Irbesartan and amlodipine in the treatment of patients with microalbuminuria,hypertension and type 2 diabetes in Taiwan: a modelling projection over 25 years |
| |
Abstract: | SummaryThis modelling study aimed to evaluate the long-term cost effectiveness of four treatment strategies: early irbesartan; late irbesartan; amlodipine; and standard hypertensive treatment in patients with diabetes, hypertension and microalbuminuria in Taiwan. A Markov model was used to project costs and clinical outcomes over lifetimes.Early irbesartan (initiated in microalbuminuric patients) yielded the largest improvements in life expectancy (0.78 years) compared with standard treatment. Late irbesartan and amlodipine (started in patients with overt nephropathy) also resulted in slight improvements in life expectancy (0.109 and 0.001 years, respectively). Both early and late irbesartan reduced lifetime costs compared with control (US$7,603 and US$3,233, respectively), whereas amlodipine increased lifetime costs by US$300. Improvements were attributed to reductions in the cumulative incidence of end-stage renal disease with early use of irbesartan.Treating hypertensive diabetic patients with early irbesartan was projected to be life extending and cost saving, and to reduce the incidence of ESRD in Taiwan. |
