20090022797Stabilized tolterodine tartrate formulations - A pharmaceutical composition contains tolterodine L-tartrate stabilized against degradation with an acid. Acid-stabilized tolterodine L-tartrate may be used to make various types of immediate release and controlled release dosage forms.01-22-2009
20090022807Drug formulations having inert sealed cores - A drug composition comprising a coated bead is used in the manufacture of immediate release and/or controlled release drug compositions. In a specific embodiment, the bead includes an inert core of a water-soluble or water-swellable material, which has been coated with a seal layer formed from a non-polymeric hydrophobic material. The immediate and/or controlled release beads may be used to form tablets or capsules. A method of making the beads by sequential deposition of multiple layers on the inert cores is also described.01-22-2009
20090169616FORMULATION AND METHOD FOR THE RELEASE OF PAROXETINE IN THE LARGE INTESTINE - The present invention provides a delayed and/or controlled release formulation of paroxetine or a pharmaceutically acceptable salt thereof that is formulated to release a substantial portion of the active ingredient (e.g., paroxetine) in the large intestine of an individual in need thereof. In one embodiment, the present invention provides a controlled release paroxetine composition comprising paroxetine or a pharmaceutically acceptable salt thereof, in a controlled release swallow pharmaceutical formulation, that upon administration, releases the paroxetine substantially in the large intestine. For example, the controlled release paroxetine formulation may be formulated to release greater than about 50% of the paroxetine in the large intestine.07-02-2009
20090292016Stable Pharmaceutical Compositions Containing Pravastatin - Stabilized pharmaceutical preparations containing a drug which is sensitive to a low pH environment, such as pravastatin are disclosed in which pravastatin degradations is prevented with a buffering agent. The basic excipient enhances storage stability.11-26-2009
20100209495GRANULATES, PROCESS FOR PREPARING THEM AND PHARMACEUTICAL PRODUCTS CONTAINING THEM - A granulate for use in a pharmaceutical composition and a pharmaceutical composition manufacture using the granulate, where the granule comprises an active pharmaceutical ingredient (API) having a poor water solubility (i.e., less than about 1 mg/mL) which is intimately associated with at least one pharmaceutically acceptable hydrophilic polymer. The granule optionally contains one or more pharmaceutically acceptable excipients, such as disintegrants, wetting agents, diluents, binders, lubricants, glidants, coloring agents and flavoring agents. The invention also relates to a process for preparing the pharmaceutical granulate and pharmaceutical compositions containing the granulate.08-19-2010
20100209500CONTROLLED RELEASE BUDESONIDE MINITABLETS - Embodiments of a controlled release minitablet comprise an extended release core and an optional pH dependent delayed release coating thereon, wherein the extended release core comprises budesonide, a carrier, an extended release polymer, and an acid. The budesonide may be embedded in the extended release polymer to facilitate extended release of the budesonide upon administration.08-19-2010
20100209501CONTROLLED RELEASE BUDESONIDE MINITABLETS - Embodiments of a controlled release minitablet comprise an extended release core and an optional pH dependent delayed release coating thereon, wherein the extended release core comprises budesonide, a carrier, and an extended release polymer. The budesonide may be embedded in the extended release polymer to facilitate extended release of the budesonide upon administration.08-19-2010
