    • An encased-pellet tablet for an active pharmaceutical ingredient comprises an excipient layer on the outside and an inner core that is surrounded by the excipient layer. The inner core contains a plurality of coated pellets, and the coated pellets comprise pellets of the active pharmaceutical ingredient coated with a pellet coating. The excipient layer contains from about 1 wt. % to about 20 wt. % of at least one cushioning agent selected from polyhydroxyl compounds. A method for manufacturing the encased-pellet tablets involves compressing an excipient material to form a first layer; compressing a plurality of coated pellets containing an API on said first layer to form an inner core thereon and compressing additional excipient material around an exposed portion of said inner core thereby surrounding said inner core with excipient material.
