Abstract:
PURPOSE: A process of preparing a gel type composition containing a specified amount of a biocompatible polymer is provided. Whereby, the composition can be used as a local drug delivery system and formulations thereof and release drug from a local portion for 6 days. CONSTITUTION: This gel type composition comprises a phospholipid-based compound, drug and water, wherein the composition additionally contains 3% by weight of one or more biocompatible polymers selected from the group consisting of hyaluronic acid, chitosan and alginic acid. The phospholipid-based compound is one or more selected from a saturated or unsaturated C6-22 phosphatidylcholine-based compound, phosphatidylethanolamine-based compound, phosphatidylserine-based compound and phosphatidic acid-based compound.
Abstract:
PURPOSE: A new oil-in-water type emulsion formulation using an oil phase contrast agent and a cationic polymer allowing effective delivery of a physiologically active substance such as a gene or a drug into cells is provided together with a method for production thereof. The gene or drug delivery formulation for topical application exhibits high transfection efficiency in desired targeted cells for a long period of time in the case of local gene delivery. CONSTITUTION: The complex formulation for effective delivery of a physiologically active substance such as a gene or a drug into targeted cells comprises 10 to 50% by weight of a cationic polymer and 50 to 90% by weight of iodized oils. The binding ratio of the physiologically active substance and cationic polymer is 1:1 to 1:2. The cationic polymer is selected from the group consisting of polylysine, dendrimer, linear polyethyleneimine, branched polyethyleneimine, chitosan, diethylaminoethyl-dextran, polydimethyl and aminoethylmethacrylate and the iodized oils are selected from the group consisting of iodized poppy seed oil, ethiodol and iodized soybean oil.
Abstract:
PURPOSE: Provided is a p-glycoprotein inhibitor which comprises otilonium bromide as an effective ingredient, thereby increasing the absorption of otilonium bromide into the cell and bioavailability of the drug in the living body. CONSTITUTION: A p-glycoprotein inhibitor is characterized by comprising, as an effective ingredient, otilonium bromide that inhibits the activity of p-glycoprotein and increases the absorption of drugs into the cell. The composition is formulated into a sustained release preparation and releases drugs continuously for 12 hours.
Abstract:
PURPOSE: A process of preparing a paclitaxel oily composition for chemoembolization by adding paclitaxel to an oily contrast medium and then agitating is provided. The composition is easy to manufacture and sterilize and more physiochemically stable than conventional adriamycin/lipiodol preparation. CONSTITUTION: The paclitaxel oily composition is prepared by mixing 0.0001 to 10mg paclitaxel with 1ml oily contrast medium under sterilization conditions, agitating at room temperature and then sterilized by gamma ray. The oily contrast medium is iodized oil having an iodine content of 30 to 50% selected from iodized poppy seed oil, ethiodol and iodized soybean oil. The composition optionally contains 0.1 to 1ml animal oil such as squalane, vegetable oil such as soybean oil or a mixture thereof, based on 1ml oily contrast medium.
