Answer

The mainstay of drug therapy for bacterial pneumonia is antibiotic treatment. The choice of agent is based on the severity of the patient's illness, host factors (eg, comorbidity, age), and the presumed causative agent. Although intravenous (IV) penicillin G is currently not favored, doses in the range of 20-24 million U/d result in serum levels that exceed minimum inhibitory concentration (MIC) levels of most resistant pneumococci.
