Isoniazid

Isoniazid is an antibiotic used primarily for the treatment and prevention of tuberculosis (TB). It is one of the most effective first-line medications against TB and is often used in combination with other drugs to prevent drug resistance. Isoniazid works by inhibiting the growth of Mycobacterium tuberculosis, the bacteria responsible for TB. This medicine is widely used in both active and latent TB infections to prevent their spread and complications.
