  • Pharmaceutical composition with increased solubility by using saccharin
    Patent number: 9775828
    Abstract: The present invention provides a pharmaceutical composition including an ionic liquid composed of a triptan compound and saccharin. Since a triptan compound and saccharin form an ionic liquid to increase the solubility of the triptan compound in the present invention, it is possible to expect a rapid and high dissolution of the triptan compound when a pharmaceutical composition is prepared. In addition, large amounts of organic solvents and acidic solvents need not be used in order to dissolve the triptan compound.
