title: [Atenolol or metoprolol as beta-blocker in the treatment of hypertension].
abstract: Recently the guideline committee of the Dutch College of General Practitioners advocated the use of metoprolol instead of atenolol in patients with an indication for beta-blockers. This recommendation was based on a recent meta-analysis in The Lancet in which no effect was observed in favour ofatenolol compared with placebo on all-cause mortality, cardiovascular mortality and myocardial infarction. Atenolol also had a higher total mortality and stroke risk compared with other antihypertensive agents. Apart from the presence of statistical heterogeneity and the inappropriate use of a fixed-effect model, the studies referred to in this meta-analysis were also clinically heterogeneous. Furthermore, in most studies, only older patients were included. In older patients with hypertension, it is known that beta-blockers are less effective than diuretics or calcium antagonists. Comparative trials between atenolol and metoprolol in the treatment of hypertension have not been performed with regard to cardiovascular endpoints. We conclude that there is no evidence that atenolol is better or worse than metoprolol in the treatment of the hypertensive patient. For the treatment of patients with heart failure, however, lipophilic beta-blockers such as metoprolol may be preferred, as these drugs have been more thoroughly evaluated for this indication.
