Paracetamol belongs to a group of medicines known as analgesics, or painkillers. It is used to relieve mild to moderate pain. It is also useful for lowering a raised temperature (fever), such as during a cold or after childhood immunizations. Paracetamol is often recommended as one of the first treatments for pain, as it’s safe for most people to take and side effects are rare.
Mechanism of Action
The mechanism of action of paracetamol is not completely understood. Unlike other NSAIDs, paracetamol does not to inhibit the function of any cyclooxygenase (COX) enzyme outside the central nervous system, and this appears to be the reason why it is not useful as an anti-inflammatory. It does appear to selectively inhibit COX activities in the brain, which may contribute to its ability to treat fever and pain. This activity is not likely to directly inhibit by blocking an active site, but rather by reducing COX, which must be oxidized in order to function.
