How does isoniazid cause hepatitis?
Chronic INH hepatotoxicity results in the induction of hepatocyte apoptosis, with associated disruption of mitochondrial membrane potential and DNA strand breaks. The most likely biochemical mechanism is that the metabolism of INH produces reactive metabolites that bind and damage cellular macromolecules in the liver.Feb 7, 2019

How does rifampin cause hepatitis?
Rifampicin occasionally interferes with bilirubin uptake and results in transient unconjugated hyperbilirubinemia without hepatocyte damage. However more commonly, it does contribute to conjugated hyperbilirubinemia by interfering with the bilirubin excretion by inhibiting the bile salt exporter pump (BSEP).
What causes toxic hepatitis?

Does rifampin cause liver damage?
Rifampin is associated with transient and asymptomatic elevations in serum aminotransferase and bilirubin levels and is a well known cause of clinically apparent, acute liver disease that can be severe and even fatal.Jun 10, 2018
