4 Background: First vs. Best
Data source: Core messages from this analysis of the 26 discrete classes discovered to date: Of these, 12 classes have one drug whereas one class (beta-lactams) has 63 drugs. When more than one in a class, the span from first to next (2nd in class) ranges from a few years to decades. Time from first to last is usually decades. Summary Singletons and multi-drug classes occur at similar rates First-in-class is not necessarily best Decoding of the more obscure names Macrocycle = Fidaxomycin; Ansamycin = Rifaximin; Pseudomonic acid = Mupirocin (topical); Fusafungin = fusafungine; Peptides = Gramicidin S WHO PPL, CDC, & ESKAPE
