title: Economics of antihypertensive therapy in the elderly.
abstract: Because of the high incidence of morbidity and mortality associated with hypertension in the elderly, the treatment of hypertension in this patient group must involve consideration of clinical, humanistic and economic outcomes. The most frequently used method of pharmacoeconomic analysis for antihypertensive therapy involves cost-effectiveness analysis, although several other methods are available. Current evidence reveals a trend toward cost effectiveness of antihypertensive treatment in elderly patients. However, these formal analyses are limited by the need for extrapolation of data regarding efficacy and level of risk from epidemiological and randomised trials, information which is often lacking. To incorporate economic factors into clinical decision making, other measures of economic impact should be explored. The economic impact of antihypertensive therapy is affected by the level of risk for the patient and the efficacy of the treatment. Data indicate that the risk of morbidity and mortality related to hypertension increases with age and that current antihypertensive drugs reduce this risk. When choosing an antihypertensive agent, the following parameters should be considered: acquisition cost, likelihood of adverse effects and other determinants of treatment adherence, and individual predictors of response. The economic outcomes will be maximised if prudent drug selection is supplemented by appropriate diagnostic and classification procedures and reduction of cardiovascular risk factors other than hypertension. The accumulation of data addressing the risks and benefits of therapy for the very old and the comparative efficacy of newer antihypertensive therapies will further clarify the decision-making process.
