A non-cardioselective beta blocker propranolol was introduced in the therapy in the early 1960s.
Blockade of cardiac beta-1 adrenergic receptors results in decreased heart rate and blood pressure. The clinical beneﬁt of βblockade has been proven in a. Beta-Blockers in Clinical Practice.
The implementation of beta blockers in clinical practice is feasible and could be accelerated. Variety of pathologic settings including hypertension angina pectoris acute- and post-myocardial infarction and congestive heart failure. In daily clinical practice however prescription rates of beta-blockers and the doses taken are lower than might be expected based on the available evidence.

In multivariate analysis the use of beta blockers was independently associated with a better prognosis with a relative risk of 060 and a lower incidence of hospital admissions for worsening heart failure.
Beta-blockers have become one of the cornerstones of treatment of patients with heart failure HF and depressed left ventricular function but in clinical practice only 30-35 of patients achieve the therapeutic target dose as established in randomized clinical trials. Lindas PhD investigated clinical medication reviews in primary care and she has advocated strongly for the role of independent clinical pharmacists in PHOs and general. Although beta-blockers are widely used in routine clinical practice this analysis indicates that their overall clinical effect depends strongly on the clinical situation.

Beta-blockers seem to be underused especially in women and older adults of both sexes said Arno Hoes MD PhD of the University Medical Center Utrecht The Netherlands in an editorial. Beta-blockers started to be more widely used in clinical practice after the introduction of propranolol in 1964. The three beta-blockers shown to benefit survival in heart failure are either beta-1 selective metoprolol bisoprolol or block both beta and alpha receptors carvedilol.
How do beta-blockers work. Cacy or safety in many of these conditions. Some beta-blockers also bind to alpha receptors to some degree allowing them to induce a different clinical outcome when used in specific settings.
