DescriptionLefamulin is a pleuromutilin antibiotic used for the treatment of bacterial community-acquired pneumonia. A pleuromotilin is a more recently developed type of antibiotic that is derived from the fungus, Pleurotus mutilus.[A183206] Lefamulin is available in intravenous and oral preparations and was granted FDA approval in August 2019.[L8093] This drug is the first semi-synthetic pleuromutilin that has been designed for systemic administration. Lefamulin features a novel mechanism of action that shows benefit against resistant bacteria that cause pneumonia.[A183161] The chemical structure of lefamulin contains a tricyclic mutilin core that is necessary for some of its antimicrobial activity.[A183167]

Brand NamesXenleta
IndicationLefamulin is indicated to treat adults diagnosed with community-acquired bacterial pneumonia (CABP) that is caused by susceptible bacteria. Its use should be reserved for confirmed susceptible organisms or a high probability of infection with susceptible organisms. The list of susceptible bacteria includes Streptococcus pneumoniae, Staphylococcus aureus (methicillin-susceptible), Legionella pneumophila, Haemophilus influenza, Chlamydophila pneumoniae, and Mycoplasma pneumoniae.[L8093]
