Pneumonia is a bacterial lower respiratory tract infection that has a high morbidity rate. The gram-negative pathogen is a significant cause of nosocomial infections and ventilator-associated pneumonias and is mainly treated by carbapenems. Doripenem is a carbapenem drug, which has a broad-spectrum antibacterial activity.
