摘要: The invention provides controlled release pharmaceutical formulations having a coated core with the core comprising a drug-containing composition and a water-swellable composition, each occupying essentially separate regions within the core. The drug-containing composition comprises a PDE4D inhibitor, or a pharmaceutically acceptable salt thereof, preferably (R)-2-null4-(nullnull2-(benzonull1,3nulldioxol-5-yloxy)-pyridine-3-carbonylnull-aminonull-methyl)-3-fluoro-phenoxynull-propionic acid, or a pharmaceutically acceptable salt thereof, or 2-(4-fluorophenoxy)-N-null4-(1-hydroxy-1-methyl-ethyl)-benzylnull-nicotinamide, or a pharmaceutically acceptable salt thereof, and a drug-entraining agent. The coating around the core is water-permeable, water-insoluble, and has at least one delivery port therethrough. The invention further provides methods of reducing the nausea and emetic effects of PDE4D inhibitors, and controlled-release formulations having improved PDE4D inhibitor in vivo and in vitro profiles.

摘要: 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.
