??OBJECTIVE To systematically evaluate the economics of saxagliptin for treatment of type 2 diabetes mellitus. METHODS PubMed, Embase, Cochrane Library, NHS EED, CNKI, Wanfang and CBM were systematically searched. Literatures were screened according to pre-defined inclusion criteria. The quality of included studies were evaluated by CHEERS statement and the economic RESULTS were systematically analyzed. RESULTS Eight cost-effectiveness analyses were included, one of which was conducted in China. Patients among the studies all had blood glucose non-adeguately controlled by monotherapy. When added on to metformin, saxagliptin was cost-effective compared with sulfonylureas (glipizide and glimepiride) and thiazolidinediones (pioglitazone and rosiglitazone). When added on to metformin or sulfonylureas, saxagliptin was cost-effective compared with NPH insulin. CONCLUSION Saxagliptin represents a cost-effective option in treatment of type 2 diabetes mellitus patients with non-adequately controlled blood glucose after monotherapy.  相似文献

??OBJECTIVE To analyze the connotation and composition of the clinical value of drugs, and to build the index system for the evaluation of drug's clinical value, hence to provide references for its scientific evaluation. METHODS We designed the preliminary constructs index system referencingmedicine clinical evaluation indicatorsof German and French firstly. And then the expert interview and Delphi survey were used to analysis to determine the index system and index weight of medicine clinical evaluation. RESULTS The classified index system of the clinical value was established, which was composed of 2 first-grade indexes including clinical value and innovation value and 15 grade two indexes. Experts were invited to assess the value ranking according to the background information of rosuvastatin, atorvastatin and simvastatin statin drugs by their generic names. The expert's scoring results were summarized to determine the sequence. And it were compared with the average market prices in Germany, France, Britain, the United States, South Korea, Japan and analyzed. CONCLUSION The clinical value of drugs is an international standard for determining the reasonable price of drugs. This research method is feasible to determine the drug prices sequencing by the classified clinical value of drugs in the same kind of product. The price sequencing of some generic names of statin drugs did not correspond with its clinical value sequence, and the price can not reflect its value. The integrity and authenticity of the background data directly determine the classification of the clinical value. Various parties are needed to participate in providing detailed data and information.  相似文献

??OBJECTIVE Blood tends to deposit in atrium to form thrombus in patients with atrial fibrillation. Patients with diabetes are in high coagulation state, for whom thrombosis is easy to occur. The number of diabetic patients with atrial fibrillation is large. Warfarin is one of the most widely used oral anticoagulants, which can cause major or fatal bleeding, so it is necessary to perform regular monitoring of international normalized ratio (INR) on all patients treated with warfarin. New kinds of antidiabetic drugs are widely used in clinic, among which a lot affect INR levels achieved with warfarin therapy. Clinical pharmacists should pay attention to drug interactions and monitor adverse drug reactions. As a new antidiabetic drug, exenatide has less reports of interaction with warfarin. The characteristic of the interaction between exenatide and warfarin was investigated, with the aim to optimize the rational and individualized medication. METHODS A case was introduced in which exenatide was administrated combined with warfarin, so that the possible mechanism of exenatide affecting to warfarin were analyzed. RESULTS INR declined from 2.13 to 1.57 after exenatide being added, and decreased further to 1.43 with concurrency of the increasing exenatide dose. On the contrary, INR was on rise as result of discontinuing exenatide. At last, INR returned to 1.78 when the patient discharged. CONCLUSION Exenatide inhibited the absorption of warfarin, which lead to INR decline attributed to its effect of slowing down the gastric emptying. When exenatide and warfarin are combined,the dose of warfarin must be adjusted based on INR under clinical monitoring.  相似文献

??OBJECTIVE To study and collate the literature on rare diseases in domestic and abroad, and comparative analysis, provide a scientific basis for the domestic rare diseases research. METHODS Retrieved the Web of Science, China National Knowledge Infrastructure from January 2011 to June 2016 published literature about rare diseases. RESULTS Through the screening of literature, finally determine the 200 articles for analysis. It is divided into seven research directions:rare diseases policy research, rare diseases legal and regulatory research, rare diseases medical social security study, orphan drugs availability research, orphan drugs economic evaluation study, orphan drug development research, rare diseases defined standard research. CONCLUSION Rare diseases policy research is the focus of research both domestic and abroad. Compared with foreign countries, the domestic research on the availability and economic evaluation of orphan drug is less, especially the economic evaluation research is almost blank. It is suggested that the researchers study the multiple aspects of rare diseases and drugs, and to provide the basis and reference for build rare disease policy in China.In addition to the field of rare diseases research, rare diseases drugs face many difficulties in pharmaceutical research, production and supply.The precondition to solve these problems is the nation formulate specific policies and regulations for rare diseases,and then clear the official definition standards of rare diseases,establish relevant policies to encourage pharmaceutical companies to develop rare diseases drugs.  相似文献

