What backs it

Boston Children's Hospital researchers redesigned lipid carriers to extend local anesthesia from 4-8 hours to 2-3 weeks in rats, using tetrodotoxin released gradually enough to remain safe while maintaining numbing effect.

Worth noting

Tested in rats; tetrodotoxin is not yet used commercially in patients. Nerve blocks last longer in humans, but human testing lies ahead.
