1. A solid pharmaceutical dosage form adapted for direct oral administration, in solid form, to a mammal comprising:
- a plurality of microparticles, each said microparticle having a core including at least one pharmaceutical ingredient and a compound which is sweet in taste and which has a negative heat of solution, said compound which is sweet in taste and which has a negative heat of solution being selected from the group consisting of mannitol, sorbitol, a mixture of an artificial sweetener and menthol, a mixture of a sugar and menthol, and methyl salicylate, said compound being present in said microparticles in an amount of between greater than 0 and about 80% by weight of the resulting microparticle, said core being coated with a coating material, which will retard dissolution of said pharmaceutical ingredient in the mouth, as well as the objectionable taste of said pharmaceutical ingredient, surrounding at least a portion of said core;
said solid dosage form being sized and shaped and having a composition and hardness which are adapted for direct oral administration, said dosage form being disintegratable in the mouth so as to release said microparticles.
