Solithromycin is a fluoroketolide antibiotic of the macrolide class. It was developed for the treatment of community-acquired bacterial pneumonia and other infections caused by susceptible bacteria. As of 2024, solithromycin is not approved for clinical use in the United States or Europe, with development halted after regulatory concerns about liver safety.
