  • Patent number: 8791152
    Abstract: The present invention relates to a stable pharmaceutical composition for injection containing docetaxel and a method of preparing the same. More particularly, the present invention relates to a pharmaceutical composition for injection containing docetaxel having better storage stability than conventional medications, which is prepared by dissolving docetaxel, a water-insoluble compound, in distilled water after mixing it with cyclodextrin (CD) and a water-soluble polymer such as hydroxypropyl methylcellulose (HPMC), polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) and lyophilizing the mixture, and a method of preparing the same.

  • Publication number: 20100305202
    Abstract: The present invention relates to a lyophilized pharmaceutical composition for injection having superior storage stability comprising a taxoid, and a method thereof. More specifically, the present invention relates to a lyophilized pharmaceutical composition for injection having improved solubility and stability of dilution compared to the conventional preparations by dissolving a water-insoluble taxoid in distilled water added with a hydrophilic polymer such as hydroxypropylmethyl cellulose (HPMC), polyethylene glycol (PEG) or polyvinylpyrrolidone (PVP) cyclodextrin (CD), and lyophilizing the mixture and a method thereof.

  • Publication number: 20100069632
    Abstract: The present invention relates to salts of a pyrrolopyrimidinone derivative having superior PDE-5 inhibition activity and a process for preparing the same. More particularly, the present invention relates to a crystalline acid addition salt prepared by reacting a pyrrolopyrimidinone derivative with an acid selected from gentisic acid, maleic acid, citric acid, fumaric acid and tartaric acid. With no hygroscopic property and superior long-term storage stability, photostability and thermal stability, the salts of the pyrrolopyrimidinone derivative are appropriate to be prepared into medications and, with superior PDE-5 inhibition activity, are useful for the treatment and prevention of erectile dysfunction, pulmonary arterial hypertension, chronic obstructive pulmonary disease, benign prostatic hypertrophy and lower urinary tract diseases.
