Abstract
The present invention provides solid pharmaceutical compositions for improved delivery of a wide variety of active ingredients contained therein or separately administered. In one embodiment, the solid pharmaceutical composition includes a solid carrier, the solid carrier including a substrate and an encapsulation coat on the substrate. The encapsulation coat can include different combinations of active ingredients, hydrophilic surfactant, lipophilic surfactants and triglycerides, and solubilizers. In another embodiment, the solid pharmaceutical composition includes a solid carrier, the solid carrier being formed of different combinations of active ingredients, hydrophilic surfactants, lipophilic surfactants and triglycerides, and solubilizers. The compositions of the present invention can be used for improved delivery of active ingredients.
