Ketek

What is Ketek?

Ketek (telithromycin) is anantibiotic medication that is used to treat certain respiratory infectionscaused by bacteria, such as bronchitis and pneumonia. While Ketek kills many types of bacteria thatinfect the lungs and sinuses, it does not kill viruses, such as those thatcause the common cold.

Ketek is manufactured by Sanofi-Aventis and was approved by the U.S. Food and DrugAdministration (FDA) in April 2004.
