Which medication is commonly used to treat tuberculosis?

Isoniazid
Nevirapine
Amodiaquine
Bacille Calmette-Gurin (BCG)

The correct answer is: Isoniazid

Isoniazid is a cornerstone medication used in the treatment of tuberculosis (TB). It is specifically designed to kill the bacteria that cause TB and is most effective during the active disease stages. Isoniazid is often used in combination with other antitubercular agents to enhance efficacy and prevent resistance. This approach is crucial given the concern over multidrug-resistant TB, making isoniazid an essential part of guideline-based therapies for both active and latent TB infections. Other medications listed in the choices serve different purposes. Nevirapine is primarily an antiretroviral used in the treatment of HIV, while amodiaquine is an antimalarial drug. Additionally, Bacille Calmette-Gurin (BCG) is a vaccine for tuberculosis rather than a treatment; it is used to prevent the disease, particularly in countries with high TB prevalence. Therefore, isoniazid stands out as the specific medication that directly targets the treatment of tuberculosis.
