| 20080220061 | System for manufacturing controlled release dosage forms, such as zero-order release profile dosage form manufactured by three-dimensional printing - The present invention includes controlled release dosage forms and methods of designing and manufacturing dosage forms to obtain specific release profiles, for example, zero-order release profiles, escalating release profiles or decreasing release profiles. The dosage forms of the present invention can include spatial variation of API concentration in the dosage form and can include nested regions. Dosage forms according to the present invention may be manufactured by any appropriate method for obtaining the internal structure as disclosed herein for producing zero-order release profiles and increasing or decreasing release profiles. The invention further includes methods of manufacturing such dosage forms, such as by three-dimensional printing, possibly also including compression of the dosage form after three-dimensional printing. The invention further includes methods of designing such dosage forms. Release profiles from non-uniform distributions of API concentration may be predicted based on simple experiments with uniform-concentration dosage forms. | 09-11-2008 |

| 20090169622 | DELAYED-RELEASE ORAL PHARMACEUTICAL COMPOSITION FOR TREATMENT OF COLONIC DISORDERS - A timed or delayed release oral composition delivery system for the treatment of colonic disorders and diseases is provided. According to one aspect, a delayed release oral pharmaceutical composition includes an active core comprising a therapeutically effective amount of 5-amino salicylic acid (i.e., mesalamine); a primary coating composition disposed around the active core, wherein the primary coating composition includes an enteric polymer; and a secondary coating composition disposed around the primary coating composition, wherein the secondary coating composition includes a ratio mixture of ethyl cellulose and hydroxypropyl methylcellulose. | 07-02-2009 |
| 20090280173 | Multilayer Omeprazole Tablets - Multilayer tablets of Omeprazole and/or a salt thereof essentially bioequivalent in terms of plasma Omeprazole C | 11-12-2009 |
| 20100172983 | Pharmaceutical Compositions for the Coordinated Delivery of Naproxen and Esomeprazole - The present disclosure is directed to drug dosage forms that release an agent that raises the pH of a patient's gastrointestinal tract, followed by a non-steroidal anti-inflammatory drug. The dosage form is designed so that the NSAID is not released until the intragastric pH has been raised to a safe level. The disclosure also encompasses methods of treating patients by administering this coordinated release, gastroprotective, antiarthritic/analgesic combination unit dosage form to achieve pain and symptom relief with a reduced risk of developing gastrointestinal damage such as ulcers, erosions and hemorrhages. | 07-08-2010 |
| 20100285125 | DELIVERY SYSTEM FOR POORLY SOLUBLE DRUGS - The present invention relates to an oral drug delivery system for poorly soluble drugs, which can provide sustained near zero order release of poorly water soluble drugs from erodible matrix systems. Erodible matrix core is prepared using at least one active and erosion modulators in a matrix of low molecular weight and high molecular weight hydrophilic polymers in combination with a pH sensitive polymer which enable uniform hydration, controlled erosion and pH independent drug release through out GIT. The core optionally contains solubilizers. The core is optionally coated using combination of low molecular weight water soluble and water insoluble polymers, plasticizer and fillers, which provides for drug release, following a lag time, which also helps to reduce food effects in the stomach. | 11-11-2010 |
| 20110142933 | Controlled Release Dosage Form of Tacrolimus - A controlled release dosage form of tacrolimus, comprising a solid dispersion of tacrolimus, wherein a controlled release base, which is selected from the group consisting of a water-soluble macromolecule, a gum base, and a membrane forming agent and does not form the solid dispersion of tacrolimus, is further contained, is disclosed. The controlled release dosage form of tacrolimus has an excellent controlled release and shows a stable blood concentration. | 06-16-2011 |
| 20140141080 | PHARMACEUTICAL COMPOSITIONS FOR THE COORDINATED DELIVERY OF NSAIDS - The present invention is directed to drug dosage forms that release an agent that raises the pH of a patient's gastrointestinal tract, followed by a non-steroidal anti-inflammatory drug. The dosage form is designed so that the NSAID is not released until the intragastric pH has been raised to a safe level. The invention also encompasses methods of treating patients by administering this coordinated release, gastroprotective, antiarthritic/analgesic combination unit dosage form to achieve pain and symptom relief with a reduced risk of developing gastrointestinal damage such as ulcers, erosions and hemorrhages. | 05-22-2014 |
| 20140212489 | PHARMACEUTICAL COMPOSITIONS FOR THE COORDINATED DELIVERY OF NSAIDS - The present invention is directed to drug dosage forms that release an agent that raises the pH of a patient's gastrointestinal tract, followed by a non-steroidal anti-inflammatory drug. The dosage form is designed so that the NSAID is not released until the intragastric pH has been raised to a safe level. The invention also encompasses methods of treating patients by administering this coordinated release, gastroprotective, antiarthritic/analgesic combination unit dosage form to achieve pain and symptom relief with a reduced risk of developing gastrointestinal damage such as ulcers, erosions and hemorrhages. | 07-31-2014 |
| 20150072005 | ASPIRIN FORMULATION FOR INCREASED EFFICACY - Provided are methods for enhancing the efficacy of aspirin. Also provided are methods for reducing pain or preventing or treating heart attack, stroke or blood clot in a subject in need thereof. The methods entail orally administering to the subject a first composition comprising a first amount of aspirin, and a second composition comprising a second amount of aspirin, wherein the first composition is formulated so as to, upon administration, disintegrate or dissolve intraorally providing rapid release of the aspirin of the first composition in the subject, and wherein the second composition is formulated to be substantially more difficult than the first composition to disintegrate or dissolve intraorally but is ingestible and releasable in the gastrointestinal track of the subject. The method can further include administering to the subject a painkiller or an agent suitable for treating a cardiovascular disease or condition. | 03-12-2015 |
| 20150079169 | CONTROLLED DOSING OF CLOPIDOGREL WITH GASTRIC ACID INHIBITION THERAPIES - The present invention provides for novel formulations of clopidogrel in combination with proton pump inhibitors (PPI) and optionally with NSAIDs, for use as improved antiplatelet therapies in stroke and cardiovascular indications. The invention provides the delivery of clopidogrel in pulses or waves, such that the total dose is phased/spread out over time and, advantageously, combined with omeprazole in a way to minimize the conflicting actions these two drugs may have on each other. In addition, the invention also provides the delivery of clopidogrel and a PPI, and optionally aspirin, in a sequential (orderly) manner that would allow for the delivery and metabolism of clopidogrel first, followed by the PPI, and thereafter optionally aspirin. A particular mode of the invention involves the combination of clopidogrel with coformulated immediate release omeprazole+enteric coated aspirin. | 03-19-2015 |
| 20150125524 | PHARMACEUTICAL COMPOSITIONS FOR THE COORDINATED DELIVERY OF NSAIDS - The present invention is directed to drug dosage forms that release an agent that raises the pH of a patient's gastrointestinal tract, followed by a non-steroidal anti-inflammatory drug. The dosage form is designed so that the NSAID is not released until the intragastric pH has been raised to a safe level. The invention also encompasses methods of treating patients by administering this coordinated release, gastroprotective, antiarthritic/analgesic combination unit dosage form to achieve pain and symptom relief with a reduced risk of developing gastrointestinal damage such as ulcers, erosions and hemorrhages. | 05-07-2015 |
