			{{Use dmy dates\|date=October 2023}}

	Toxication, also known as ~~poisoning,~~ is ~~the condition that occurs when an individual is exposed to~~ a ~~harmful substance~~, ~~known~~ as ~~a toxin, in quantities that exceed the body's ability~~ to ~~detoxify or eliminate it. Toxication can result from various sources, including ingesting, inhaling, or coming into contact with toxic~~ substances~~. The severity of toxication~~ can ~~range from mild discomfort~~ to ~~life-threatening situations, depending on~~ the ~~type and amount of toxin involved~~.		'''Toxication''' is the process by which a chemical compound becomes more toxic after undergoing metabolic transformation. This process is also known as metabolic activation. Toxication is a critical concept in [[toxicology]] and [[pharmacology]], as it helps to understand how certain substances can become harmful to the body.

	~~Symptoms of toxication can vary widely depending on~~ the ~~specific toxin involved, but common signs may include nausea, vomiting, diarrhea~~, ~~dizziness, confusion, difficulty breathing, and~~ in ~~severe cases, seizures or loss~~ of ~~consciousness. It is~~ important ~~to seek immediate medical attention if~~ toxication is ~~suspected~~, ~~as prompt treatment can be crucial in preventing serious complications~~.		==Mechanism==
			Toxication occurs when a non-toxic or less toxic substance is metabolized by the body into a more toxic form. This transformation is often mediated by [[enzyme]]s, particularly those in the [[cytochrome P450]] family. One of the most important enzymes involved in toxication is [[CYP3A4]], which is responsible for the metabolism of many drugs and endogenous compounds.

	~~Treatment for toxication typically involves removing~~ the ~~individual from further exposure to the toxin, providing supportive care such as intravenous fluids or medications to counteract the effects~~ of ~~the toxin, and in some cases, administering specific antidotes if available. In severe cases, procedures such as gastric lavage or activated charcoal may be used to help remove the toxin from the body~~.		[[File:CYP3A4.png\|thumb\|right\|CYP3A4 is a key enzyme in the metabolism of many substances.]]

	Preventing toxication is key to reducing the risk of harm from toxic substances. This can be achieved through proper storage and handling of chemicals, medications, and household products, as well as following safety guidelines when working with potentially hazardous materials. Education on the dangers of toxic substances and how to respond in case of exposure is also important in preventing toxication incidents.		==Examples==

	~~For more information on specific toxins and their effects on the body, please refer to the following articles:~~		===Methanol===
	* [[~~poisoning~~]]		[[Methanol]] is a type of alcohol that is not highly toxic in its original form. However, when ingested, it is metabolized by the enzyme [[alcohol dehydrogenase]] into formaldehyde, which is then further oxidized to formic acid. Both formaldehyde and formic acid are highly toxic, leading to metabolic acidosis, visual disturbances, and potentially death.

	* [[drug overdose]]
	* [[food poisoning]]

	~~Category~~:Toxicology
	Category:~~Emergency medicine~~		===Ethylene Glycol===
	~~{{medicine-stub}}~~		[[Ethylene glycol]], commonly found in antifreeze, is another example of a substance that becomes more toxic after metabolism. It is metabolized by alcohol dehydrogenase to glycolaldehyde, which is further metabolized to glycolic acid, glyoxylic acid, and finally oxalic acid. These metabolites can cause severe metabolic acidosis and renal failure.

			==Prevention and Treatment==
			Preventing toxication involves avoiding exposure to the parent compound or inhibiting the metabolic pathway that leads to the formation of toxic metabolites. For example, [[fomepizole]] and [[ethanol]] are used as antidotes for methanol and ethylene glycol poisoning because they inhibit alcohol dehydrogenase, preventing the formation of toxic metabolites.

Toxication

Toxication, also known as poisoning, is the condition that occurs when an individual is exposed to a harmful substance, known as a toxin, in quantities that exceed the body's ability to detoxify or eliminate it. Toxication can result from various sources, including ingesting, inhaling, or coming into contact with toxic substances. The severity of toxication can range from mild discomfort to life-threatening situations, depending on the type and amount of toxin involved.

Symptoms of toxication can vary widely depending on the specific toxin involved, but common signs may include nausea, vomiting, diarrhea, dizziness, confusion, difficulty breathing, and in severe cases, seizures or loss of consciousness. It is important to seek immediate medical attention if toxication is suspected, as prompt treatment can be crucial in preventing serious complications.

Treatment for toxication typically involves removing the individual from further exposure to the toxin, providing supportive care such as intravenous fluids or medications to counteract the effects of the toxin, and in some cases, administering specific antidotes if available. In severe cases, procedures such as gastric lavage or activated charcoal may be used to help remove the toxin from the body.

Preventing toxication is key to reducing the risk of harm from toxic substances. This can be achieved through proper storage and handling of chemicals, medications, and household products, as well as following safety guidelines when working with potentially hazardous materials. Education on the dangers of toxic substances and how to respond in case of exposure is also important in preventing toxication incidents.
