2060312 9015605 PCTABS00002 Commercially available antitussives which are widely used at present are problematic in that they contain dihydrocodeine which is officially designated as a narcotic or methylephedrine which is used as a starting material for a stimulant. An antitussive composition of the invention comprises a combination of an antitussive and L-tryptophan to enhance the antitussive effect. It has a similar antitussive effect even though the content of the antitussive is reduced, and is free from the side effect of aggravating the physical dependence of an antitussive.
