A combination of sheets can be combined into an ingestible unit. The individual sheets can be prepared to have one or more functionalities, such as providing a biologically active agent, disintegrating and opening the unit, controlling release of an agent, facilitating absorption from the GI tract, as well as many others. The individual sheets can be selectively identified for combining into a multifunctional ingestible unit with a random or predetermined arrangement or stacking pattern. The individual sheets can be loose in a capsule or laminated together into a stacked layered structure. The combination of sheets can be pressed, laminated, tableted, or otherwise prepared into an ingestible unit. The ingestible unit can be predetermined to be useful for administering a drug, drug combination, multi-drug regimen as well as tailored to subject-specific multi-drug therapeutic regimens. The sheets can be loaded with any type of agent ranging from drugs to anti-counterfeit agents.
