Increased Doses Lead to Higher Drug Exposures of Levofloxacin for the Treatment of Tuberculosis. Antimicrob Agents Chemother. 2018 Jul 16;: Authors: Peloquin CA, Phillips PPJ, Mitnick CD, Eisenach K, Patientia RF, Lecca L, Gotuzzo E, Gandhi NR, Butler D, Diacon AH, Martel B, Santillan J, Hunt KR, Vargas D, von Groote-Bidlingmaier F, Seas C, Dianis N, Moreno-Martinez A, Kaur P, Horsburgh CR Abstract Patients with multidrug-resistant tuberculosis in Peru and South Africa were randomized to weight-banded nominal doses of 11, 14, 17 or 20 mg/kg/day levofloxacin (minimum 750 mg) in combination with other second-line agents. 101 patients were included in noncompartmental pharmacokinetic analyses. Respective median AUC0-24 were 109.49, 97.86, 145.33 and 207.04 h*mcg/ml. Median Cmax were 11.90, 12.02, 14.86, and 19.17 mcg/ml. Higher levofloxacin doses, up to 1500 mg daily, resulted in higher exposures. ClinicalTrials.gov Identifier: NCT01918397. PMID: 30012767 [PubMed - as supplied by publisher]
