L'aspirine et l'ibuprofène bloquent la production d'une classe de produits chimiques d'ajustages, appelées prostaglandines. Voyons comment ils font ça. Lorsque les cellules sont endommagées, elles libèrent une substance chimique appelée acide arachidonique.

Explanation:

We sense pain due to the transmission of a specific signal to the brain via the spinal cord. Pain relief medications work by preventing this 'pain signal' from reaching the brain. There are two main types of painkillers that are commonly used: the 'aspirin medicines' and the 'narcotic medicines.'

The Aspirin-type painkillers block the body's prostaglandins - molecules responsible for pain and swelling. Blocking prostaglandins blocks the signal at the source of the pain, as well as reducing swelling.

The Narcotic-type medicines block the pain messages in the spinal cord and the brain, and are typically used for much more severe pain relief.
