What is the most effective antibioticd in pneumonia?

Depends!: The best antibiotic for any given pneumonia depends upon the causative agent. In other words, different bacteria will respond to different antibiotics. Worse, viral pneumonias won't respond at all. So you need to know what caused the pneumonia in the first place. While we wait for the answer, we take an educated guess by starting some antibiotic. If possible, we try to vaccinate against common pne.

Depends: This questions can vary depending on whether the pneumonia is acquired in someone recently hospitalized or in the hospital versus in the community and whether the patient had underlying diseases like emphysema. There is no one best treatment. Antibiotics are selected based on the above medical situations, and then tailored to a germ grown in the lab from a sputum or blood sample if possible.
