| 20110245347 | METHOD FOR SELECTIVELY CRYSTALLIZING A Z ISOMER OF IOPROMIDE - The present invention relates to a method for selectively crystallizing Z isomer of iopromide of formula (I) comprising a) dissolving a crude iopromide comprising a mixture of E and Z isomers or a concentrate thereof in an alcohol, and b) heating the resulting alcohol solution to obtain crystalline of Z isomer of iopromide; and a method for preparing a composition comprising the crystalline Z isomer of iopromide. | 10-06-2011 |
| 20110098791 | PROBE FOR LOCAL ANAESTHETIC SYSTEM - The present invention relates to a probe for a local anaesthetic system, and more particularly, to a probe for a local anaesthetic system which cools a local area of the body to perform a local anaesthetic operation without difficulty. The present invention provides a probe for a local anaesthetic system which cools a local area to be anaesthetized, the probe comprising a cooling pad which has a heat conductive material and a predetermined contacting surface to contact an anaesthetic area; a heat capacity adding means which is liquid to increase a heat capacity of the cooling pad; and a thermoelement which is provided to emit a cool air to at least one of the heat capacity adding means and the cooling pad. The probe performs an anaesthetic operation without pain by instantly cooling a skin layer and blocking a transmission of a pain to the nerve, and performs an anaesthetic operation repeatedly and stably by raising a heat capacity of a cooling pad with a heat capacity adding means. | 04-28-2011 |
| 20100197685 | NOVEL BENZOFURAN TYPE DERIVATIVES, A COMPOSITION COMPRISING THE SAME FOR TREATING OR PREVENTING COGNITIVE DYSFUNCTION AND THE USE THEREOF - The present invention relates to the novel benzofuran derivatives, the preparation thereof and the composition comprising the same. The benzofuran derivatives of the present invention showed potent inhibiting activity of beta-amyloid aggregation and cell cytotoxicity resulting in stimulating the proliferation of neuronal cells as well as recovering activity of memory learning injury caused by neuronal cell injury using transformed animal model with beta-amyloid precursor gene, therefore the compounds can be useful in treating or preventing cognitive function disorder. | 08-05-2010 |
| 20100063285 | ANTIFUNGAL TRIAZOLE DERIVATIVES, METHOD FOR THE PREPARATION THEREOF AND PHARMACEUTICAL COMPOSITION CONTAINING SAME - The present invention relates to triazole derivaties, a method for the preparation thereof, and a pharmaceutical composition containing the same as an active ingredient. The inventive triazole derivaties have an excellent antifungal activity against various pathogens. | 03-11-2010 |
| 20090269414 | PROCESS OF PREPARING MICROSPHERES FOR SUSTAINED RELEASE HAVING IMPROVED DISPERSIBILITY AND SYRINGEABILITY - Disclosed is a process of preparing sustained release microspheres, containing a biodegradable polymer as a carrier and a drug, using spray drying. The process comprises preparing a solution, suspension or emulsion containing a biodegradable polymer, a drug and a solvent; spray drying the solution, suspension or emulsion; and suspending spray-dried microspheres in an aqueous solution containing polyvinyl alcohol to remove the residual solvent and increase the hydrophilicity of the microsphere surface. The process enables the preparation of microspheres having high drug encapsulation efficiency, almost not having a toxicity problem due to the residual solvent, and having good syringeability. The microspheres prepared according to the present invention release an effective concentration of a drug in a sustained manner for a predetermined period when administered to the body, and are thus useful in the treatment of diseases. | 10-29-2009 |
| 20090209540 | Novel Biaryl Benzolmidazole Derivatives and Pharmaceutical Composition Comprising The Same - Disclosed are biaryl benzoimidazole derivatives. They have an inhibitory effect on calcium influx in HEK cells, thereby showing a powerful antagonistic effect on a vanilloid receptor, and further have an analgesic effect, thereby being useful for preventing or treating pain, acute pain, chronic pain, neuropathic pain, postoperative pain, migraine, arthralgia, neuropathies, nerve injury, diabetic neuropathy, neurological illness, neurodermatitis, stroke, bladder hypersensitivity, irritable bowel syndrome, a respiratory disorder such as cough, asthma, and chronic obstructive pulmonary disease, burning, psoriasis, itching, vomiting, irritation of the skin, eyes, and mucous membranes, gastric-duodenal ulcers, inflammatory intestinal diseases, and inflammatory diseases. | 08-20-2009 |
| 20090018339 | Process For Preparing Crystalline Form A Of Lansoprazole - The present invention relates to a process for preparing Crystalline Form A of Lansoprazole. Specifically, the present invention relates to a process for preparing highly pure Crystalline Form A of Lansoprazole in a large scale without any additional conversion step, even by using ethanol in which Crystalline Form B is easily formed. | 01-15-2009 |
