Abstract

The present disclosure provides programmable osmotic-controlled oral compositions providing delayed release of a therapeutically acceptable amount of a drug. In certain embodiments, the programmable osmotic-controlled compositions of the disclosure provide a lag time that is independent of the presence or absence of food, type of food, pH, gastric emptying, and volume of gastric fluid. The programmable osmotic-controlled oral compositions of the disclosure comprise a multilayer core comprising a drug for controlled release, wherein the core is coated with a semipermeable membrane comprising an orifice and, optionally, an immediate release coating, comprising a drug for immediate release, over the semipermeable membrane. The multilayered core comprises a pull layer containing the drug and a push layer. The pull layer comprises at least two layers: a placebo layer for providing a desired lag time for the drug release; and an active layer containing the drug and providing a delayed controlled release of the drug. The compositions of the disclosure can be programmed to provide a desired and precise lag time, and release drug, after the lag time, at a rhythm, e.g., that matches the human circadian rhythm of a condition's symptoms and/or of the individual being treated in the application of the therapy to optimize therapeutic outcome and minimize side effects.
