Abstract
The present invention provides a technique that allows a pharmaceutical composition, preferably for external use, containing luliconazole or the like to contain luliconazole or the like at a high concentration, and suppresses the precipitation thereof over time. The present invention uses a polyethylene glycol having an average molecular weight of 380 to 420 represented by a formula HOCH(CHOCH)CHOH (where n is an integer), ethanol, benzyl alcohol, lactic acid, propylene carbonate, and acetone in combination with the luliconazole or the like.
