Teicoplanin Dosing Regimen for a 60 kg Man with Oliguria and Impaired Renal Function
For a 60 kg man with oliguria and impaired renal function, the recommended teicoplanin dosing regimen is a loading dose of 6-12 mg/kg (360-720 mg) administered three times at 12-hour intervals, followed by a maintenance dose of 6-12 mg/kg every 48-72 hours depending on the severity of renal impairment. 1
Initial Loading Dose
- The loading dose remains the same regardless of renal function to rapidly achieve therapeutic levels 1
- For standard infections: 6 mg/kg (360 mg) three times at 12-hour intervals 1
- For severe infections (endocarditis, septic arthritis, complicated bacteremia): 12 mg/kg (720 mg) three times at 12-hour intervals 1, 2
- Loading doses are critical and should not be reduced even in patients with renal impairment 2, 1
Maintenance Dose Based on Renal Function
- For GFR 10-50 mL/min: 6-12 mg/kg (360-720 mg) every 48 hours 1
- For GFR <10 mL/min: 6-12 mg/kg (360-720 mg) every 72 hours 1
- For hemodialysis patients: 6 mg/kg (360 mg) once weekly after the loading doses 1
Dosing Considerations for Oliguria
- Oliguria indicates significant renal impairment, requiring extended dosing intervals 1
- The presence of oliguria suggests the need for the 48-72 hour maintenance dosing interval rather than the standard 24-hour interval 1
- Failure to extend dosing intervals appropriately can lead to drug accumulation and potential toxicity 1
Target Trough Concentrations
- For standard infections: ≥10 mg/L 1, 3
- For severe infections: ≥20 mg/L 1, 4
- Therapeutic drug monitoring is recommended in patients with rapidly changing renal function to guide dosing adjustments 1
Special Considerations for Renal Impairment
- Despite reduced dosing frequency, the per-dose amount should remain at 6-12 mg/kg to maintain efficacy 1, 5
- Patients with renal impairment have prolonged elimination half-lives (up to 163 hours in anuric patients compared to 41 hours in those with normal renal function) 6
- Volume of distribution is not significantly affected by renal impairment, so loading doses remain the same 6
Monitoring Recommendations
- Measure trough concentrations before the fourth dose (48-72 hours after initiation) 1, 5
- Monitor renal function regularly during treatment 1
- Consider more frequent monitoring in patients with oliguria as renal function may further deteriorate 1
Common Pitfalls to Avoid
- Inadequate loading doses leading to subtherapeutic levels early in treatment 1, 3
- Failure to extend dosing intervals in renal impairment leading to drug accumulation 1
- Not monitoring drug levels in high-risk situations (rapidly changing renal function) 1
- Using standard maintenance dosing intervals (24 hours) in patients with significant renal impairment 1, 6
