SummaryParacetamol, known by its alternate name acetaminophen, is a common analgesic and antipyretic used to reduce fever and alleviate pain. Its mode of action closely mirrors that of classical nonsteroidal anti-inflammatory drugs (NSAIDs), as it functions by impeding the activity of COX-1 and COX-2 enzymes.Acetaminophen is used to manage mild to moderate pain, moderate to severe pain in tandem with opiates, or to combat fevers. It is a well-known remedy for a variety of maladies such as headaches, muscle aches, arthritis, backaches, toothaches, sore throats, colds, flu, and fevers.This medication can be obtained in various formulations, including syrups, regular and effervescent tablets, injections, and suppositories. Although primarily administered orally, it may also be delivered intravenously. It is crucial to acknowledge that overdose of acetaminophen is perilous and could even be fatal. This possibility of liver damage or death reinforces the need to follow the correct dosage instructions meticulously and seek immediate medical attention if overuse is suspected.Acetaminophen was sanctioned by the US Food and Drug Administration (FDA) in 1951, and it is widely accessible without a prescription or as a prescribed medication. |
