In the past several years, some newer medications have come on the market; these are commonly referred to as COX-2 inhibitors . Remember, all NSAIDs work against cyclooxygenase (COX). Traditional NSAIDs (. Ibuprofen, Motrin, Aleve) work against both COX-1 and COX-2. COX-1 and COX-2 are both types of cyclooxygenase enzymes that function in your body. The new medications (. Celebrex) work primarily against COX-2, and allow COX-1 to function normally. Because COX-1 is more important in producing the protective lining in your gut (gastric mucosa), these newer NSAIDs are believed to have less of a risk of causing stomach ulcers.
When and how much to take
NSAIDs should ideally be taken with some food, or at least with milk or yoghurt to avoid irritation of the gastric mucosa (. the inner lining of the stomach). It is important not to exceed the recommended dose to avoid possible serious side-effects. There is also no benefit in taking more than a certain dose, since these drugs have a ceiling effect. This means that above a certain dose, taking even more of this medication will not yield any extra beneficial effects, but will considerably increase the risk for side-effects.
