Abstract (en)
[origin: WO2005055987A1] The present invention discloses pharmaceutical compositions comprising of pH sensitive polymers used for taste masking highly bitter drugs. The pH sensitive polymer acts as a reverse enteric coating, which is soluble in the acidic pH range 1.0 to 3.0 normally found in the stomach but is insoluble in the pH range 3.5 to 7 thus inhibiting the release of the bitter drug at the pH of saliva and also at the pH of reconstitution medium in case of liquid orals.
