羟基喜树碱是植物类抗肿瘤药。临床上常用地塞米松与抗肿瘤药配伍来预防化疗引起的过敏等副反应。关于羟基再柯碱与地塞米松配伍未见报道，本文就此进行实验，以为临床用药提供参考。方法751－GW型分光光度计（上海分析仪器厂）．PHS－gV型酸度计（杭州华光无线电厂），羟基在 Hydroxycamptothecin is a plant antitumor drug. Clinically, dexamethasone is commonly used in combination with anti-tumor drugs to prevent chemotherapy-induced allergies and other side effects. There has been no report on the compatibility of hydroxy re-kodrine and dexamethasone. This article has conducted experiments on this in order to provide reference for clinical drug use.
