Abstract
The present invention discloses coating compositions with taste masking property, comprising a blend of pH sensitive polymers and optionally a pH independent polymer or a blend of the pH sensitive polymer and pH independent polymer used for taste masking of highly bitter drugs. The pH sensitive polymers used comprise the acid soluble polymers and the enteric polymers. The process for the preparation of taste masked pharmaceutical compositions of the bitter drugs comprising the said coating compositions is disclosed. The concomitant use of the polymers inhibits the release of the bitter drug at the pH of saliva. The said coating compositions deliver substantial amount of the bitter drug immediately with improved palatability.
