Novel antibiotics: are we still in the pre-post-antibiotic era?

Therapeutic efficacy and safety in infections due to multidrug-resistant bacteria can be improved by the clinical development of new compounds and devising new derivatives of already useful antibiotics. Due to a striking global increase in multidrug-resistant Gram-positive but even more Gram-negative organisms, new antibiotics are urgently needed.

This paper provides a review of novel antibiotic compounds which are already in clinical development, mainly in phase III clinical trials.

Each of these new trials increases the possibility of new antibiotics receiving approval.
