Disclosed is an external preparation containing nonsteroidal anti-inflammatory drugs (NSAIDs), which is suppressed in cytotoxicity induced by the NSAIDs. Also disclosed is a method for producing the external preparation. The present invention is based on the finding that skin disorders induced by nonsteroidal anti-inflammatory drugs (NSAIDs) can be suppressed when the NSAIDs form intermolecular compounds together with trehalose, which is an example of disaccharides. A disaccharide other than trehalose may be used therefor.
