EDITOR,—The datasheet for Inderal (propranolol) states specifically that the drug is contraindicated in patients with asthma or a history of bronchospasm. Despite this, and despite the well known risks of non-selective ß blockers in patients with asthma, over the past few years Zeneca has received a number of reports of cases in which an asthmatic patient … viagra duration The potential interaction between beta-blockers and beta-agonists is a classic example of a pharmacodynamic drug interaction. It would appear that the administration of beta-blockers to patients taking beta-agonists should be avoided in all cases and some have recommended this action. However, differences in the activity of beta receptors and receptor selectivity of drugs binding to beta receptors add a level of complexity that precludes broad drug class–based interaction recommendations. Beta-blockers and Beta-agonists in Asthma Beta-agonists are commonly used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). Beta-blocker use in asthma has been widely studied. In general, cardioselective beta-blockers (eg, acebutolol, atenolol, bisoprolol, celiprolol, metoprolol) appear to be effective for the treatment of thyrotoxicosis, tachyarrhythmias, hypertension, heart failure, and acute coronary syndrome without increased risk of asthma exacerbation. In an analysis of 10 studies on the effect of beta-blockers in patients with asthma where selective beta-blockers were administered for up to 14 weeks, there was no change compared with placebo in FEV1, symptoms, or inhaler use.

Taylor, MD, Department of Cardiovascular Medicine, J3, Cleveland Clinic, 9500 Euclid Avenue, Cleveland, OH 44195; e-mail [email protected] Treatment with beta-adrenergic receptor blockers decreases the mortality rate in patients with coronary artery disease or heart failure, as well as during the perioperative period in selected patients (eg, those with a history of myocardial infarction, a positive stress test, or current chest pain due to myocardial ischemia). The current evidence supports giving beta-blockers to patients with coronary artery disease and chronic obstructive pulmonary disease (COPD) or asthma, which lowers the 1-year mortality rate to a degree similar to that in patients without COPD or asthma, and without worsening respiratory function. However, these data are from small trials in the 1970s and 1980s. On the other hand, not giving beta-blockers can pose a risk of death. It has long been suggested that beta-blockers—drugs commonly used to treat hypertension and other cardiovascular conditions—may be problematic in people with severe asthma or chronic obstructive pulmonary disease (COPD). This was due in large part to studies from the 1970s and 1980s, which suggested that the drugs amplify the sensitivity of lung tissues and, by doing so, increased the risk of bronchial spasms. But many of those assertions have since been challenged, with most experts today agreeing that the benefits of beta-blockers far outweigh the potential consequences. With the development of newer cardioselective beta-blockers, the risks are even less. Even so, care needs to be taken when beta-blockers are used in people with severe asthma or COPD to avoid potentially serious exacerbations. They were once considered off-limits for people with reactive lung disease (RAD) due to their generalized mechanism of action. The drugs block the effects of epinephrine, the hormone responsible for increases in heart rate.
