A patient with a confirmed penicillin allergy requires antibiotic therapy for community-acquired pneumonia. Considering the provided pharmacological profiles, which of the following represents the MOST judicious monotherapeutic approach?
- Azithromycin, owing to its distinct mechanism of action circumventing beta-lactam hypersensitivity and established efficacy in pneumonia. (correct)
- Augmentin, administered with a prophylactic antihistamine to mitigate potential cross-reactivity in patients with reported penicillin allergies.
- Amoxicillin, as penicillin allergies are frequently overstated and a graded challenge may be safely undertaken in a controlled setting.
