Riding a bicycle, a 31 year old male, fell into a trench. This freak accident leads to a fracture in his leg. A cast was put around his broken bone and nonsteroidal anti-inflammatory drugs (NSAIDs) prescribed to relieve the pain. NSAIDs is a group of medications that are most widely used around the world. However, most of them have potential side-effects known to all. It is very important to note the benefits as well as the adverse effects of these easily available over-the-counter drugs.

What is Nonsteroidal Anti-inflammatory Drugs?

Non-steroidal anti-inflammatory drugs or NSAIDs are commonly used drugs that have an analgesic and antipyretic effect. These drugs are different from steroids and have anti-inflammatory effect. These pain killers effectively reduce the discomfort without having any narcotic or drowsy effect. The most commonly available NSAIDs include aspirin, ibuprofen and naproxen.

How Do Nonsteroidal Anti-inflammatory Drugs Work?

NSAIDs help in relieving pain, inflammation as well as fever. These drugs tend to reduce the production of a hormone called prostaglandins. This hormone plays a role in inflammation, fever and pain. On the other hand, prostaglandins also help in protecting the stomach lining from the effects of acids.

There are two types of cyclooxygenase (COX) enzymes that produce prostaglandins. COX-1 and COX-2 both produce the type of prostaglandins that have different functions in the body.   COX-1 is the type that produces prostaglandins that play a role in protection of the stomach lining. COX-2 is the type that produce prostaglandins that play a role in fever, pain and inflammation.

NSAIDs act on cyclooxygenase enzymes and block it from producing prostaglandins. Thus, helps in reducing pain, inflammation and fever. However, it also blocks COX-1, thus, leading reduce clotting acting, development of ulcers in the stomach, nausea, bruising and other side effects.

Are There NSAIDs That Specifically Block COX-2?

There are special drugs that act only on COX-2. They target COX-2 enzyme and help in the reduction of inflammation. These drugs do not lead to ulcers as they do not act on COX-1 enzyme . However, these drugs have a reduced effect in protecting one against heart diseases.

One should keep in mind, if they are taking COX-2 inhibitor NSAIDs, then they should never team along with the normal NSAIDs. Also, these drugs are not free from side effects. They lead to abdominal pain, nausea, upset stomach, etc.

Examples for specific COX-2 inhibitor is celecoxib
