Oral Suspension contains ibuprofen as the prime ingredient. Ibuprofen helps to relieve pain and inflammation.
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 cause pain. 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.
