Answer to Question 1

ANS: B
Rifapentine is indicated only for pulmonary TB. Rifapentine's toxicity is similar to that of rifampin. Rifapentine is well absorbed. Both drugs stain contact lenses.

Answer to Question 2

ANS: A
Rifabutin is used off-label as an alternative to rifampin to treat TB in patients with HIV, because it has less impact on the metabolism of protease inhibitors. The effects of rifapentine on protease inhibitors is similar to those of rifampin. Pyrazinamide is not indicated.
