A rapidly-releasing and taste-masking pharmaceutical dosage form and a process for preparing such oral dosage form are disclosed.

There is provided a method for preparing an orally disintegrating tablet (ODT) composition comprising microparticles of one or more taste-masked active pharmaceutical ingredients, rapidly-dispersing microgranules, and other optional, pharmaceutically acceptable excipients wherein the ODT disintegrates rapidly with saliva in the buccal cavity forming a smooth, easy-to-swallow suspension. Furthermore, the microparticles (crystals, granules, beads or pellets containing one or more actives) with a taste-masking membrane applied by a modified solvent coacervation process comprising a water-insoluble polymer and at least one gastrosoluble inorganic or organic pore-former, exhibit a pleasant taste when placed in the oral cavity and provide rapid, substantially-complete release of the dose on entry into the stomach.

There is provided a method for preparing an orally disintegrating tablet (ODT) composition comprising microparticles of one or more taste-masked active pharmaceutical ingredient(s), rapidly-dispersing microgranules, and other optional, pharmaceutically acceptable excipients wherein the ODT disintegrates on contact with saliva in the buccal cavity in about 60 seconds forming a smooth, easy-to-swallow suspension. Furthermore, the microparticles (crystals, granules, beads or pellets containing the active) applied with a taste-masking membrane comprising a combination of water-insoluble and gastrosoluble polymers release not less than about 60% of the dose is in the stomach in about 30 minutes, thus maximizing the probability of achieving bioequivalence to the reference IR product having rapid onset of action (short T_max). A process for preparing such compositions for oral administration using conventional fluid-bed equipment and rotary tablet press is also disclosed.

Methods for producing chewable emulsion compositions and compositions produced from such methods are disclosed. The emulsion base may be prepared by contacting an aqueous phase and a nonaqueous phase in the presence of an emulsifier.

The compositions may be sugar-free or sugar-containing. The active agent may be added to the emulsion base at a lower temperature compared to the temperature at which either the aqueous or nonaqueous phase is formed. The compositions may be further coated with taste-masking materials, enteric coating materials, or slow-release materials. The compositions may be formed into compressible tablets, beads, granules, or otherwise generally known dosage forms.
