Conditions

Standard treatment for tuberculosis includes isoniazid, which is an effective first-line anti-tuberculosis drug. Some patients develop drug-induced liver injury during treatment, which may lead to treatment interruption or complications. Genetic variation in the N-acetyltransferase 2 gene influences isoniazid metabolism. Tuberculosis, Isoniazid, NAT 2
