Is Teicoplanin Removed During Hemodialysis?
No, teicoplanin is minimally removed by conventional hemodialysis, but high-flux membranes can remove clinically significant amounts (up to 20%), requiring dose adjustment.
Key Evidence on Dialyzability
The evidence shows conflicting results depending on the type of dialysis membrane used:
Conventional/Low-Flux Hemodialysis
- Teicoplanin is NOT significantly removed by standard hemodialysis 1, 2
- Less than 3% appears in dialysate with conventional membranes 2
- The drug's high molecular weight (1875-1891 daltons) and high protein binding (89%) prevent removal through standard membranes 3
High-Flux Hemodialysis
- Significant removal occurs with high-flux polysulfone membranes 3
- Extracorporeal clearance: 39.7 ± 24.5 mL/min with high-flux membranes 3
- 19.3% of the drug is removed during a single 3.5-hour high-flux dialysis session 3
- Levels drop from peak of 26.4 μg/mL to subtherapeutic 6.1 μg/mL by end of session 3
- With F60 high-flux filters, mean reduction is 20.2% per session versus only 9.1% with F8 filters 4
Clinical Implications & Dosing
Recommended Dosing Regimen for HD Patients
Based on guideline recommendations 1:
- Loading dose: 12 mg/kg
- Days 2 and 3: 6 mg/kg each day
- Maintenance: 6 mg/kg once weekly
Important Caveats
- Therapeutic drug monitoring is mandatory when using high-flux membranes 3
- Target trough concentrations: 10-20 mg/L for most infections, ≥20 mg/L for endocarditis or septic arthritis 1
- The terminal elimination half-life in HD patients is extremely prolonged (176 ± 41.3 hours) 4
- Dosing should occur after dialysis sessions to avoid immediate removal 5
Continuous Renal Replacement Therapy (CVVHD)
- Teicoplanin removal is significantly higher with CVVHD than intermittent HD 4
- Clearance increases with ultrafiltration rate: 32% removal at 15.6 L/24h versus 9.5% at 6.2 L/24h 4
- Dosing follows GFR 10-50 mL/min recommendations 1
Common Pitfalls to Avoid
- Assuming all HD is the same: High-flux membranes behave completely differently than conventional membranes—verify membrane type
- Timing of administration: Always give teicoplanin immediately after dialysis, not before
- Skipping TDM: The wide pharmacokinetic variability in dialysis patients makes monitoring essential, especially with high-flux membranes
- Underdosing: The prolonged half-life may tempt clinicians to extend intervals too far, risking subtherapeutic levels
Bottom line: While older data suggested teicoplanin was non-dialyzable, modern high-flux membranes remove clinically significant amounts. Always verify membrane type and implement therapeutic drug monitoring to ensure adequate levels.
