[Differential therapy with beta blockers. What is their value, what are the risks?].

The selective beta blockers metoprolol, bisoprolol and atenolol, but also the non-selective beta blocker carvedilol, are drugs with individually specific properties that are widely prescribed for a wide range of indications. Modern beta blockers are safe drugs with a low profile of side effects, which, applied with proper consideration being given to contraindications, rarely produce serious side effects such as bradyarrhythmia, bronchial obstruction, or aggravation of heart failure. Their prognostic benefit, for example, in the treatment of post-myocardial infarction patients, or in cardiac insufficiency, has been demonstrated in large randomized clinical trials.
