titleOfInvention |
Humidity-resistant drug formulations and methods of preparation thereof |
abstract |
The invention relates to a pharmaceutical composition of a humidity-sensitive core comprising an active ingredient or pharmaceutically acceptable salt thereof; a coating over the core, the coating containing a cationic polymer; and an additional coating over the cationic polymer-containing coating, with the additional coating including an acidifying agent. Also, methods for preparing such compositions wherein a cationic polymer containing coating is applied over a humidity-sensitive core that contains the active ingredient or pharmaceutically acceptable salt thereof; and then an additional coating is applied over the cationic polymer containing coating. |
