Levels of acetyl hydrazines and rate of acetylation of isoniazid in adult tuberculosis patients
Indian J Physiol Pharmacol.
1985 Apr-Jun.
Abstract
Patients suffering from pulmonary tuberculosis were investigated for the levels of isoniazid (INH) and its metabolites viz. acetyl-INH, mono and diacetyl hydrazines and ammonia. It was observed that 50% of the patients are slow inactivators of INH and almost all show an increase in circulating levels of NH3 at 6 hrs. Mono and diacetyl hydrazine levels in blood and urine were detectable in all the patients up+o 24 hrs though the maximum levels were observed at different intervals after the intake of INH.
