Team Health Cages


Ibuprofen is a common medicine that belongs to a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). People often use it to ease pain, reduce swelling, and bring down a fever. 

In this blog, we’ll discuss these topics:

What is Ibuprofen?

Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to reduce fever, relieve pain, and decrease inflammation. It works by inhibiting enzymes involved in the production of prostaglandins, which contribute to inflammation and pain in the body. Ibuprofen is often used for headaches, menstrual cramps, muscle aches, arthritis, and other conditions. It is available over the counter and in prescription strengths.

How Does Ibuprofen Work?

Ibuprofen works by inhibiting the activity of enzymes called cyclooxygenases (COX-1 and COX-2). These enzymes are responsible for producing prostaglandins, which are compounds that promote inflammation, pain, and fever. By blocking COX enzymes, ibuprofen reduces the production of prostaglandins, thereby decreasing inflammation, alleviating pain, and lowering fever.
