Nurofen is the brand name of a range of pain-relief medication made by Boots Healthcare, recently acquired by UK drug company Reckitt Benckiser.
There are eleven variants of Nurofen which all contain the analgesic ibuprofen, which was developed by the research arm of Boots, as the active ingredient. Some variants contain other active ingredients, for example Nurofen Cold & Flu contains the non-sedating decongestant pseudoephedrine.
