Patent number: 6251432Abstract: Dosage form unit is provided to deliver one or more beneficial agents into a fluid, such as liquid enteral nutritional product. The dosage form unit includes a core containing at least one beneficial agent, preferably a marker dye, which is dispersible in the fluid. The core also contains a compatible binding agent to bind the beneficial agent together. Additional components of the core may include a plasticizer, a standard flow agent, a lubricant, additional tableting aids and at least one hydrophilic agent. A latex coating encases the core.
