They can mask the bitter taste and odor of drugs, e.g. Oral administration can be used, but patients generally object to the oily feel of emulsions in the mouth. Solid dispersion of one or more drug is prepared by solvent evaporation method, grinding, physical mixing and sugar carriers like dextrose Several approaches like adding flavors and sweeteners, use of lipoproteins for inhibiting bitterness, coating of drug with inert agents, microencapsulation, multiple emulsion, viscosity modifiers, vesicles and liposomes, prodrug formation, salt formation, formation of inclusion and molecular complexes, solid dispersion system and application of ion exchange resins have been tried by the formulators to mask …. The compositions of formulations are shown in Table 1 Taste masking could be carried out by coating the granules containing 52% L-HPC with EC/HPMC (4/2) and a 10% coating level. Multiple emulsions have also been employed as intermediate step in the microencapsulation process and are the systems of increasing interest for the oral delivery of hydrophilic drugs, which are unstable in gastrointestinal tract like ….
