Feminax express tablets contain the active ingredient ibuprofen lysine, which is a type of medicine called a non-steroidal anti-inflammatory drug (NSAID). Ibuprofen is a simple painkilling medicine used to relieve mild to moderate pain, inflammation and fever. Ibuprofen is also available without a brand name, ie as the generic medicine.
Ibuprofen works by blocking the action of a substance in the body called cyclo-oxygenase (COX). Cyclo-oxygenase is involved in the production of various chemicals in the body, some of which are known as prostaglandins. Prostaglandins are produced in response to injury and certain diseases and conditions, and cause pain, swelling and inflammation. NSAIDs block the production of these prostaglandins and are therefore effective at reducing inflammation and pain.
Ibuprofen also reduces fever by reducing the production of prostaglandins. Fever is associated with an increase in prostaglandins in the brain, and these prostaglandins cause the body temperature to increase. By reducing prostaglandins in the brain, ibuprofen lowers body temperature and hence reduces fever.
Ibuprofen lysine is a form of ibuprofen that is more soluble than regular ibuprofen. This means that it starts to work more quickly than regular ibuprofen tablets/caplets.
