An intubation device is provided for use with a guide apparatus having a track that is adapted to be associated with an endoscope such that bending of the track is substantially decoupled from bending of the endoscope. The intubation device includes an elongated, flexible tube and a mating member attached to the tube and adapted to slidingly engage the track external of the endoscope. The intubation device further includes a tissue bolster disposed on the proximal portion of the tube and changeable between a collapsed and an expanded configuration. The tube is positionable inside the upper gastrointestinal tract of a patient such that the proximal end of the tube is externalized through the gastric and abdominal walls of the patient, and wherein the tissue bolster is securable against the inner gastric wall when the tissue bolster is in the expanded configuration.

Dosage forms for delayed and pulsed release of therapeutic agents into the stomach are described. The dosage forms are gastric retentive dosage forms that achieve release of the therapeutic agent into the stomach and upper gastrointestinal tract subsequent to administration of the dosage form. The dosage forms find particular use in administration of acid-labile active agents such as proton pump inhibitors, and in treating gastric acid secretion such as gastro-esophageal reflux disease (GERD) and nocturnal acid breakthrough (NAB).

Bioadhesive macrosphere delivery systems (“BDDS”) having prolonged gastric retention time due to bioadhesion rather than physical density or size are described. In general, the macrospheres have diameters that are greater than 200 microns, more preferably greater than 500 microns. The bioadhesive macrospheres are released in the stomach where they reside in close proximity to the gastric mucosa for a prolonged period of time. Increased residence of BDDS in the upper GI can lead to increased systemic absorption of drug in the preferred site of systemic absorption, namely the upper GI tract (upper to mid-jejunum). The BDDS may be engineered either as a capsule with drug delivery controlled by a diffusion-limited membrane or degradable shell, or as a solid matrix system with drug delivery controlled by a combination of diffusion and polymer degradation kinetics.

Rosiglitazone is a drug used to treat type 2 diabetes. Methods for the formation of amorphous rosiglitazone and formulations comprising the amorphous rosiglitazone are described. Other formulations include pulsed-release formulations and formulations for retention in the stomach and upper gastrointestinal tract. Controlled-release dosage form include those wherein the maximum plasma concentration of rosiglitazone occurs greater than one hour after administration to a human and / or wherein less than 75 percent by weight of the rosiglitazone is released at 1 hour after immersion in simulated gastric fluid.

Methods of treatment using the dosage forms and methods of making the dosage forms are also described.

The invention provides an injection for treating a peptic ulcers and a preparation method thereof. The powder injection provided by the invention comprises the active ingredients of Ilaprazole sodium and excipient, wherein the ratio of the both in parts by weight is (1:1)-(1:30), and the preferable ratio is (1:10)-(1:18). The preferable prescription of the powder injection provided by the invention comprises 1 part of Ilaprazole sodium, 1-30 parts of excipient, 0-10 parts of antioxidant and / or 0-0.3 part of metal ion complexing agent; and a right amount of inorganic base is added to regulate the pH value to 9.0-12.0. The Ilaprazole sodium freeze-dried powder injection provided by the invention has stable quality, and is suitable for treating peptic ulcer bleeding and stress ulcers and preventing upper gastrointestinal bleeding caused by serious diseases.

Controlled release oral dosage forms are provided for the continuous, sustained administration of a pharmacologically active agent to the upper gastrointestinal tract of a patient in whom the fed mode as been induced. The majority of the agent is delivered, on an extended release basis, to the stomach, duodenum and upper regions of the small intestine, with drug delivery in the lower gastrointestinal tract and colon substantially restricted. The dosage form comprises a matrix of a biocompatible, hydrophilic, erodible polymer with an active agent incorporated therein, wherein the polymer is one that both swells in the presence of water and gradually erodes over a time period of hours, with swelling and erosion commencing upon contact with gastric fluid, and drug release rate primarily controlled by erosion rate.

Described herein are methods of treating a disease by treatment with oral sustained release methotrexate alone or in combination with folates. In some embodiments, these approaches improve the pharmacotherapeutic performance of methotrexate therapy.Described herein are novel pharmaceutical compositions for oral administration. Also described herein are novel pharmaceutical compositions for the controlled, sustained delivery of one or more drugs to the stomach or upper gastrointestinal tract. Further described are novel pharmaceutical compositions with increased gastrointestinal residence time. More particularly, novel pharmaceutical compositions which can simultaneously, float in gastric fluid, adhere to the mucosal surfaces of the gastrointestinal tract, swell to a size which delays passage through the pylorus, are described herein. In some embodiments, the pharmaceutical compositions comprise methotrexate. In some embodiments, the pharmaceutical compositions comprise methotrexate and a folate compound. Also described herein are methods for treating or preventing diseases, by administration of the pharmaceutical compositions described herein.

The present invention provides a gastric retentive gel composition comprising: (a) a hydrophobic or amphiphilic liquid gelled with an organogelator; (b) an active agent; and (c) a hard wax or wax-like additive, for controlled delivery of the active agent to or through the upper gastrointestinal tract, in particular to or through the stomach. The gel composition forms a stable, floating and coherent raft in the gastric environment, and is not directly expelled from the stomach as a result of gastric emptying. The active agent is released from the composition in a controlled manner for absorption or local action.

The present disclosure provides methods of treating inflammation of the upper gastrointestinal tract, especially the esophagus, by administering an oral corticosteroid. In some cases, the methods include treating eosinophilic esophagitis (EoE) by administering an oral corticosteroid in an induction phase and a maintenance phase to improve peak eosinophilic counts and symptoms. In embodiments, the methods include treating EoE by administering the oral corticosteroid at nighttime and / or while the patient is lying down.
