Since angina occurs when oxygen demand of the heart exceeds supply,Lopressor is helpful in treating angina. Headache, somnolence, nightmares, and insomnia have also been reported. Respiratory: Wheezing bronchospasm and dyspnea have been reported in about 1 of 100 patients.

The risk of precipitating adverse cardiac events e. If beta-blocker therapy is continued, it should be noted that the reduced ability of the heart to respond to beta-adrenergically mediated sympathetic reflex stimuli may augment the risks of general anesthesia and surgical procedures.
