Tuberculosis After Gastrectomy, Plasmatic Concentration of Antitubercular Drugs

We report pharmacokinetic data on two gastrectomized, patients affected by tuberculosis. Drugs plasmatic concentrations were measured after seven days of oral therapy by a validated high performance liquid chromatography-mass spectrometry (HPLC-MS) method and the area under the concentration-time-curve (AUC) over 24 hours (AUC(0-24)) was calculated. A sub-therapeutic level of isoniazid was foun...

Drug susceptibility of Mycobacterium tuberculosis to primary antitubercular drugs by nitrate reductase assay.

BACKGROUND & OBJECTIVES Rapid susceptibility testing of Mycobacterium tuberculosis strains is imperative for therapy selection but traditional drug susceptibility tests take weeks or are expensive. In this study we evaluated nitrate reductase assay which utilizes the detection of nitrate reduction as an indication of growth and therefore results can be obtained faster than by visual detection o...

Mycobacterium tuberculosis gyrase inhibitors as a new class of antitubercular drugs.

One way to speed up the TB drug discovery process is to search for antitubercular activity among compound series that already possess some of the key properties needed in anti-infective drug discovery, such as whole-cell activity and oral absorption. Here, we present MGIs, a new series of Mycobacterium tuberculosis gyrase inhibitors, which stem from the long-term efforts GSK has dedicated to th...

Pulmonary tuberculosis following partial gastrectomy.

Rifampin and Their Analogs: A Development of Antitubercular Drugs

There has been considerable interest in various analogues of antitubercular drugs particularly against multidrug and extensively drug resistant tuberculosis because mycobacterium species has developed resistant against available drugs. The currently used antitubercular also causes some serious toxic effects and also require long period of therapy for the treatment. Therefore, various new drugs ...
