  Purpose

Obesity is known to affect the concentrations of certain medications in the body. Levofloxacin is a commonly used antibiotic. Based on what the investigators know about levofloxacin and how it moves through the body, obesity may affect levofloxacin concentrations. This study aims to show the effect of obesity on levofloxacin concentrations.

The hypothesis is as follows: A 750 mg intravenous (IV) dose of levofloxacin administered to severely obese, critically ill patients will yield serum concentrations that are likely to be therapeutic.
