Abstract
A unique storage stable liquid polymer composition is described containing a water-soluble, low viscosity cellulosic polymer, bleaching agent and vehicle. Also, described are uses of this composition for the bleaching of teeth, treatment of dental plaque, gingivitis, and other oral and periodontal diseases that respond to chemical oxidizing agents.
Claims59
A sustained-release film-forming liquid polymer composition comprising:
- (a) a film-forming amount of a water-soluble cellulosic polymer;
- (b) an efficacious amount of a pharmaceutically acceptable peroxy compound;
- (c) a pharmaceutically acceptable stabilizing additive which is soluble in hydroalcoholic solution, is selected from the group consisting of citric acid, a deferoxamine mesylate, and an edetate salt of an alkaline-earth metal, and is present in an amount sufficient to stabilize said peroxy compound in the presence of said polymer;
- and
- (d) a pharmaceutically acceptable vehicle, wherein said film-forming liquid polymer composition is stable at ambient temperature for at least 30 days.
