Description
Technical field
The present invention relates to a kind of natural drug composition, relate more specifically to a kind of natural drug composition being comprised of Rhizoma Coptidis Fructus Piperis Longi water boiling concentration extract, berberine, Fructus Piperis Longi ethanol extraction and piperine, the preparation method of this natural drug composition and this natural drug composition are in the purposes for the preparation of reducing in cancer chemotherapy induced diarrhea medicine.
Background technology
Malignant tumor is current harm humans existence, one of healthy principal disease, and its treatment means comprises operation, chemotherapy, radiotherapy, Chinese medicine, and the effect of chemotherapeutic treatment tumor is particularly outstanding.Chemotherapeutic is cell toxicant antitumor drug, alone or combine with the toxicity such as all can cause that patient suffers from diarrhoea, and after chemotherapy of tumors, diarrhoea is again Chemotherapy-induced Diarrhea.In recent years along with chemotherapeutics emerging and applying as 5-fluorouracil, taxanes, hydroxy camptothecin, irinotecan, xeloda etc., the incidence rate of Chemotherapy-induced Diarrhea improves year by year, if do not carry out active treatment, easily cause patient's dehydration, malnutrition, serum electrolyte disorder, acid base imbalance etc., it is unfavorable greatly not only the rehabilitation of body to be brought, also to CC, bring certain difficulty, therefore effective treatment of Chemotherapy-induced Diarrhea has been become the important component part of tumor patient wholistic therapy.
Chemotherapy-induced Diarrhea is with regard to its clinical manifestation, surely belongs to the Chinese medicine category of " having loose bowels ", and Chinese medicine, for the research of having loose bowels, attracts people's attention, but there is no at present the Chinese patent medicine that antagonism cancer chemotherapy has alleviating diarrhoea effect.Therefore, research and develop a kind of high-efficiency low-toxicity, cheap, the natural Chinese medicine that can be used for of being easy to promote alleviates cancer chemotherapy induced diarrhea becomes clinical problem demanding prompt solution.
Rhizoma Coptidis is the dry rhizome of ranunculaceae plant Rhizoma Coptidis Coptis chinensis Franch., Coptis deltoidea C.Y.Cheng et Hsiao Coptis deltoidea C. Y. Cheng et Hsiao or Coptis Teeta Wall Coptis teeta Wall., and hardship is cold.GUIXIN, spleen, stomach, liver, gallbladder, large intestine channel, the disease such as, dysentery damp and hot for the intestines and stomach.Fructus Piperis Longi is the green fruit of Piperaceae plant Piper longumI., warming spleen and stomach for dispelling cold, therapeutic method to keep the adverse QI flowing downwards pain relieving.Cure mainly: for coldness and pain in the epigastrium, the disease such as vomit, have loose bowels, in recent years, Rhizoma Coptidis and Fructus Piperis Longi antitumaous effect are confirmed, especially berberine and piperine, the inventor, through research and the experiment of each a large amount of formula proportion, has finally obtained optimal drug ratio compositions of the present invention, is the compositions of novelty, and proved that it has fabulous curative effect to cancer chemotherapy induced diarrhea, has completed the present invention thus.
