What is the first-line treatment for acute bacterial rhinosinusitis?

Amoxicillin-clavulanate is considered the first-line treatment for acute bacterial rhinosinusitis due to its effectiveness against the most common pathogens associated with this condition, particularly Streptococcus pneumoniae and Haemophilus influenzae. This antibiotic combination not only has the ability to kill bacteria but also features clavulanate, which inhibits the action of beta-lactamase enzymes produced by some resistant strains of bacteria, thus ensuring a broader spectrum of activity.

Choosing amoxicillin-clavulanate is aligned with current clinical guidelines that recommend initiating treatment with this antibiotic for patients who are experiencing moderate to severe symptoms or have a persistent illness lasting more than 10 days. The effectiveness of this regimen in reducing symptoms and preventing complications makes it the preferred choice in the management of acute bacterial rhinosinusitis.

Other options such as azithromycin, doxycycline, and ciprofloxacin are not first-line for this specific indication. Azithromycin is ineffective for the common pathogens of rhinosinusitis due to concerns about resistance and lack of coverage for typical bacterial strains. Doxycycline is typically reserved for cases where patients have an allergy to penicillin or other specific situations. Ciprofloxacin, while it has broad-spectrum coverage, is generally not
