[Effect of antitubercular preparations on enzyme activity of erythrocytes]. / Vliianie protivotuberkuleznykh preparatov na aktivnost' nekotorykh fermentov v éritrotsitakh.

It was established experimentally that antituberculous agents (isoniazide, rifampicin, methazid, ethambutol, PAS) and their combination (isoniazide + rifampicin + PAS; isoniazide + PAS; methazid + PAS) inhibit erythrocytic glucoso-6-phosphate-dehydrogenase, glycerophosphate-dehydrogenase. This should be considered in instituting individual antituberculous therapy.
