Paracetamol crystals,polarised light micrograph. Paracetamol is a painkiller (analgesic) drug widely used in over-the-counter medicines. It is thought to work by blocking the action of the enzyme COX-3,a cyclooxygenase,which is found in the central nervous system. Unlike aspirin and ibuprofen,which block all COX enzymes non- selectively,paracetamol does not have anti- inflammatory or antipyretic (fever-reducing) effects. It also does not irritate the stomach lining,as aspirin does | |
