An iron-based compound encapsulated in lipid nanoparticles completely eliminated tuberculosis in the lungs of mice after 30 days of treatment, according to a study by the Tuberculosis Research Laboratory at the Araraquara School of Pharmaceutical Sciences of São Paulo State University (FCFAr-UNESP) in Brazil. The study was published in the journal ACS Omega. The results suggest a possible new path for shorter, less toxic, and more effective therapies against resistant bacteria, one of the greatest challenges currently facing the fight against the disease.
