Teicoplanin Dosing in Acute Kidney Injury
For patients with acute kidney injury, teicoplanin should be administered with a loading dose of 6-12 mg/kg every 12 hours for three doses, followed by a maintenance dose of 6-12 mg/kg once daily with dosing interval adjustments based on renal function severity. 1
Initial Loading Dose
- A loading dose of 25-30 mg/kg (based on actual body weight) is recommended for critically ill patients to rapidly achieve therapeutic drug levels due to expanded extracellular volume related to fluid resuscitation 1
- Loading doses of antimicrobials with low volumes of distribution (including teicoplanin) are not affected by alterations in renal function 1
- For serious infections, use the higher end of the dosing range (10-12 mg/kg) for the loading doses 1
Maintenance Dosing Based on Renal Function
- For moderate renal impairment: 6-12 mg/kg once daily 1, 2
- For severe renal impairment: 6-12 mg/kg every 2-3 days 3
- For patients on hemodialysis: 6-12 mg/kg every 3 days or post-dialysis 4
Target Trough Concentrations
- Target trough concentration (Cmin) should be 15-30 μg/ml for serious infections 2
- Pre-dose monitoring of trough concentrations is recommended to ensure therapeutic levels 1
- Achievement of Cmin ≥15 μg/ml without delay is necessary to improve clinical outcomes in patients with renal dysfunction 2
Monitoring Recommendations
- Measure trough levels before the 4th dose (after completing loading doses) 2
- For patients with AKI, more frequent monitoring may be required due to changing renal function 4
- Adjust subsequent doses based on measured trough concentrations and clinical response 2
Important Considerations
- The elimination half-life of teicoplanin increases significantly with decreasing renal function (from 41 hours in normal renal function to 163 hours in anuric patients) 4
- Renal clearance of teicoplanin correlates closely with creatinine clearance 4, 3
- Despite higher trough concentrations in renal dysfunction, nephrotoxicity rates remain acceptable when maintained within the 15-30 μg/ml range 2
Common Pitfalls to Avoid
- Inadequate loading doses leading to delayed achievement of therapeutic levels 1, 2
- Failure to adjust maintenance dosing intervals in severe renal dysfunction 4, 3
- Insufficient monitoring of trough concentrations, especially in patients with changing renal function 2
- Not considering the extended half-life of teicoplanin in renal dysfunction when planning dosing intervals 4
Remember that while the loading dose remains unchanged regardless of renal function, the maintenance dosing interval needs to be extended as renal function declines 4, 3.
