Abstract
The present disclosure provides dosage forms designed to deliver active pharmaceutical ingredients (APIs) in a controlled release manner.

In some cases, the dosage form includes a drug composition including a pharmacologically active agent, a barrier layer covering at least a portion of the drug composition, and a drug layer covering at least a portion of the barrier layer, wherein the drug layer includes the pharmacologically active agent. Related methods of making and administering the disclosed dosage forms are also provided.
