PHARMACEUTICAL COMPOSITIONS HAVING CARBOXYVINYL POLYMER AND POVIDONE POLYMER

摘要

The present invention is directed to pharmaceutical compositions, such as ophthalmic gels. The compositions typically include a carboxyvinyl polymer. A povidone polymer is also typically included to stabilize the carboxyvinyl polymer against agents or ingredients (e.g., therapeutic agent) that can otherwise cause instability to the carboxyvinyl polymer.
