Administration comprises following steps, the injection containing ranitidine hydrochloride is applied firstly by intravenous injection, the paclitaxel injection is dissolved and diluted by normal saline or 5% glucose and sodium chloride solution, and then the diluted paclitaxel injection is applied by intravenous drop infusion.

Description

technical field [0001] The invention relates to a pharmaceutical composition of paclitaxel and ranitidine hydrochloride, in particular to a combined application package of paclitaxel injection and the injection containing ranitidine hydrochloride, belonging to the technical field of medicine. Background technique [0002] Paclitaxel is a new type of anti-microtubule drug, by promoting tubulin polymerization, inhibiting depolymerization, maintaining tubulin stability, and inhibiting cell mitosis. In vitro experiments have shown that paclitaxel has a significant radiosensitizing effect, which may cause cells to stop in the G2 and M phases that are sensitive to radiotherapy. [0003] Paclitaxel is a mitosis inhibitor or spindle poison (Spindle poison), and its mechanism of action is different from that of commonly used chemotherapeutic drugs. It induces and promotes the assembly of microtubules. Paclitaxel has the function of polymerizing and stabilizing microtubules, causing ...