??OBJECTIVE To determine the effects of saxagliptin and exenatide on humerus cancellous bone of diabetes-induced osteopenia rats by histomorphometry. METHODS Thirty-five Cases of female SD rats were randomly divided into normal group (N group, n=7), control group (C group, n=7), and the remaining rats were used to establish the type 2 diabetic model by combination of high-fat&sugar-diet feeding for 4 weeks and then low-dose streptozotocin injection(STZ, 30 mg??kg-1) . After 10 d, the oral glucose tolerance test and the fasting blood glucose were measured, rats with high OGTT(2 h) above 11.1 mmol??L-1 and high FBG above 16.7 mmol??L-1 were divided into model group (M group, n=5), saxagliptin group (G group, n=5) and exenatide group (D group, n=6), and continuously treated for 30 d. The left humerus (proximal humeru metaphometry, PHM) were fixed with 4% paraformaldehyde for 48 h, uncalcified embedded in methyl methacrylate after dehydrated and cleared, and sections were taken for bone histomorphometry after Masson-Goldner Trichrome stained. RESULTS In PHM, there was no statistical significance between N and C group, the trabecular bone area ratio( BV/TV) and trabecular quantity were significantly decreased (P??0.01) in M group, while the trabecular separation degree was increased, comparing with those in C group (P??0.01), and the trabecular bone area ratio( BV/TV) and trabecular quantity in G and D group were higher (P??0.01) than those of model rats, while the trabecular separation degree was decreased, comparing with those in M group (P??0.01). Cell parameters showed no statistical significance between N and C group, the osteocllast number and percentage of osteocllast surface perimeter were significantly reduced(P??0.05, P??0.01) in M group, while the osteoclast number and percent osteocllast surface perimeter were significantly increased (P??0.01) as compared with those in C group, saxagliptin and exenatide were found to significantly induce osteocllast number (P??0.01) and percentage of osteoblast surface perimeter (G group P??0.05, D group P??0.01), while reduce osteoclast number (P??0.01) and percent osteoblast surface perimeter (P??0.05) compared with M group. In growth-plate, there was no statistical significance between N and C group, the thickness of growth-plate and the diameter of the mast cells were reduced in M groups (P??0.01), while the thickness of growth-plate (P??0.01) and the diameter of the mast cells (P??0.05) were increased in G and D group,compared with M group. CONCLUSION Therapeutic effects of saxagliptin and exenatide on diabetes -induced osteopenia rats was showed, and the mechanism may be related to the improved growth rate of growth-plate and the changed bone turnover status.  相似文献

??OBJECTIVE To determine simultaneously the contents of xanthotoxin,bergaptol, and bergapten in cultivated Changium smyrnioides Wollf and its in vitro cultures by HPLC.METHODS Agilent-C18 column (4.6 mm??250 mm,5 ??m) was used for chromatographic separation and PAD was applied as detector. The flow rate was 1.0 mL??min-1with a mobile phase of methanol-water in gradient elution mode. The detection wavelength was set at 314 nm while the injection volume was 10 ??L.RESULTS The linear regression equations of xanthotoxin, bergaptol, and bergapten were Y=17 057??-87.689 (r=1.000 0), Y=23 828??-380.44 (r=0.999 9) and Y=37 123??-441.16(r=0.999 9), respectively. The contents of xanthotoxin and bergapten in cultivated and regenerated specimens were obviously higher than those in calli and suspension cells, while bergaptol was only detected in the latter two samples. A larger amount of furanocoumarins accumulated in the cells from leaves and petioles. CONCLUSION The established method is simple and effective with high sensitivity and good repeatability. It can be adopted in studies on the utilization of Changium smyrnioides, especially the regulation and induction of furanocoumarins.  相似文献
