Increased Doses Lead to Higher Drug Exposures of Levofloxacin for Treatment of Tuberculosis
Keyword(s):
ABSTRACTPatients with multidrug-resistant tuberculosis in Peru and South Africa were randomized to a weight-banded nominal dose of 11, 14, 17, or 20 mg/kg/day levofloxacin (minimum, 750 mg) in combination with other second-line agents. A total of 101 patients were included in noncompartmental pharmacokinetic analyses. Respective median areas under the concentration-time curve from 0 to 24 h (AUC0−24) were 109.49, 97.86, 145.33, and 207.04 μg · h/ml. Median maximum plasma concentration (Cmax) were 11.90, 12.02, 14.86, and 19.17 μg/ml, respectively. Higher levofloxacin doses, up to 1,500 mg daily, resulted in higher exposures.
