All Services Pharmacotherapy Optimisation

Therapeutic Drug Monitoring.

Measurement of medication levels in blood to optimise dosing, reduce toxicity, and enhance treatment efficacy — essential for drugs with narrow therapeutic indices.

Why TDM Matters
Efficacy Ensure drug concentrations remain within the therapeutic window
Safety Prevent toxicity from medications with narrow therapeutic indices
Individual Account for pharmacokinetic variability between patients
Compliance Verify patient adherence to prescribed medication regimens

Monitoring Principles.

Narrow Therapeutic Index Critical for drugs where small dose changes cause significant efficacy or toxicity shifts
Non-Linear Kinetics Essential when drug metabolism does not follow proportional dose-response relationships
Inter-Individual Variability Accounts for genetic, age, and organ function differences affecting drug levels
Polypharmacy Monitors drug interactions when patients take multiple medications simultaneously
