It works by enhancing the effects of a natural chemical in the body (GABA) to produce a calming effect on the brain and nerves, thereby alleviating symptoms of anxiety.

- A. Potassium level
- B. INR
- C. BUN
- D. Platelet count
Correct Answer: B

Which of the following drugs causes the most significant inhibition of metabolism of rifabutin?
- A. Zidovudine
- B. Ritonavir
- C. Enfuvirtide
- D. Nevirapine
Correct Answer: B
Rationale: Rifabutin, metabolized by CYP3A4, is affected by inhibitors. Zidovudine, enfuvirtide, and nevirapine don't strongly inhibit CYP3A4. St John's wort induces it, lowering levels. Ritonavir, a potent CYP3A4 inhibitor, significantly slows rifabutin metabolism, raising levels and toxicity risk (e.g., uveitis), the most impactful. This interaction requires dose adjustment, critical in HIV-TB co-treatment.
