Each year 25 000-32 000 children develop rifampicin- or multidrug-resistant tuberculosis (RR/MDR-TB), and many more require preventive treatment. Levofloxacin is a key component of RR/MDR-TB treatment prevention, but the existing pharmacokinetic data in have not yet been comprehensively summarized. We aimed to characterize levofloxacin pharmacokinetics through an individual patient meta-analysis available studies determine optimal dosing children.
