Short term anti-tubercular drug therapy and hepatic microsomal enzyme activity. Antipyrine metabolism as an index.

ABSTRACT

The effect of short course chemotherapy on the drug metabolising capacity of the liver was studied in 7 newly diagnosed pulmonary tuberculosis patients, using antipyrine as a model drug. Antipyrine elimination half-life and plasma clearance rate were not significantly altered by 3 weeks of therapy. It is concluded that short course chemotherapy does not affect antipyrine metabolising enzyme activity.
