Abstract (en)

[origin: WO2006061846A1] The present invention discloses compositions, comprising a lipid-polymer matrix to mask the bitter or unpleasant taste of the medicament. The lipid or a blend of lipids, are used in combination with the pH dependent polymer where the said polymer is acid soluble or swellable. The process for the preparation of taste masked pharmaceutical compositions of the bitter drugs comprising the said lipid-polymer compositions are disclosed. The concomitant use of the acid soluble polymer, which remains collapsed at the pH of saliva, inhibits the release of drug at that pH and hence they further help in bitterness inhibition. The said compositions deliver substantial amount of the bitter drug immediately at the gastric pH with improved palatability.
