{"title":"Health-economic comparison of three recommended drugs for the treatment of osteoporosis.","authors":"J G Brecht,&nbsp;H P Kruse,&nbsp;W Möhrke,&nbsp;A Oestreich,&nbsp;E Huppertz","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Osteoporosis is a large and growing disease with significant health consequences. Based on an evaluation of clinical evidence, the German osteology umbrella organization DVO (Dachverband Osteologie deutschsprachiger wissenschaftlicher Fachgesellschaften) published guidelines in March 2003 for the diagnosis and treatment of osteoporosis. For prevention of fractures in women with postmenopausal and senile osteoporosis, these guidelines recommend three treatment options as first-line therapy: risedronate, alendronate and raloxifene. No evidence is currently available for the reduction of hip fractures by raloxifene. Only risedronate and alendronate, therefore, are recommended for prevention of hip fractures. Information on the cost-effectiveness of preventing and treating osteoporosis may support decision makers in more efficient allocation of resources. Accordingly, the objective of this study is the comparative assessment of the cost-effectiveness of risedronate, alendronate and raloxifene for patient populations in Germany at high risk of osteoporotic fracture due to low bone mineral density (BMD) (i.e., T-score < -2.5) and resulting from a history of at least one previous vertebral fracture, as compared to osteoporotic patients with no treatment. Target variables for the economic comparison are costs per hip fracture avoided and costs per quality-adjusted life year (QALY) gained. Hip fractures are the most costly and best-documented complication of osteoporosis. A cost-effectiveness analysis was therefore conducted, using as criteria for evaluating intervention the incremental cost per hip fracture avoided and the cost per QALY gained. We used a fracture-incidence-based Markov model of osteoporosis, with analysis of patients' transition across outcome states over time (e.g., fracture, healthy, dead). Base-case analysis was conducted on a cohort of 1,000 women aged 70 with low spine BMD and prevalent vertebral fracture, over 3 years of treatment with risedronate, alendronate or raloxifene, and with application of a 10-year analytic time horizon. Model inputs included hip and vertebral fracture incidence rates; relative risk of fracture given low BMD and prevalent vertebral fracture, fracture cost, treatment prices/day (risedronate: 35 mg, 1.76 euro; alendronate: 70 mg, 1.82 euro; raloxifene: 60 mg, 1.82 euro); health utility; and efficacy in terms of relative-risk reduction of fracture of the hip (60% risedronate; 51% alendronate; not significant raloxifene) and vertebrae (49% risedronate; 47% alendronate; 30% raloxifene). A 5% discount rate was applied to cost and outcomes. In the base case, treatment with risedronate reduces costs from the social insurance perspective with respect to both endpoints: i.e., costs per averted hip fracture and QALY. Over the 3-year treatment period and 10-year observation, furthermore, risedronate proved superior to alendronate and raloxifene (i.e., risedronate was less expensive and more effective).

{"title":"Genetic polymorphism of cytochrome P450 enzymes in Asian populations: focus on CYP2D6.","authors":"M Kitada","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Published studies demonstrate that significant ethnic differences can exist in the metabolism of some drugs. These differences are caused by cytochrome P450 polymorphisms and result in the potential for wide interpatient and interethnic variability in adverse events. One of the most common of these cytochrome P450 polymorphisms is related to the CYP2D6 isozyme. Many classes of commonly used drugs are metabolized by CYP2D6, creating the potential for significant adverse events. Due to the variety of genetic polymorphisms among Asian populations, this article focuses on this group rather than on other ethnic populations and discusses the clinical importance of genetic polymorphisms with regard to potential drug interactions. Polymorphism of CYP2D6 can either increase the rate of drug elimination (ultrametabolizers, leading to faster metabolic clearance potentially resulting in reduced effectiveness and need for higher doses) or decrease drug metabolism (poor metabolizers, which may increase the potential for drug interactions and adverse events). Although the CYP2D6 poor metabolizer phenotype is less frequent in Asian than in Western populations (e.g. about 1% in Thai, Chinese and Japanese populations and up to 4.8% in Indians versus 5-10% in Caucasians), the increased prevalence of the CYP2D6*10 allele in Asians does have an impact on drugs metabolized by CYP2D6. Enzyme activity is reduced, potentially increasing circulating drug doses and increasing the risk for drug interactions. Thus, in Asian populations it may be important to optimize pharmacotherapy either by assessing patients' CYP2D6 genotype, or by prescribing medications that are not metabolized by this isozyme.</p>","PeriodicalId":13940,"journal":{"name":"International journal of clinical pharmacology research","volume":"23 1","pages":"31-5"},"PeriodicalIF":0.0,"publicationDate":"2003-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"24079197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
