From the Guidelines
For patients with stage 4 chronic kidney disease (CKD) requiring broad-spectrum intravenous antibiotics, piperacillin-tazobactam (2.25g IV q8h) is a suitable option with dose adjustments, as it provides coverage against gram-positive, gram-negative, and some anaerobic organisms while accommodating the significantly reduced glomerular filtration rate (15-29 mL/min) in CKD stage 4 1.
Key Considerations
- The choice of antibiotic should be based on the susceptibility pattern of the colonizing bacteria, and dose adjustments should be made according to the patient's renal function 1.
- Aminoglycosides should be avoided due to their nephrotoxicity risks, especially in patients with CKD 1.
- Vancomycin can be added for MRSA coverage, but careful monitoring of trough levels and dose adjustment based on levels and renal function are necessary 1.
- Consultation with a clinical pharmacist is valuable for precise dosing and monitoring of drug levels 1.
Antibiotic Options
- Piperacillin-tazobactam (2.25g IV q8h) is a suitable option for broad-spectrum coverage, with dose adjustments based on renal function 1.
- Other options, such as ceftazidime and meropenem, may also be considered, but their use should be guided by the susceptibility pattern of the colonizing bacteria and the patient's renal function 1.
Monitoring and Precautions
- Close monitoring of renal function is necessary during antibiotic therapy, as patients with CKD have limited renal reserve and are at higher risk for further kidney injury from medications or sepsis 1.
- Drug levels should be monitored when applicable, and dose adjustments should be made accordingly 1.

From the Research
Broad Spectrum IV Antibiotic Options for Patients with CKD 4
- Patients with chronic kidney disease (CKD) stage 4 require careful consideration when selecting broad-spectrum intravenous (IV) antibiotics due to the potential for nephrotoxicity and altered drug clearance 2.
- The choice of antibiotic should be based on the patient's renal function, with dose adjustments made as necessary to prevent adverse effects 3.
- Meropenem, piperacillin/tazobactam, and cefepime are broad-spectrum antibiotics that can be used in patients with CKD 4, but their dosing regimens may need to be adjusted based on the patient's creatinine clearance 3, 4, 5, 6.
Antibiotic-Specific Considerations
- Meropenem may be a suitable option for patients with CKD 4, as it has been shown to have a lower risk of nephrotoxicity compared to piperacillin/tazobactam 5.
- Piperacillin/tazobactam, on the other hand, has been associated with a higher risk of nephrotoxicity and delayed renal recovery in critically ill patients 4, 5.
- Cefepime is another broad-spectrum antibiotic that can be used in patients with CKD 4, but its dosing regimen may need to be adjusted based on the patient's renal function 3, 6.
Dosing Considerations
- The dosing regimens for broad-spectrum antibiotics in patients with CKD 4 should be individualized based on the patient's renal function, with close monitoring of serum creatinine and urine output 2, 3, 6.
- Extended infusions of meropenem and piperacillin/tazobactam may be used to improve pharmacokinetic/pharmacodynamic target attainment, but augmented renal clearance can still affect target attainment 6.
