摘要：
The present invention relates to an amorphous solid dispersion comprising a tetrazole derivative of the formula (I) or a pharmaceutically acceptable salt thereof as an active ingredient. The solid dispersion of the present invention comprises a water-soluble polymer or an acid so as to improve the solubility of its active ingredient, i.e., the tetrazole derivative of the formula (I), thereby improving its absorption rate, and thus can be effectively used to reduce multi-drug resistance (MDR) in cancer cells
