Embodiment 1
[0027] Embodiment 1 drug efficacy experiment
[0028] Experimental results of MDR1-MDCKⅡ cell model:
[0029] UPLC-MS / MS was used to determine the concentration of paclitaxel with a concentration of 1 μM transported to the AP surface through MDRI-MDCKII monolayer cells under the action of different concentrations of traditional Chinese medicine monomers. BL-AP Transport Apparent Permeability Coefficient P app See Table 1 for the values. The experimental results show that various traditional Chinese medicine monomers can inhibit the efflux of paclitaxel to a certain extent.

[0038] The preparation of embodiment 2 capsules
[0039] Ratio of each API:
[0040] Paclitaxel 10g Glycyrrhizic Acid 10g

Abstract
This application is the divisional application of an inventive patent application with the application number of 201110004638.9, the application date of January 11th, 2011 and the name of compound medicine composition for improving oral bioavailability of paclitaxel and the application of the compound medicine composition. The invention discloses a compound medicine composition for improving oral bioavailability of paclitaxel and the application of the composition. The invention further discloses a medicine composition comprising the compound medicine composition and paclitaxel monomer compounds. The compound medicine composition provided by the invention can be used for improving the oral bioavailability of the paclitaxel; and when being used for preparing anti-cancer drugs, the compound medicine composition can improve the anti-cancer effect of the paclitaxel. In the compound medicine composition provided by the invention, the paclitaxel is the main anti-cancer ingredient; the monomer compounds are extracted by traditional Chinese medicine; the oral bioavailability and anti-cancer effect of the paclitaxel are improved by inhibiting the first pass effect of the paclitaxel. Experimental investigation shows that the compound medicine composition provided by the invention is prepared into oral medicines so as to improve blood concentration and anti-cancer effect of the paclitaxel after oral administration.
Description
technical field [0001] This application is a divisional application for an invention patent application with the application number 201110004638.9, the application date is January 11, 2011, and the title is "a compound pharmaceutical composition for improving the oral bioavailability of paclitaxel and its application". The invention relates to the field of pharmaceutical compositions, in particular to a compound pharmaceutical composition for improving the oral bioavailability of paclitaxel and its application. Background technique [0002] Paclitaxel, as a chemotherapy and anticancer drug with a special mechanism, is clinically used to treat a variety of malignant tumors, such as ovarian cancer, cervical cancer, breast cancer, laryngeal cancer, and esophageal cancer. Currently, paclitaxel preparations used clinically are injections. Due to the low solubility of paclitaxel in water, most of the injections currently used use polyoxyethylene castor oil / absolute ethanol (1:1, v...
