The present invention provides a pharmaceutical composition for application to the mucosa to be used in drug therapy comprising a water-insoluble and/or water-low soluble substance, ciclesonide, and an aqueous medium, and having an osmotic pressure of less than 290 mOsm. This composition is superior over conventional pharmaceutical compositions for application to the mucosa, due to efficient and high ciclesonide retentivity and permeability to the submucosa or the blood at the mucosa.
