The presence of this genotype in CYP2E1 may be associated with an increased risk of drug-induced hepatotoxicity from isoniazid treatment. Curr Med Chem. Isoniazid (INH) is used for treatment of tuberculosis (as part of combination therapy) or for latent tuberculosis infection (as monotherapy or part of combination therapy). Liver function tests are not a substitute for a clinical evaluation at monthly intervals or for the prompt assessment of signs or symptoms of adverse reactions occurring between regularly scheduled evaluations. [30][31], Isoniazid decreases the metabolism of carbamazepine, thus slowing down its clearance from the body. Monitor therapy, Dofetilide: CYP3A4 Inhibitors (Weak) may increase the serum concentration of Dofetilide. It can be prevented by administration of pyridoxine whenever isoniazid is given. [37] KatG catalyzes the formation of the isonicotinic acyl radical, which spontaneously couples with NADH to form the nicotinoyl-NAD adduct. Manzano JS, Hou W, Zalesskiy SS, Frei P, Wang H, Kitson PJ, Cronin L. Nat Chem. Isoniazid, also known as isonicotinic acid hydrazide ( INH ), is an antibiotic used for the treatment of tuberculosis.

Mechanisms of action of isoniazid For decades after its introduction, the mechanisms of action of the front-line antituberculosis therapeutic agent isoniazid (INH) remained unclear. [13] Evidence suggests that isoniazid prevents mycolic acid synthesis in M. avium complex as in M. tuberculosis[14] and although this is not bactericidal to M. avium complex, it greatly potentiates the effect of rifampicin. Readily absorbed following oral administration; however, may undergo significant first pass metabolism. Approximate case rates by age are as follows: less than 1/1,000 for persons younger than 20 years of age, 3/1,000 for persons in the 20 to 34 year age group, 12/1,000 for persons in the 35 to 49 year age group, 23/1,000 for persons in the 50 to 64 year age group, and 8/1,000 for persons older than 65 years. Three pharmaceutical companies unsuccessfully attempted to patent the drug at the same time,[44] the most prominent one being Roche, which launched its version, Rimifon, in 1952. For decades after its introduction, the mechanisms of action of the front-line antituberculosis therapeutic agent isoniazid (INH) remained unclear. 2004 Aug;186(16):5427-31. doi: 10.1128/JB.186.16.5427-5431.2004.
