Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of medications used to relieve pain, inflammation, and fever. They are one of the most commonly used classes of drugs worldwide and are available over the counter or by prescription.
NSAIDs work by blocking the activity of the enzyme cyclooxygenase (COX), which is responsible for the production of prostaglandins. Prostaglandins are hormone-like substances that are involved in inflammation, pain, and fever. By reducing the production of prostaglandins, NSAIDs can relieve pain and inflammation.
There are two types of COX enzymes, COX-1 and COX-2. COX-1 produces prostaglandins that protect the stomach lining and regulate blood clotting, while COX-2 produces prostaglandins that cause inflammation and pain. Some NSAIDs inhibit both COX-1 and COX-2, while others are selective inhibitors of COX-2. Selective COX-2 inhibitors were developed to reduce the gastrointestinal side effects associated with traditional NSAIDs, which can inhibit both COX-1 and COX-2 and cause stomach ulcers and bleeding.
Common NSAIDs include aspirin, ibuprofen, naproxen, diclofenac, and celecoxib. NSAIDs are used to treat a variety of conditions, including arthritis, menstrual cramps, headache, dental pain, and post-operative pain.
NSAIDs can have potential side effects, such as gastrointestinal bleeding, kidney damage, and cardiovascular events, particularly when used at high doses or for prolonged periods. It is important to use NSAIDs as directed and under the guidance of a healthcare professional. In some cases, alternative treatments may be recommended to reduce the risk of side effects.
