Efepristin (RPR 106972) is an oral streptogramin consisting of two synergistic components RPR 112808 (pristinamycin IB) and RPR 106950 (pristinamycin IIB). It demonstrated activity against Gram-positive microorganisms in vitro and in vivo, including those with multi-drug resistance. The streptogramins inhibit bacterial growth by disrupting the translation of mRNA into protein.
