Q

VK is a 67-year-old female with diabetes, overactive bladder and hypothyroidism who has been started on Cipro for treatment of a urinary tract infection, based on susceptibility testing. All of the following counseling points are appropriate for VK EXCEPT:

A. This medication can cause tendon rupture.

B. Separate this medication from antacids such asMaalox.

C. This medication is associated with a risk of myelosuppression.

D. Thismedication can make the skin more sensitive to the sun. Use sunscreen and protective clothing.

E. Monitor blood glucose carefully while taking this medication if you have diabetes.

A

This medication is associated with a risk of myelosuppression.

Quinolones can cause many CNS toxicities (including seizures) and muscle toxicities (including tendon rupture).

They cause photosensitivity.

They should be separated from divalent cations to avoid chelation and reduced absorption.

Quinolones can cause hypoglycemia or hyperglycemia, so patients with diabetes should monitor blood glucose closely during therapy.

Q

Extended infusion piperacillin-tazobactam is a dosing strategy that optimizes which of the following pharmacodynamic parameters?

A. Peak:MIC ratio

B. AUC:MIC ratio

C. Peak concentration

D. Time above MIC (T > MIC)

E. Minimum bactericidal concentration

A

Time above MIC (T > MIC)

As a beta-lactam antibiotic, piperacillin/tazobactam kills or inhibits bacterial growth when drug concentrations exceed the minimum inhibitory concentration (MIC).

Extending the infusion (from the traditional 30 minutes to infusing over 4 hours) results in greater T > MIC and is one way to optimize the activity of beta-lactams and effectively treat more resistant (higher MIC) organisms.

Q

KD is a 35-year-old female with no known past medical history. She is married to an HIV-positive man. She has received a prescription for pre-exposure prophylaxis. Which labs must be performed before beginning therapy? (Select ALL that apply.)

A. TB skin test

B. CD4+ count

C. HIV test

D. Hepatitis B test

E. Hepatitis A test

A

HIV test
Hepatitis B test

Patients eligible for pre-exposure prophylaxis (PrEP) must be screened and test negative for HIV prior to initiation and then every 3 months after starting PrEP. It is important to evaluate this information, as the 2-drug NRTI PrEP regimen is not adequate for treatment of a patient diagnosed with HIV.

Patients must also be screened for hepatitis B and STI’s. Abrupt discontinuation of PrEP in patients with hepatitis B can exacerbate the condition.

A

Spontaneous bacterial peritonitis

PO only

Rifaximin (Xifaxin) is an antibacterial agent that is structurally related to rifampin.

It is indicated for the treatment of non-invasive E. colitravelers’ diarrhea, for reduction in the risk of overt hepatic encephalopathy and for IBS-D.

Since systemic drug absorption is minimal, it is not useful for spontaneous bacterial peritonitis (SBP).

Q

Which of the following statements are correct with regard to sulfamethoxazole/trimethoprim? (Select ALL that apply.)

A. It is a potent hepatic enzyme inducer resulting in reduced drug concentrations.

B. It has excellent bioavailability, thus can transition from intravenous to oral formulations in a 1:1 fashion.

C. It is active against Gram-positive pathogens, including Staphylococci, Gram-negative pathogens and opportunistic pathogens.

D. It should be avoided in a patient with a G6PD deficiency.

E. A negative Coombs test with sulfamethoxazole/trimethoprim indicates hemolytic anemia.

A

It has excellent bioavailability, thus can transition from intravenous to oral formulations in a 1:1 fashion.

It is active against Gram-positive pathogens, including Staphylococci, Gram-negative pathogens and opportunistic pathogens.

It should be avoided in a patient with a G6PD deficiency.

TMP/SMX is a potent CYP2C9 inhibitor (not inducer). It has 1:1 conversion from IV:PO dosing.

It is a broad spectrum agent with excellent Gram-positive, Gram-negative (not Pseudomonas) and opportunistic pathogen coverage.

It is partially cleared by the kidney and should be dosed reduced for CrCl < 30 mL/min.

A positive Coombs test in the labs (along with decreasing hemoglobin/hematocrit) would indicate the presence of hemolytic anemia and Bactrim should be discontinued.

A

Active against most aerobic Gram-negative pathogens

Demonstrate post-antibiotic effect

Demonstrate concentration-dependent bacterial killing

Aminoglycosides are concentration-dependent killers and are active against Pseudomonas.

They are cleared by the kidney and associated with nephrotoxicity and ototoxicity, especially when trough levels remain high or when given for prolonged treatment courses.

When used in complicated Gram-positive infections (Staphylococcus and Enterococcus) they are used for synergy, which means that they must be given in combination with beta-lactams or vancomycin.

Q

BJ is on tobramycin IV every 8 hours for treating a gram-negative infection and his levels are reported as a peak of 8.3 mcg/mL and a trough of 2.5 mcg/mL. Which of the following recommendations should the pharmacist make to the medical team?

A. Increase the dose of tobramycin

B. Decrease the dose of tobramycin

C. Extend the dosing interval of tobramycin

D. Shorten the dosing interval of tobramycin

E. Continue the current regimen

A

Extend the dosing interval of tobramycin

The peak of tobramycin is within range, but the trough level is above the goal level(it should be less than 2 mcg/mL and ideally less than 1.5 mcg/mL).

By extending the dosing interval, the trough level will decrease and the toxicity risk is lowered without decreasing the peak for this concentration-dependent drug.

Q

JPhas a blood culture report showing Gram-positive cocci resembling Streptococci, Klebsiella pneumoniaeand anaerobes. Which of the following medications would provide adequate coverage for these organisms?

A. Ertapenem

B. Rifaximin

C. Metronidazole

D. Fosfomycin

E. Ciprofloxacin

A

Ertapenem

Carbapenems are very broad-spectrum antibiotics.

They cover gram positives, gram negatives and anaerobes.

Rifaximin, metronidazole and fosfomycin have a much narrower spectrum.

Ciprofloxacin does not have reliable strep coverage, nor does it cover anaerobes.

95
Q

Carbapenem Meds

A

Doripenem

Imipenem/Cilastatin (Primaxin I.V.)

Meropenem

Meropeneme/Vaborbactam (Vabomere)

A

All active against ESBL-producing organisms and (except ertapenem) Pseudomonas

Do not use with penicillin allergy

Seizure risk (with higher doses, failure to dose adjust in renal dysfunction, or use of imipenem/cilastatin)

97
