ABSTRACT:
Controlled release dosage forms for low solubility drugs are disclosed wherein an amorphous solid dispersion of the drug is coated with a non-dissolving and non-eroding coating that controls the influx of water to the core so as to cause extrusion of a portion of the core, as well as a method of treating a disease or disorder comprising administering such dosage form to a person.
