First-Line Antibiotic Treatment of Aspiration Pneumonia
Clinical Scenario
Aspiration pneumonia requires prompt antibiotic therapy. This protocol covers the recommended first-line antibiotic approach, the preferred route of administration, and how renal function shapes management decisions.
Treatment Approach
The recommended first-line therapy is a beta-lactam/beta-lactamase inhibitor combination, with the oral route given as the priority. Dosing is adjusted according to renal function; the complete agent, dose selection, and 5-day duration criteria are contained in the full protocol.
Clinical Stability Targets — Evaluated at 72 Hours
- Temperature ≤ 37.8 °C
- Systolic blood pressure ≥ 90 mm Hg
- Heart rate ≤ 100/min
- Respiratory rate ≤ 24/min
- SpO₂ ≥ 90 % or PaO₂ ≥ 60 mm Hg in ambient air

- First choice: amoxicillin-clavulanic acid, oral or intravenous (IV) (Grade B-1)
- It is recommended to use the oral route as a priority (Grade B-1).
- The recommended treatment duration is 5 days in case of positive clinical course (Grade C-1).
- The positive clinical course is evaluated at 72 h by the presence of all of the following clinical stability criteria: Temperature ≤ 37.8 °C; Systolic blood pressure ≥ 90 mm Hg; Heart rate ≤ 100/min; Respiratory rate ≤ 24/min; SpO2 ≥ 90 % or PaO2 ≥ 60 mm Hg in ambient air.
