In this work, we investigated the ability of \u03b2-cyclodextrin to enhance the oral absorption of antimony and to promote the oral efficacy of meglumine antimoniate against experimental cutaneous leishmaniasis. The occurrence of interactions between \u03b2-cyclodextrin and meglumine antimoniate was demonstrated through the changes induced in the spin lattice relaxation times of protons in both compounds. When free and complexed meglumine antimoniate were given orally to Swiss mice, plasma antimony levels were found to be about three times higher for the meglumine antimoniate-\u03b2-cyclodextrin complex than for the free drug. Antileishmanial efficacy was evaluated in BALB\/c mice experimentally infected with\n            <jats:italic>Leishmania amazonensis<\/jats:italic>\n            . Animals treated daily with the complex (32 mg of Sb\/kg of body weight) by the oral route developed significantly smaller lesions than those treated with meglumine antimoniate (120 mg of Sb\/kg) and control animals (treated with saline). The effectiveness of the complex given orally was equivalent to that of meglumine antimoniate given intraperitoneally at a twofold-higher antimony dose. The antileishmanial efficacy of the complex was confirmed by the significantly lower parasite load in the lesions of treated animals than in saline-treated controls. This work reports for the first time the effectiveness of an oral formulation for pentavalent antimonials.\n          <\/jats:p>","DOI":"10.1128\/aac.48.1.100-103.2004","type":"journal-article","created":{"date-parts":[[2003,12,24]],"date-time":"2003-12-24T02:03:22Z","timestamp":1072231402000},"page":"100-103","update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":69,"title":["Oral Delivery of Meglumine Antimoniate-\u03b2-Cyclodextrin Complex for Treatment of Leishmaniasis"],"prefix":"10.1128","volume":"48","author":[{"given":"Cynthia","family":"Demicheli","sequence":"first","affiliation":[{"name":"Departamento de Qui\u0301mica, ICEX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rosemary","family":"Ochoa","sequence":"additional","affiliation":[{"name":"Departamento de Qui\u0301mica, ICEX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose\u0301 B.
