Abstract

An orally-applied dropping pill of anticancer alkaloid contains camptothecine or taxol or harringtonine or homoharringtonine and matrix of dropping pill. Its preparing process includes proportioning,thermal fusion, stirring, and dropping it at 60-150 deg.c in condensing agent at speed of 20-100 drops per min, and removing condensing agent.

Description

technical field [0001] The invention relates to a drop pill of medicine, in particular to an oral drop pill of alkaloid with anticancer effect and a preparation method thereof. Background technique [0002] Malignant tumor is a common and frequently-occurring disease that seriously threatens human health. Current tumor treatment methods include drug therapy, surgery and radiation therapy. Antineoplastic drugs refer to drugs against malignant tumors, also known as anticancer drugs. The alkaloids with anti-cancer effect extracted from plants are an important category of anti-cancer drugs, such as camptothecin extracted from Camptotheca japonica, paclitaxel extracted from the bark of Taxus brevifolia, and The harringtonine and homoharringtonine are extracted from the cloverleaf plant of the family Torreya. These alkaloid active drugs with anti-cancer effects can also be obtained by chemical synthesis technology. They are all extremely poor in water solubility, and currently ...
