TASTE MASKED PHARMACEUTICAL COMPOSITION COMPRISING PH SENSITIVE POLYMER

摘要

The present invention discloses a substantially amorphous pharmaceutical composition comprising a drug that can exist in a variety of polymorphic forms and a pH sensitive polymer, which inhibits the crystallization of the drug during formulation and reconstitution. Polymers of higher molecular weight are more effective at lower loading, especially when the drug polymer matrix is prepared by the solvent evaporation or solvent extraction technique. The composition used as dry syrups maintain bioavailability of the drug and effectively mask the taste of the drug when the composition is reconstituted.
