Summary
New daily hemodialysis techniques may alter drug clearance in chronic kidney disease patients. This review examines how these enhanced renal replacement therapies impact drug removal and dosing strategies.
Area of Science:
- Nephrology
- Clinical Pharmacology
Background:
- Standard hemodialysis (3 times/week) is established for chronic kidney disease (CKD).
- Short-daily and nocturnal hemodialysis (6-7 times/week) offer potential benefits for CKD complications.
- These daily regimens enhance solute clearance and extracellular volume management.
Purpose of the Study:
- To review drug removal concepts in hemodialysis.
- To discuss the impact of new daily hemodialysis techniques on drug clearance.
- To inform the design of drug dosing regimens for patients on daily hemodialysis.
Main Methods:
- Literature review of hemodialysis techniques and drug removal principles.
- Analysis of solute clearance and extracellular volume management in daily hemodialysis.
- Discussion of implications for drug pharmacokinetics and dosing.
Main Results:
- Daily hemodialysis regimens significantly increase solute clearance compared to conventional therapy.
- Improved extracellular fluid management is a key benefit of frequent hemodialysis.
- Altered dialysate drug clearance is anticipated with daily hemodialysis protocols.
Conclusions:
- Daily hemodialysis necessitates re-evaluation of drug dosing strategies.
- Enhanced drug removal by frequent hemodialysis may require dose adjustments.
- Further research is needed to optimize pharmacotherapy in patients undergoing daily hemodialysis.

01:25Drug Dosing in Renal Diseases: Dose Adjustments Based on Drug Clearance and Elimination Rate Constant
In patients with renal disease, dosage adjustments are necessary to maintain therapeutic plasma drug concentrations and prevent toxicity or subtherapeutic exposure. Renal impairment alters drug pharmacokinetics, especially in conditions like uremia, where changes such as prolonged elimination half-life and altered apparent volume of distribution can significantly affect drug disposition. These changes require careful modification of the dosing regimen to achieve the desired clinical...
01:11Renal Failure: Dose Adjustments
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
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.

01:30Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis
Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...
01:24Hemodialysis II: Procedure and Complications
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
01:25Hemodialysis III: Nursing Management
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this measurement...
01:28Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration
Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...
