Description

A pharmaceutical composition for treating gout and preparation method thereof
Technical Field
The invention belongs to the field of traditional Chinese medicines, and particularly relates to a pharmaceutical composition for treating gout and a preparation method thereof.
Background
Gout (Gout), which is a disease caused by purine metabolism disorder and/or reduced uric acid excretion due to various reasons, is characterized in that sodium urate crystals are formed in joints and other tissues, which can cause repeated attack of acute arthritis, the sodium urate crystals can further form lumps to form tophus, which causes chronic arthritis, joint deformity, even can cause loss of joint function, and the urate can also be produced in kidneys to cause gouty nephropathy. Gout occurs well in men 40-50 years old and postmenopausal women, but the age of onset is gradually advancing toward a lower age. According to epidemiological research, the number of patients suffering from hyperuricemia currently exceeds 1 hundred million in China, and nearly 2000 million patients with gout are diagnosed, and the pain of the patients is increased at a speed of about 10% per year, so that the patients suffering from gout attack become one of the diseases which seriously affect the life and work of people.
At present, the western medicine generally treats gout from the symptoms, and applies anti-inflammatory analgesic drugs, uric acid formation inhibition drugs or uric acid excretion promotion drugs and the like, can only relieve the clinical symptoms of gout to a certain extent, can treat symptoms but not root causes, and needs to take medicines for a long time in order to relieve the symptoms, and the gout rapidly recurs after stopping taking the medicines, so that the treatment effect is limited, and the western medicine can bring serious side effects of the medicines, such as nausea, vomiting, dyspepsia, headache, dizziness and the like to patients.
The traditional Chinese medicine considers that gout belongs to the category of arthralgia in the traditional Chinese medicine, and a chapter in Su Wen Bi Lun indicates that the so-called arthralgia is caused by severe wind, cold and dampness, and the external causes of the arthralgia are wind, cold and dampness which are mixed and become the arthralgia. The victory of wind-qi is arthralgia-syndrome, the victory of cold-qi is arthralgia-syndrome, and the victory of damp-qi is arthralgia-syndrome. The disease name of gout is firstly proposed by Zhu Danxi in the book of Greek treatise, "gout is usually painful, the pain part is red, swollen and scorching or the body is full of heat", and the gout treatment principle of "using pungent-heat agent to disperse cold-dampness, develop the striae and make blood flow through" is proposed. The pathogenesis of gout is supplemented and enriched by the traditional Chinese medical doctors in the later world, and is considered to comprise: deficiency of vital qi at the early stage of gout disease, such as deficiency of innate essence, deficiency of liver and kidney, disharmony between nutrient and defensive qi, deficiency of qi and blood, and obstruction of phlegm-dampness, which results in invasion of exogenous pathogenic factors, obstruction of channels and collaterals, unsmooth circulation of qi and blood, and increase of obstruction of wind-cold-dampness. Liver pertains to wood, kidney pertains to water, and both of them nourish one another and are damaged by one injury. If liver and kidney are deficient, essence and blood are deficient, muscles and bones are not nourished, and liver and kidney qi is weakened, it is easy to catch wind-cold-dampness pathogen. Defensive qi is mainly the functional basis-defensive qi and defense in the category of traditional Chinese medicine, while nutritive blood is mainly the material basis, and both can influence each other and restrain each other; when viewed from the disease position, defensive qi is on the exterior, nutritive blood is in the interior, qi is the commander of blood, blood is the mother of qi, qi is vigorous when blood is vigorous, blood is vigorous when qi is vigorous, blood is circulated when qi circulates, blood stasis is caused by qi stagnation, nutrient-defense imbalance is susceptible to exogenous pathogenic factors, exogenous pathogenic factors invade, and unsmooth circulation of qi and blood and malnutrition of tendons and vessels are easy to cause. Aiming at the treatment of gout, gout powder, gout decoction, Simiao pills, modified Simiao powder, modified Sanmiao pills and the like appear in sequence, and a certain treatment effect is achieved, but not ideal.
