Abstract: Pharmaceutical compositions of topiramate for once-a-day oral administration are provided. The formulations comprise a sustained-release component and an optional immediate-release component, the compositions of which can be selectively adjusted, respectively, to release the active ingredient along a pre-determined release profile. Method of treating or preventing pathological disorders in mammalian subjects comprising the administration of the novel formulations disclosed herein is also provided.

Abstract: Drug formulations having reduced abuse potential which contain one or more of (1) a bittering agent, (2) a bright deterrent/indicator dye and (3) fine insoluble particulate matter. The bittering agent and dye are in a form which does not affect proper administration of the drug, but the bittering agent creates a bitter side effect when the dosage form is crushed or chemically extracted and nasally, orally, buccally or sublingually administered and the dye produces a bright color when crushed and contacted. The fine insoluble particulate matter hinders extraction of the drug from the dosage form and, when crushed, can deter intravenous injection because of the presence of the insoluble particles or hinder injection by blocking an intravenous needle. The bright color of the dye, when extracted, also has a psychologically deterrent effect on intravenous abusers.

Abstract: The current invention offers a method of treatment of aggression in a human subject suffering from ADHD, comprising: (a) determining the weight of the human subject; (b) calculating a dose of molindone such to achieve a plasma concentration, based on body weight, that does not saturate the molindone receptors; (c) administering the dose of step (b) to the mammalian subject.
Abstract: An oral pharmaceutical dosage form with enhanced gastrointestinal permeability, comprising a therapeutic quaternary ammonium compound together with an organic acid.
Abstract: Disclosed are once-daily formulations containing tetracyclines, especially doxycycline. Such formulations are useful, for instance, for the treatment of collagenase destructive enzyme-dependent diseases, such as periodontal disease and acne, and acute and chronic inflammatory disease states, such as rosacea and arthritis.
