Question:
A nurse is admitting a patient with congestive heart failure (CHF) treated with atenolol for an acute exacerbation of chronic obstructive pulmonary disease (COPD). The nurse notes a potential drug-to-drug interaction with one of the patient’s newly prescribed medications. Which of the following drugs should not be used to treat this patient’s COPD exacerbation?
A
albuterol
explanation
Albuterol should not be used. The patient takes atenolol for CHF which is a beta-blocker. Albuterol is a beta agonist that has the opposite pharmacological effect of atenolol. In a patient taking atenolol, the therapeutic capability of albuterol may be greatly decreased. Ipratropium, corticosteroids, and theophylline have no potential interaction with atenolol.
