The invention provides a pharmaceutical composition comprising a hydrophobic active ingredient and a surfactant, which have a hydrophobic end and a hydrophilic end; an acidic ingredient; and a foaming agent. Among them, the acid component and the foaming agent are dissolved in water and react to generate carbon dioxide gas, the hydrophobic end of the surfactant surrounds the carbon dioxide gas, and the hydrophobic active component is attached to the hydrophobic end of the surfactant. |
