Abstract

An oral delivery vehicle includes an aspected particle including a pharmaceutically active component and excipients, wherein the vehicle is formulated and/or constructed and arranged to provide controlled delivery of the pharmaceutically active component. The aspected particle possesses one dimension that is about an order of magnitude smaller than the other two dimensions. The vehicle may further contain a lubricious coating to improve mouth-feel. The vehicle may further contain a coating to provide sustained drug delivery to the particle.
