Therapeutic Drug Monitoring (TDM) Targets
Drug
When to use
Look up the target range and when to sample (trough/peak/steady state). Interpret levels with clinical efficacy and toxicity.
How it works
Examples: digoxin 0.5–2.0 ng/mL (HF 0.5–0.9); phenytoin total 10–20 µg/mL; lithium 0.6–1.0 mmol/L; vancomycin AUC/MIC 400–600.
Key points
- Units and assays vary between laboratories.
- Wrong sampling timing (before steady state, not a true trough/peak) causes misinterpretation.
- A subtherapeutic level with good clinical response need not be changed.
- For vancomycin and aminoglycosides see the dedicated dosing tools.
