Summary, in English
We investigated the activity of trimethoprim-sulfamethoxazole (SXT) against Mycobacterium tuberculosis. The MIC distribution of SXT was 0.125/2.4-2/38 mg/L for the 100 isolates tested, including multi- and extensively drug-resistant isolates (MDR/XDR-TB), whereas the intracellular MIC90 of sulfamethoxazole (SMX) for H37Rv was 76 mg/L. In an exploratory analysis using fAUC0-24h/MIC ≥25 as a potential target, the cumulative fraction response was ≥90% at doses ≥2400 mg of SMX. SXT is a potential treatment option for MDR/XDR-TB.
