Abstract

The invention relates to a Chinese medicinal composition for treating diabetic nephropathy. The Chinese medicinal composition is prepared from the following Chinese medicinal decoction pieces in parts by weight: 15-25 parts of astragalus, 7-13 parts of cherokee rose fruit, 7-13 parts of Szechuan lovage rhizome, 10-20 parts of sunset abelmoschus flower, 2-8 parts of rhubarb, 7-13 parts of kudzuvine root and 10-20 parts of common achyranthes herb. An oral preparation of the traditional Chinese medicine is prepared by the following steps: extracting the astragalus, the Szechuan lovage rhizome, the sunset abelmoschus flower and the kudzuvine root by using ethanol; collecting an extracting solution and concentrating into clear paste of which the relative density is 1.08-1.15; extracting together with the cherokee rose fruit, the rhubarb and the common achyranthes herb by using water; collecting an extracting solution and concentrating to clear paste of which the relative density is 1.08-1.5; mixing the two clear pastes; continually concentrating into thick paste of which the relative density is 1.30-1.40; adding auxiliary materials to obtain a dosage form suitable for clinical application. A prepared Chinese medicinal oral preparation has the advantages of high extraction efficiency of effective components, stable content, good medicinal effect, low dosage and easiness in preparation and formulation.

Description

technical field [0001] The invention relates to traditional Chinese medicines, in particular to a traditional Chinese medicine composition for treating diabetic nephropathy and a preparation method thereof. Background technique [0002] Diabetic nephropathy (DN) is one of the common and serious chronic complications of diabetes, and it is also the main cause of death in diabetic patients. Diabetes lasts for 10-20 years. It is reported that the incidence of DN is about 40-50% in type 1 diabetes and 30-40% in type 2 diabetes. DN is the main microvascular complication of diabetes, mainly referring to diabetic glomerulosclerosis, a glomerular lesion mainly caused by vascular damage. It is mostly asymptomatic in the early stage, and its incidence increases with the prolongation of the course of diabetes. In the early stage of diabetes, the kidney volume increases, the glomerular filtration rate increases, and it is in a state of high filtration. Later, intermittent proteinuria ...
