Beta-blockers are a family of
drugs used to treat a variety of mainly
heart-related conditions. Beta-blockers are generally prescribed to lower the heart's workload by "blocking" the heart's "beta" receptors. Beta-blockers can also treat miscellaneous other conditions such as
tremors, migraine
headaches, and
glaucoma.
Beta-blockers can sometimes cause dangerously
low heart rates, worsen
respiratory conditions such as
asthma or
emphysema, and they may be associated with other conditions such as
depression.
Two recent studies of Carvedilol and Bucindolol (both beta-blockers) found that they are not necessarily beneficial for all heart failure patients. Although the studies found that beta-blockers generally reduced the chance of death, patients who suffered from the most severe cases of heart failure only received marginal, if any, benefit from the medication.
Some common brands of beta-blockers prescribed in the United States include Betapace, Cartrol, Lopressor, Sectral and Visken.
