme is blocked, inflammation is reduced. (medicinenet.com)
Since the COX-2 enzyme does not play a role in the normal function of the stomach or intestinal tract, medications which selectively block COX-2 do not present the risk of injuring the stomach or intestines. (medicinenet.com)
