Which of the following is NOT one of the first-line drugs used to treat tuberculosis (TB)?

Amphotericin B is not one of the first-line drugs used to treat tuberculosis (TB). It is primarily an antifungal medication used to treat severe fungal infections, such as those caused by Candida and Aspergillus species. The first-line medications for TB typically include Rifampin, Isoniazid, Pyrazinamide, and Ethambutol. Rifampin and Isoniazid are particularly critical components of TB treatment due to their effectiveness in targeting the bacteria responsible for the infection, Mycobacterium tuberculosis. Streptomycin, while not a first-line agent in many modern treatment regimens, was historically used in treating TB and may still be applied in certain resistant cases. However, Amphotericin B has no role in TB treatment, emphasizing that it is not part of the essential pharmacotherapy for this disease.
