Pharmaceutical formulation, for oral administration, has a coating of film-forming polymers free of surfactants and anti-foaming agents

摘要

A pharmaceutical formulation, for oral administration, having a single coating of a mixture of at least two barrier agents without a stabilizer, surfactant or anti-foam agent, is new. The coating is a mixture of film-forming polymers, as a dispersion in water, where one barrier agent floats and the other sinks.
