  • Publication number: 20090022786
    Abstract: The present invention provides an coated oral pharmaceutical dosage form comprising a composition of a non-steroidal anti-inflammatory drug (NSAID) as multilayered spherical granule combined with a composition of prostaglandin, and a film coating. The present invention also provides a method for manufacturing the dosage form, which comprising the steps of preparing the compositions of NSAID and prostaglandin separately, combing the compositions to form a pharmaceutical dosage form, and coating the dosage form with a film coating.

  • Patent number: 7361683
    Abstract: The present invention provides an injectable pharmaceutical composition containing, as an active ingredient, paclitaxel, an anti-cancer agent. The injectable pharmaceutical composition comprises an effective amount of paclitaxel, which is dissolved in polyoxyethylated castor oil, alcohol, and an injectable aqueous solution. A sufficient amount of CO2 is added to stabilize paclitaxel in the injectable pharmaceutical composition to make the injectable pharmaceutical composition to a pH about 5.0.

  • Publication number: 20070148240
    Abstract: The present invention provides oral pharmaceutical formulation for azole antimicrobial drugs such as itraconazole, saperconazole, ketoconazole, and fluconazole. The oral pharmaceutical formulation contains a core and a drug coating layer. The drug coating layer contains the azole antimicrobial drug and a binder, but not containing an emulsion (such as polyoxypropylene-polyoxyethylene block copolymers, polyoxyethylene-sorbitan-fatty acid esters, sodium lauryl sulfate, or vitamin E polyethylene glycol succinate) and/or an absorbent aid (such as DL-malic acid, citric acid, ascorbic acid, and alginic acid). The oral pharmaceutical formulation can optionally contain a protective layer, such as polyethylene glycol 20,000. The present invention also provides a method for preparing and using the formulation.

  • Patent number: 7166641
    Abstract: The present invention provides pharmaceutically acceptable salts having local anesthetic and anti-inflammatory activities. The preferred pharmaceutically acceptable salt is a diclofenac salt of lidocaine. Diclofenac is a non-steroidal anti-inflammatory drug (“NSAID”). Lidocaine is a local anesthetic. Other NSAID (except the salicylic acid derivatives of NSAID) can be used to replace diclofenac and/or other local anesthetics can be used to replace lidocaine. The pharmaceutically acceptable salts are crystalline compounds, which are distinctively different from either the NSAID alone or the local anesthetic alone, as indicated by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), High Performance Liquid Chromatography (HPLC) and Fourier-Transformed Infrared Spectroscopy (FTIR) analyses.

  • Patent number: 7132452
    Abstract: The present invention provides a topical formulation containing NSAID, particularly diclofenac. The topical formulation is particularly useful for alleviating pain/inflammation associated with infection caused by herpes virus, especially herpes simplex virus (HSV) and varicella-zoster virus (VZV). Similar relief can be achieved where diclofenac is replaced with another non-steroidal anti-inflammatory drug (NSAID), which includes, without limitation, etodolac, ketorolac, bromfenac, diflunisal, ibuprofen, fenoprofen, ketoprofen, naproxen, suprofen, meclofenamate, mefenamic acid, piroxicam, meloxicam, indomethacin, sulindac, phenylbutazone, oxyphenbutazone, and tolmetin. The topical formulation is further characterized by its fast relief on pain and/or inflammation associated with infection caused by herpes virus, i.e., a complete relief in no more than seven (7) days after the application of the topical formulation on skins of patients.

  • Publication number: 20030191187
    Abstract: The present invention provides a stable pharmaceutical composition which contains an acetic acid class of non-steroidal anti-inflammatory drug (NSAID), a phosphate solution, an isotonic agent, and water. The pharmaceutical composition is particularly suitable for parenteral injection such as intravenous or intramuscular injection. The preferred NSAID is ketorolac tromethamine, which includes any racemic mixture of [−]S and [+]R ketorolac tromethamine. The preferred phosphate solution contains sodium phosphate monobasic (NaH2PO4) or potassium phosphate monobasic (KH2PO4), with or without crystalline water. The preferred isotonic agent is NaCl. The pharmaceutical composition is preferably at pH 6.0 to 8.5 and with osmolarity within 0.5 to 3.
