Therapeutic plasma exchange (TPE) removes substances from blood plasma. This review examines TPE
Area of Science:
- Neurology
- Pharmacology
- Nephrology
Background:
- Therapeutic plasma exchange (TPE) is an extracorporeal procedure that removes plasma from blood.
- TPE is increasingly used in neurocritical care for autoimmune neurological disorders.
- TPE can unintentionally remove medications from circulation.
Purpose of the Study:
- To review current evidence on drug removal during TPE.
- To offer clinical guidance for managing drug removal by TPE.
- To develop a tool for predicting drug removal potential.
Main Methods:
- Literature review of studies on TPE and drug removal.
- Analysis of pharmacokinetic and procedure-specific factors influencing drug removal.
- Synthesis of clinical data and expert opinion.
Main Results:
- Drug removal by TPE varies significantly based on drug properties and TPE parameters.
- Certain drugs are highly susceptible to removal, necessitating dose adjustments.
- TPE can impact the efficacy of essential medications.
Conclusions:
- Understanding drug removal during TPE is crucial for patient safety and treatment efficacy.
- Clinical guidelines are needed to manage drug therapy during TPE.
- Predictive tools can aid clinicians in optimizing medication regimens during TPE.

Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis
Determination of Multiple Dosing Parameters: Loading and Maintenance Doses

Determination of Multiple Dosing Parameters: Steady-State, Minimum and Maximum Concentrations
Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
