Extended-spectrum penicillin is a group of antibiotics that has the widest antibacterial spectrum of all penicillins.[1] It is also called antipseudomonal penicillins.[citation needed] This group includes the carboxypenicillins and the ureidopenicillins. Note that aminopenicillins, in contrast, do not have activity against Pseudomonas species, as their positively-charged amino group does not hinder degradation by bacterially-produced beta-lactamases.
