Surotomycin

Surotomycin was an investigational oral antibiotic. This macrolide antibiotic was under investigation by Merck & Co (who acquired Cubist Pharmaceuticals) for the treatment of life-threatening diarrhea, commonly caused by the bacterium Clostridioides difficile.^[1] After reaching phase III in clinical trials, its production was discontinued in 2017 due to its non-superiority to current therapies.^[2][3]
