Mechanism of action

Retapamulin is a pleuromutilin antibiotic that selectively binds to the bacterial 50S ribosomal subunit and inhibits peptide bond formation, blocking protein synthesis. This mechanism is selective for bacteria and has minimal effect on human mitochondrial ribosomes. It is bacteriostatic, stopping bacterial growth rather than directly killing the organisms.
