The increased raltegravir exposure observed with once-weekly rifapentine was safe and tolerable. Once-weekly rifapentine can be used with raltegravir to treat latent tuberculosis infection in patients who are infected with HIV.

BACKGROUND: A number of individual high-performance liquid chromatography (HPLC) procedures exist for the analysis of maltol, theobromine, ethyl maltol, catechin, vanillic acid, caffeine, vanillin, epicatechin, and ethyl vanillin. A single procedure utilizing simple sample preparation and less sophisticated equipment would be advantageous for the analysis of different sample types containing these compounds.
