Antitubercular Drugs Practice Test

Pretomanid is used in which context?

For latent TB infection. In combination regimens for highly drug-resistant TB. As monotherapy for MDR-TB. Not used in TB treatment.

Correct Answer:

In combination regimens for highly drug-resistant TB.

Explanation:

Pretomanid is used in combination regimens for highly drug-resistant TB. It is not used for latent TB infection, and it should not be used as monotherapy for MDR-TB because TB treatment relies on multiple drugs to prevent resistance and ensure effective killing of the bacteria. In practice, pretomanid is included with other drugs, most commonly bedaquiline and linezolid, as part of regimens for adults with MDR-TB or XDR-TB that have limited treatment options. This combination approach is what makes it the appropriate context among the choices.
