Compositions of non-steroidal anti-inflammatory drugs decongestants and anti-histamines

Abstract

The present invention is directed to a pharmaceutical composition and a method for the treatment of rhinitis and cold-like symptoms which includes a non-steroidal anti-inflammatory drug (NSAID), a decongestant, and an antihistamine. It has been found that the NSAID enhances the activity of a decongestant and an anti-histamine, thus permitting a reduction in either or both in administration of separate dosage forms. The same enhancement can also occur with an anti-tussitive. Thus, the effective amount of the decongestant or the antihistamine or both is less than about 75 % of an amount presentin an approved dose of the decongestant or the antihistamine, or both, relative to an amount of the NSAID corresponding to about 100% of the amount present in a normal strength dosage form of the NSAID.
