Abstract

The present invention relates to a kind of orally disintegrating cepharanthine tablet, which has the functions of promoting reticuloendothelial system, resisting allergic reaction, etc. and is used in preventing and treating leucopenia caused by radiotherapy and chemotherapy, and its preparation process. The orally disintegrating cepharanthine tablet is prepared with cepharanthine as main material and stuffing, disintegrating agent, corrective, flow assistant, lubricant, adhesive or coating material, effervescent agent and other supplementary material, and through tablet pressing in a tablet press. The orally disintegrating cepharanthine tablet has high friability, fast disintegrating, good taste, low production cost and other advantages.

Description

technical field [0001] The invention relates to an orally disintegrating tablet of stepherin, which has the functions of promoting reticuloendothelial system and antiallergic reaction, and is used for the prevention and treatment of leukopenia caused by radiation or chemotherapy and its preparation process. Background technique [0002] Cepharanthine is a kind of bisbenzylisoquinoline alkaloid, which is extracted from the medicinal plants of the genus Stephaniaceae. Cepharanthine has anti-inflammatory, antibacterial, and immune-regulating functions, etc. effect. In recent years, many scholars believe that it also has the function of stimulating the reticuloendothelial system, activating hematopoietic tissue, and promoting the proliferation of bone marrow tissue. It has been used clinically to treat leukopenia and has received certain results. A low-toxic and effective white blood cell-increasing drug. [0003] At present, the chemical, pharmacological and clinical research...
