Abstract
A pharmaceutical formulation having a geometric configuration that affects the release characteristics of active agents contained therein and associated methods are provided. In one aspect, a sustained release oral dosage pharmaceutical tablet may include a first layer having a first active agent, where the first layer is disposed between two adjacent controlled release layers, at least one of the adjacent layers including at least one second active agent. The two adjacent layers are arranged such that they cover a portion of the first layer. The two adjacent layers may be separate layers or they may be joined into a single continuous layer, depending on the overall configuration and geometric design of the oral dosage form.
