  • 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.

  • Patent number: 6168806
    Abstract: The present invention relates to a fast-release as well as a prolonged release type of nifedipine pellets and the process for the preparation thereof. The fast-release type of nifedipine pellets comprises a particulate core which is covered by a nifedipine coating layer. The particulate core comprises water-soluble or water-insoluble excipient(s) and a pharmacologically acceptable carrier. The nifedipine coating layer comprises an effective amount of nifedipine dissolved in organic solvent(s). This nifedipine coating layer can further be mixed with a suspension which comprises an adhesive, an emulsifier, and a dispersant. The preferred composition of the fast-release type of nifedipine includes 20-70% of the particulate core, 3-15% of nifedipine, 1-20% of emulsifier, 1-20% of adhesive, and 1-30% of dispersant.
