While treatment with free Qc reduced the lesion sizes and parasite loads by 38 and 71%, respectively, LNC-Qc produced 64 and 91% reduction, respectively. The antileishmanial efficacy of PQc was similar but not as potently improved by encapsulation as Qc. None of the treatments increased aspartate aminotransferase, alanine aminotransferase or creatinine serum levels. These findings indicate that when encapsulated in LNC, Qc and, to a lesser extent, PQc can safely produce an enhanced antileishmanial effect even at a 40-fold lower dose, with implications for the development of a new oral drug for cutaneous leishmaniasis.<\/jats:p>","DOI":"10.1017\/s003118201700097x","type":"journal-article","created":{"date-parts":[[2017,6,27]],"date-time":"2017-06-27T10:18:40Z","timestamp":1498558720000},"page":"1769-1774","update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":35,"title":["Lipid-core nanocapsules increase the oral efficacy of quercetin in cutaneous leishmaniasis"],"prefix":"10.1017","volume":"144","author":[{"given":"A.
