Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Pharmaceutical Poisoning: Treatment Strategies

Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...
Enhanced Elimination of Poison01:26

Enhanced Elimination of Poison

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.
Renal excretion is the...
Antidotes01:17

Antidotes

Antidotes are medicinal substances used to counteract the harmful effects of toxins or drugs in the body. They function in various ways, each uniquely designed to combat specific toxic compounds.
Specific antidotes operate by inhibiting the enzymes that control biochemical pathways, reducing the production of harmful metabolites.
An example of an antidote is atropine, which counteracts the detrimental effects of cholinesterase inhibitors. It achieves this by deactivating muscarinic receptors,...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

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...
Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis01:30

Extracorporeal 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...

Area of Science:

  • Toxicology
  • Materials Science

Background:

  • Aspirin overdose can cause severe symptoms like vomiting, pulmonary edema, and dyspnea.
  • Current treatments such as stomach lavage, emetics, and activated charcoal have limited efficacy.

Purpose of the Study:

  • To develop and evaluate an active emulsion for treating aspirin intoxication.

Main Methods:

  • An emulsion was formulated using dodecane as the oil phase, 8% Abil EM90 as the surfactant, and 0.1 mol/L sodium hydroxide as the inner aqueous phase.
  • The volume ratio of the internal aqueous phase to the oil phase was maintained at 2:1.

Main Results:

  • The developed active emulsion demonstrated a 100% detoxifying efficiency against aspirin intoxication.
  • Complete detoxification was achieved in less than 15 minutes.

Conclusions:

  • The novel active emulsion presents a highly efficient and rapid treatment strategy for aspirin intoxication.
  • This formulation significantly outperforms existing methods in terms of speed and efficacy.
