Summary
Hemoadsorption (HA) therapies may unintentionally remove drugs, impacting critically ill patients. Further research is needed to establish drug dosing guidelines and confirm HA
Area of Science:
- Critical Care Medicine
- Pharmacology
- Biomedical Engineering
Background:
- Growing interest in hemoadsorption (HA) for critically ill patients.
- Uncertainty regarding specific indications for HA therapies.
- Heterogeneous properties and capabilities of available HA devices.
Purpose of the Study:
- To review the influence of various HA techniques on drug pharmacokinetics.
- To address concerns about unintended drug removal by HA.
- To explore potential benefits of drug removal by HA in specific clinical scenarios.
Main Methods:
- In vitro studies.
- In vivo studies.
- Clinical studies.
Main Results:
- Nonspecific drug removal by most HA techniques is a concern.
- Potential for beneficial drug removal in cases of intoxication or emergency surgery.
- Varied effects of HA on drug pharmacokinetics reported across studies.
Conclusions:
- Further studies are required to provide drug dosing recommendations during HA.
- Need to confirm the safety, efficacy, and practicalities of HA for intoxications.
- HA's impact on drug pharmacokinetics requires careful consideration in clinical practice.

01:22Drug Elimination by Renal Route: Tubular Reabsorption
4.6K
During the process of renal excretion, as the glomerular filtrate progresses to the distal convoluted tubule (DCT), drugs that are highly permeable, lipophilic, and nonionized undergo passive reabsorption from the tubular fluid into the surrounding peritubular capillaries. This reabsorption process restricts their elimination through the kidneys. However, the majority of drugs are either weak acids or weak bases, and their ionization level is dependent on pH. By altering the pH of urine, the...

01:23Drug Elimination: Non-Renal Routes
3.1K
The liver plays a pivotal role in eliminating drugs and their metabolites, primarily through a process known as biliary excretion. This process involves the hepatocytes, the primary cells in the liver that generate bile. A range of transporters actively expels polar drugs or hydrophilic drug metabolites into the bile, which transports the drugs and metabolites into the small intestine. From here, they are eventually expelled from the body through feces. In some instances, the original drug or a...

Poison can be effectively removed from the gastrointestinal (GI) tract through various decontamination procedures.
Antidotes serve a crucial role in counteracting the effects of poison by inhibiting enzymes responsible for producing harmful drug metabolites. In some cases, these toxic metabolites can be neutralized by endogenous cosubstrates, which are maintained at specific concentrations to prevent interaction with cellular macromolecules and subsequent cell death.

1.1K
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...

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...
