ibuprofen

In medicine, a non-steroidal anti-inflammatory drug (NSAID) that is used to relieve pain and inflammation.

Ibuprofen acts by inhibiting the formation of prostaglandins that mediate inflammation and so is used to treat conditions that are characterized by pain and inflammation, such as arthritic conditions, dental pain, period pain, sprains, and sports injuries. It is usually taken by mouth. Adverse effects include irritation of the gut, which can be reduced by taking ibuprofen at the same time as food. It should not be taken by patients with gastric ulceration and caution is required in patients with allergic disorders. Creams and gels are available that can be applied directly to the inflamed area. Ibuprofen can also slow the development of Alzheimer's disease, but only at high doses that can be toxic.
