Embodiment 1

[0016] Weigh 500g of Qingfengteng, 1000g of celandine, and 1000g of Chinese peach leaves. The above three flavors, celandine, and Qingfengteng add 10 times the amount of 85% ethanol to soak for 24 hours, heat and reflux 3 times, each time for 2.5 hours, combine the alcohol extracts, recover the ethanol under reduced pressure and concentrate to 1:1, use 1.5mol / L phosphoric acid to adjust the pH to 2.3, let it stand for 24 hours, filter, adjust the pH of the filtrate to 11 with 60% sodium hydroxide solution, extract 6 times with an equal amount of chloroform, combine the chloroform liquid, recycle the chloroform, and dry the residue in vacuum to obtain total alkaloids. Decoct Chinese peach leaves with water for 3 times, 2 hours each time, combine the decoction liquid, filter, concentrate the filtrate under reduced pressure, and use ethanol precipitation treatment twice. The alcohol content of the first solution reaches 70%, and the second time reaches 80%. %, filter each time,...

Description

Technical field [0001] The invention relates to a medicine for analgesic cancer pain, and also relates to a preparation method of the medicine. Background technique [0002] Cancer pain is a common worldwide problem. Effective analgesic treatment, especially for advanced cancer patients, is one of the four priorities of the World Health Organization's Comprehensive Cancer Programme. According to the statistics of the World Health Organization, there are about 7 million new cancer patients in the world every year, and more than 4.3 million deaths, of which 30 to 50% of the patients are accompanied by different degrees of pain when they die. The mechanism of cancer pain in modern medicine has not been fully clarified. [0003] Currently, cancer pain is still a difficult disease to conquer. The World Health Organization recommends a three-step therapy for the treatment of cancer pain. For mild pain, use non-opioid analgesics, such as: paracetamol, aspirin, ibuprofen, naprox...
