A patient with chronic bronchitis is hospitalized. Which medication is contraindicated for him?

In the case of a patient with chronic bronchitis, the use of theophylline is contraindicated primarily due to its narrow therapeutic index and the potential for significant side effects, especially in patients with underlying respiratory disease. Theophylline is a bronchodilator that can increase heart rate, cause gastrointestinal disturbances, and lead to potential toxicity with symptoms such as nausea, vomiting, and arrhythmias. In individuals with chronic bronchitis, who often have compromised pulmonary function and possibly other comorbidities, the risk of adverse effects is heightened, making it less suitable for management of their condition.

Albuterol, levofloxacin, and methylprednisolone are appropriate choices for managing acute exacerbations of chronic bronchitis. Albuterol is a short-acting bronchodilator that helps relieve bronchospasm, levofloxacin is an antibiotic effective against respiratory pathogens, and methylprednisolone is a corticosteroid that can reduce inflammation. These medications can be crucial in providing relief and managing symptoms during an acute exacerbation.
