It is an important chemical used as a prodrug, which is metabolized in the body to isonicotinic acid (INA) and hydrazine. INH is primarily known for its use as a first-line antituberculosis drug, as it inhibits the synthesis of mycolic acids, which are essential components of the cell wall in Mycobacterium tuberculosis. The drug is effective in treating both active and latent tuberculosis, and it is often used in combination with other medications to prevent the development of drug-resistant strains.
