![]() The charcoal is "activated" because it is produced to have a very fine particle size.It will only attach to substances that are still inside the stomach or intestines. ![]() Once the chemical or drug has been absorbed by the GI tract, activated charcoal can no longer retrieve the toxic ingestion. Absorption occurs when a substance passes into or through a tissue, like water passing into a sponge. This mechanism of action should not be confused with absorption.Because charcoal is not "digested," it stays inside the GI tract and eliminates the toxin when the person has a bowel movement. In other words, the toxic substance attaches to the surface of the charcoal. Adsorption is a process in which atoms and molecules move from a bulk phase (such as a solid, liquid, or gas) onto a solid or liquid surface. Gastric lavage is only effective immediately after swallowing a toxic substance (within about one-half hour) and does not have effects that reach beyond the stomach as activated charcoal does.Īctivated charcoal absorbs a wide variety of drugs and chemicals. Activated charcoal is often given after the stomach is pumped (gastric lavage).Activated charcoal itself is a fine, black powder that is odorless, tasteless, and nontoxic.It works by binding (adsorbing) chemicals, thus reducing their toxicity (poisonous nature), through the entire length of the stomach and small and large intestines (GI tract).Activated charcoal is estimated to reduce absorption of poisonous substances nearly to 60%. ![]() It is used after a person swallows or absorbs almost any toxic drug or chemical. Activated charcoal is considered to be the most effective single agent available. That's how powerful activated charcoal is as an emergency decontaminant in the gastrointestinal (GI) tract, which includes the stomach and intestines. He had combined the deadly poison with activated charcoal. ![]() ![]() In front of his distinguished colleagues at the French Academy of Medicine, Professor Touery drank a lethal dose of strychnine and lived to tell the tale. ![]()
