Abstract:
An oral solid dosage form includes a therapeutically effective amount of an NSAID and a proton pump inhibitor in an amount effective to inhibit or prevent gastrointestinal side effects normally associated with the NSAID. Also disclosed is a method of treating a human patient in need of antiinflammatory, analgesic and/or antipyretic therapy, comprising orally administering to the patient an oral pharmaceutical dosage form which includes a therapeutically effective amount of an NSAID and an amount of a proton pump inhibitor effective to substantially inhibit gastrointestinal side effects of the NSAID. The invention is further related to a method of prophylactically treating a human patient who is on a therapy known to have significant gastrointestinal side effects or is about to begin such a therapy, via concurrent administration of an NSAID and a proton pump inhibitor in a combination (single) oral dosage form.
Abstract:
A flash memory device includes a substrate having a trench, a deep N-type well region in the substrate, a stacked gate structure on the substrate, a first and a second spacer on a sidewall of the stacked gate, wherein the first spacer is connected with the top of the trench, a source region in the substrate under the first spacer, a drain region in the substrate under the second spacer, a P-type well region between the stacked gate and the deep N-type well region, wherein the junction between the two well regions is higher than the bottom of the trench, a doped region along the bottom and the sidewall of the trench, wherein this doped region is connected with the source region and isolates the P-type well region from the contact formed in the trench, the contact being electrically connected to the source region.
Abstract:
A stable pharmaceutical composition of omeprazole for oral administration which consists essentially of: (a) a core of Omeprazole or a pharmaceutically equivalent salt, a filler and an alkaline material selected from the group consisting of lysing and arginine; and (b) a single layer of coating on said core which comprises a layer of an enteric coating agent which is applied from an organic solvent based system.
Abstract:
A manufacturing method of flash memory. A substrate is provided, on which a gate structure is formed. A first spacer is formed on the sidewalls of the gate structure. A source region is formed in the substrate at one side of the gate structure. A first conductive layer and a sacrificial layer are formed on the substrate. The first conductive layer and the sacrificial layer are removed until the gate structure is exposed. A thermal oxidation process is performed to form a mask layer on the first conductive layer and the gate structure. The sacrificial layer remaining on the first conductive layer is removed, and the first conductive layer is etched with a square shape. The mask layer is removed, and a second spacer is formed on the sidewalls of the second conductive layer. A drain region is formed in the substrate at one side of the conductive layer.
Abstract:
A controlled release tablet is disclosed which comprises: (a) a homogeneous compressed core which comprises: (i) a medicament which is very slightly soluble to practically insoluble in water at 25° C.; (ii) a water soluble osmotic compound (iii) one or more osmotic polymers; and (b) a membrane coating which completely covers said core tablet which comprises a mixture of a: (i) a water insoluble pharmaceutically acceptable polymer; and (ii) a pH dependent polymer such as an enteric coating polymer, the weight ratio of the pH dependent polymer to the water insoluble pharmaceutically acceptable polymer being 0.1:1 to 0.75:1. A controlled release tablet which comprises: (a) a medicament (a) a homogeneous compressed core which comprises: (i) a medicament; (ii) a water soluble osmotic compound (iii) one or more osmotic polymers; and (b) a membrane coating which completely covers said core tablet which comprises a mixture of: (i) a water insoluble pharmaceutically acceptable polymer; and (ii) an enteric polymer.
Abstract:
A controlled release dosage form of bupropion hydrochloride which comprises: (a) a first pellet having a core of bupropion hydrochloride and hydroxypropyl methylcellulose at a weight ratio of 10:1 to 30:1 and a coating of a mixture of an acrylic resin which is soluble in acidic media and ethyl cellulose; (b) a second pellet having a core of bupropion hydrochloride and hydroxypropyl methylcellulose at a ratio of 10:1 to 30:1; an inner coating of a mixture of an acrylic resin which is soluble in acidic media and a water insoluble polymer and an outer coating which comprises an enteric coating polymer.
Abstract:
An analgesic controlled release dosage form containing: (a) 40-80 weight percent of an analgesic; (b) 10-30 weight percent of a pharmaceutically acceptable filler; and (c) 10-30 weight percent of a carrier base wherein the carrier base is formed from a high molecular weight hydroxypropyl methylcellulose, a water soluble binder and optionally a water insoluble binder.
