Resistance to last-line antibiotics

The increasing resistance to antibiotics and lack of antibiotics with new mechanisms of action against Gram-negative bacteria has caused the revival of old, formerly abandoned, drugs as last options. The first ones to regain popularity were the polymyxins, colistin and polymyxin B. Developed in the 1950s, the polymyxins fell out of favor due to toxic adverse effects such as kidney damage and affecting the nervous system. Current, more pure, formulations coupled with better understanding of their pharmacology have made the adverse reactions more rare and manageable.
