A pharmaceutical dosage unit suitable for masking the unpleasant taste of orally administered pharmaceutical agents and which facilitates swallowing comprises a plurality of subdosage units disposed within a container. Each subdosage unit is a pellet with an inner core coated with an active pharmaceutical agent, a first layer surrounding the core comprising a biologically inert excipient or filler, and a second layer surrounding the first layer comprising a mixture of a cationic copolymeric acrylate resin and a basic compound. The container of the dosage unit may be orally ingestible in itself, such as an openable gelatin capsule, or may be a frangible packet which must be opened in order to orally administer the subdosage pellets to a patient.
