They are recommended to treat a number of ailments from aches and pains to fevers. While you may have taken them a number of times, you might not know exactly what NSAIDs are exactly. This article will reveal everything you should know about these common drugs.

What Are NSAIDs?

How Do NSAIDs Work?

There is a wide range of NSAIDs that fall into a variety of classes, but they all tend to have the same effects. They reduce fevers, inflammation, and pain in similar ways. How they actually work is a more complex process.

Prostaglandins in the body affect the inflammatory response in the body. These prostaglandins are necessary to help the body through inflammation. With an increase in inflammation, however, there is also an increase in pain and fever. The more prostaglandins in the body, the more inflammation an individual will suffer from. NSAIDs work to slow down the process of prostaglandin formation. This is achieved when the compounds of the NSAIDs drug work to block the cyclooxygenase enzymes or COX. Since COX enzymes increase the production of prostaglandins, when blocked by the NSAIDs, there is a reduction in prostaglandins and therefore and reduction in inflammation.

There are two types of COX enzymes. COX 1 enzymes protect the stomach and maintain proper kidney functioning. COX 2 enzymes are produced when there is an injury to the joints or they become inflamed. When asking "what are NSAIDs", you will need to consider the effect they have on these COX enzymes. NSAIDs typically block both COX 1 and 2 enzymes, but there are certain NSAIDs that target only the COX 2 enzymes.

COX enzymes also have an effect on the blood platelets. When NSAIDs block the COX enzymes, they also have an anti-clotting effect on the blood cells. These enzymes also help protect the stomach, so NSAIDs can have a negative effect since they block the enzymes from functioning properly.

What Are NSAIDs Used to Treat?

NSAIDs can be typically bought over the counter to treat minor ailments. Prescription NSAIDs can also be obtained to help treat more serious conditions. While they are used to treat a number of condition, some of the most common conditions NSAIDs are used to treat include:

  • inflammation
  • pain
  • fever

A NSAID may also be prescribed to help prevent artery disease. In low doses, NSAIDs can reduce the risk of stroke or heart attack. Aspirin, the most widely known NSAID, is used to treat most conditions. It is also the most effective NSAID that inhibits blood clotting for the longest period of time, up to seven days. For this reason, aspirin is often recommended in low dosages to prevent heart attack or stroke.
