Continuing Education Case Study Quiz 

Goal—The goal of this program is to educate pharmacists about the use of dolutegravir for the treatment of patients with HIV-1. 

ObjectivesAt the completion of this program, the reader will be able to: 

  1. Describe the pharmacology and pharmacokinetics of dolutegravir.
  2. Discuss the risks associated with the use of dolutegravir.
  3. Discuss the dosage, reconstitution, and administration of dolutegravir for an individual patient.
  4. Apply the information on the use of dolutegravir to a case study.

    1. 20 mg.
    2. 35 mg.
    3. 45 mg.
    4. 50 mg.
  4. Administration of dolutegravir with food:
    1. Slows the rate and increases the extent of absorption.
    2. Slows the rate and decreases the extent of absorption.
    3. Speeds the rate and decreases the extent of absorption.
    4. Speeds the rate and increases the extent of absorption.
  5. Patients at increased risk for development of transaminase elevations with the use of dolutegravir include those with:

    2. Greater with raltegravir than with dolutegravir.
    3. The same with dolutegravir as with raltegravir.
    4. Not evaluated with either drug.
  7. Dolutegravir should not be administered within 2 hours before or 6 hours after:

Case History

R.C. is a 27-year-old woman, weighing 65 kg, with diagnoses of HIV-1 (viral load greater than 100,000 copies/mL), drug-induced diabetes, drug-induced hyperlipidemia, and no history of hepatic or renal failure. Her current medications include tenofovir disoproxil fumarate, emtricitabine, and efavirenz in a single tablet once daily at bedtime, an ethinyl estradiol/norgestimate oral contraceptive daily, daily multivitamin, metformin 1,000 mg twice daily, and simvastatin 10 mg once daily. Prior to her current antiretroviral regimen, she had been treatment naïve. In an effort to reduce her viral load, a regimen including abacavir, lamivudine, and dolutegravir has been recommended to replace her current antiviral regimen.

  1. What is the appropriate starting dose of dolutegravir for R.C.?
    1. 50 mg once daily
    2. 100 mg once daily
    3. 50 mg twice daily
    4. 50 mg every other day
  2. Which of the following adjustments to R.C.’s therapy may need to be performed after initiating the dolutegravir-containing regimen?
    1. Increase the dose of simvastatin
    2. Decrease the dose of metformin
    3. Increase the dose of ethinyl estradiol/norgestimate
    4. Decrease the dose of tenofovir
  3. Two months after initiating the new regimen, R.C. developed an infection at the site of a surgically repaired compound fracture requiring therapy with a fluoroquinolone and rifampin for several months. What dose of dolutegravir should R.C. now receive?
    1. 50 mg once daily
    2. 100 mg once daily
    3. 50 mg twice daily
    4. 50 mg every other day
  4. What monitoring should be performed for R.C. before and during treatment with dolutegravir?
    1. HIV-1 RNA and CD4 count
    2. Serum lipase
    3. Slit lamp eye exam
    4. Serum creatinine and BUN
  5. The dose of dolutegravir recommended for pediatric patients is:
    1. The same as the adult dose.
    2. Limited to 50 mg once daily.
    3. 50 mg twice daily due to their higher clearance.
    4. Weight-based up to a maximum of 1 mg/kg/day.
