Disclosed herein are novel compositions and methods for controlling the release of bile acid sequestrant to the stomach in order to treat or prevent upper GI tract disorders or disorders of the throat. The methods generally include administering to a patient in need thereof a therapeutically effective amount of a pharmaceutical composition comprising at least one bile acid sequestrant dispersed in a polymeric matrix. The bile acid sequestrant composition may be administered alone or in combination with at least one proton pump inhibitor, and optionally one or more agents chosen from antacids, histamine H.sub.2-receptor antagonists, y-aminobutyric acid-I3 (GABA-B) agonists, prodrugs of GABA-B agonists, acid pump antagonists, protease inhibitors and GC-C agonists.

Provided are methods and compositions for treating nocturnal symptoms of Parkinson's disease, morning akinesia, or associated symptoms thereof in a human subject in need thereof, wherein circulating plasma levels of levodopa are provided for an extended period of time following a period of delay after administration.

The present invention provides dimethyl fumarate (DMF) particles and methods of preparing the DMF particles. Also provided is DMF coated particles comprising DMF particles coated with an enteric coating. The invention also provides various dosage forms and methods of treating a disease or disorder (e.g., multiple sclerosis).

The present invention provides a delivery system which improves the stability, solubility and permeability of certain types of biologically active compounds in the gut after oral consumption. The delivery system comprises carrier granule comprising an agglomeration of solid lipid particles and a biologically active compound. The biologically active compound may be used with the delivery system to treat illnesses relating to inflammation, oxidation, or protein aggregation where a therapeutic blood and tissue level is required for treating the illness.

The present invention relates to new pharmaceutical compositions comprising benzoquinoline compounds, and methods to inhibit vesicular monoamine transporter 2 (VMAT2) activity in a subject for the treatment of chronic hyperkinetic movement disorders.

The present invention relates to methods for treatment of cardiovascular conditions selected from high blood pressure, heart failure, or heart attack. The present invention further relates to a method of treating cardiovascular conditions comprising orally administering once a day to a human subject in need thereof the compound valsartan in an extended release dosage form, wherein the ratio of mean plasma concentration of valsartan provided by the extended release dosage form to the mean plasma concentration of valsartan provided by an immediate release dosage form of valsartan over 8 hour to 24 hour period after administration is greater than 1 in a single dose human pharmacokinetic study.

Gastric retentive dosage forms for sustained release of acamprosate are described which may allow once- or twice-daily dosing for both acute and long-term treatment of a disorder including alcohol dependence, tinnitus, sleep apnea, Parkinson's disease, levodopa-induced dyskinesias in Parkinson's disease, Alzheimer's disease, Huntington's disease, Amyotrophic lateral sclerosis, Cortical spreading depression, migraine, schizophrenia, anxiety, tardive dyskinesia, spasticity, multiple sclerosis, various types pain, or binge eating. Methods of treatment using the dosage forms and methods of making the dosage forms are also described.

Embodiments of the invention provide swallowable devices, preparations and methods for delivering drugs and other therapeutic agents within the GI tract. Some embodiments provide a swallowable device such as a capsule for delivering drugs into the intestinal wall or other GI lumen. The device comprises a capsule sized to be swallowed and pass through the intestinal tract. The capsule can include at least one guide tube, one or more tissue penetrating members positioned in the guide tube, a delivery member, an actuating mechanism and a release element. The release element degrades upon exposure to various conditions in the intestine so as to release and actuate the actuating mechanism. Embodiments of the invention are particularly useful for the delivery of drugs which are poorly absorbed, tolerated and/or degraded within the GI tract.

GHB drug delivery systems comprising a floating interpenetrating network (IPN) are provided. The pharmaceutical compositions contain at least one IPN forming system, at least GHB drug, and at least one gas generating agent, such that upon oral ingestion of the compositions, a floating IPN is formed in situ. These floating IPN provide extended release of the GHB drug entrapped therein for at least about 3 hours.

Disclosed herein are novel compositions and methods for treating or preventing upper GI tract disorders and protecting stratified squamous epithelium against injury by a noxious substance. The methods generally include administering to a patient in need thereof a therapeutically effective amount of a pharmaceutical composition comprising at least one bile acid sequestrant, alone or in combination with at least one proton pump inhibitor, and optionally one or more agent chosen from antacids, histamine H.sub.2-receptor antagonists, γ-aminobutyricacid-b (GABA-B) agonists, prodrugs of GABA-B agonists, and protease inhibitors.
