Does Azithromycin Cause QT Prolongation in Hospitalized Patients With Severe Community Acquired Pneumonia?

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01553734
Recruitment Status : Completed

Brief Summary:
The macrolide group of antibiotics can cause QT prolongation, and endanger the patient with life threatening arrythmias. QT prolongation caused by Azythromycin, a relatively new macrolide, is extremely rare, and was not reported in clinical trials. Our hypothesis is that patients hospitalized with severe community acquired pneumonia, usually with multiple comorbid conditions will have a higher rate of QT prolongation, compared to the clinical trials published

Condition or disease

Detailed Description:
Patients hospitalized with community aquired pneumonia will have their corrected QT measured daily during antibiotic therapy. Concomittant medications and electrolyte abnormalities that cause prolonged QT will be recorded
