20110077291 | Preparations of Taxanes for Intravenous Administration and the Preparation Method Thereof - The present invention relates to the field of medical technology. More specifically, the present invention relates to a preparation of taxanes for intravenous administration, which consists of two parts: a drug solution and an emulsion. Said drug solution consists of paclitaxel or docetaxel, a pH regulator and a solvent for injection, wherein said solvent for injection is an organic solvent. Said emulsion includes a fat emulsion and is composed of oil for injection, an emulsifier, an antioxidant, an isotonic regulator, a stabilizer, a pH regulator and water for injection. When used, the drug solution at the clinical dosage can be added and mixed homogeneously in the emulsion to perform intravenous drip directly; or the drug solution at the clinical dosage can also be firstly added into the emulsion with no less than 5 times volume of the drug solution and then a predetermined amount of normal saline or glucose solution for injection is added to perform intravenous drip. The preparation of the present invention does not contain solubilizer and has advantages of little toxicity, safety, effectiveness, stability and economy. The fat emulsion is also used as a nutritional replenishment, thus achieving a better therapeutic effect. In addition, the normal saline or glucose solution for injection can be used to replace a considerable amount of the emulsion, which makes the preparation, therefore, not only cost-efficient, but also convenient for transportation and storage in practice. | 03-31-2011 |
