Antidotes are agents that counteract the effects of a toxic agent on the body.

Lipid Resuscitation: A Life-Saving Antidote for Local Anesthetic Toxicity

An antidote is a substance that can counteract a form of poisoning. Antidotes for anticoagulants are sometimes referred to as reversal agents. The antidotes for some particular toxins are manufactured by injecting the toxin into an animal in small doses and extracting the resulting antibodies from the host animals' blood. This results in an antivenom that can be used to counteract venom produced by certain species of snakes , spiders , and other venomous animals. Some animal venoms, especially those produced by arthropods such as certain spiders , scorpions , and bees are only potentially lethal when they provoke allergic reactions and induce anaphylactic shock ; as such, there is no "antidote" for these venoms; however anaphylactic shock can be treated e.

An antidote is a drug, chelating substance, or a chemical that counteracts neutralizes the effects of another drug or a poison. There are dozens of different antidotes; however, some may only counteract one particular drug, whereas others such as charcoal may help reduce the toxicity of numerous drugs. Some examples of antidotes include: Acetylcysteine for acetaminophen poisoning Activated charcoal for most poisons Atropine for organophosphates and carbamates Digoxin immune fab for digoxin toxicity Dimercaprol for arsenic, gold, or inorganic mercury poisoning Flumazenil for benzodiazepine overdose Methylene blue for drug-induced methemoglobinemia Naloxone for opioid overdose Pralidoxime for poisoning by anti-cholinesterase nerve agents.

Antidotes Summary

PAUL J. N -acetylcysteine is the acetylated variant of the amino acid L-cysteine and is widely used as the specific antidote for acetaminophen overdose. Other applications for N -acetylcysteine supplementation supported by scientific evidence include prevention of chronic obstructive pulmonary disease exacerbation, prevention of contrast-induced kidney damage during imaging procedures, attenuation of illness from the influenza virus when started before infection, treatment of pulmonary fibrosis, and treatment of infertility in patients with clomiphene-resistant polycystic ovary syndrome. Preliminary studies suggest that N -acetylcysteine may also have a role as a cancer chemopreventive, an adjunct in the eradication of Helicobacter pylori , and prophylaxis of gentamicin-induced hearing loss in patients on renal dialysis. Although N -acetylcysteine is widely known as an antidote to acetaminophen overdose, 1 it has multiple other uses supported by varying levels of evidence.

Antidotes are agents that negate the effect of a poison or toxin. Antidotes mediate its effect either by preventing the absorption of the toxin, by binding and neutralizing the poison, antagonizing its end-organ effect, or by inhibition of conversion of the toxin to more toxic metabolites. Antidote administration may not only result in the reduction of free or active toxin level, but also in the mitigation of end-organ effects of the toxin by mechanisms that include competitive inhibition, receptor blockade or direct antagonism of the toxin. Reduction in free toxin level can be achieved by specific and non-specific agents that bind to the toxin. The most commonly used non-specific binding agent is activated charcoal. Specific binders include chelating agents, bioscavenger therapy and immunotherapy.

Following an introductory chapter briefly discussing several important metal-related drugs and diseases and a chapter about drug development, the focus is fi rst on iron: its essentiality for pathogens and humans as well as its toxicity. Chelation therapy is addressed in the context of thalassemia, its relationship to neurodegenerative diseases and also the risks connected with iron administration are pointed out. A subject of intense debate is the essentiality of chromium and vanadium.

 Прости меня, - сказал он, стараясь говорить как можно мягче.  - Расскажи, что с тобой случилось. Сьюзан отвернулась. - Не имеет значения. Кровь не. Выпустите меня отсюда. - Ты ранена? - Стратмор положил руку ей на плечо.


Some antidotes, such as digoxin-specific antigen binding fragments. (digoxin immune Fab), are very expensive, and both the risk: benefit ratio and the associated.

Фонтейн смотрел в окно, пытаясь понять, что происходит. За несколько лет работы ТРАНСТЕКСТА ничего подобного не случалось. Перегрелся, подумал. Интересно, почему Стратмор его до сих пор не отключил. Ему понадобилось всего несколько мгновений, чтобы принять решение. Фонтейн схватил со стола заседаний трубку внутреннего телефона и набрал номер шифровалки. В трубке послышались короткие гудки.

Как весенний лед на реке, потрескивал корпус ТРАНСТЕКСТА. - Я спущусь вниз и отключу электропитание, - сказал Стратмор, положив руку на плечо Сьюзан и стараясь ее успокоить.  - И сразу же вернусь. Сьюзан безучастно смотрела, как он направился в шифровалку. Это был уже не тот раздавленный отчаянием человек, каким она видела его десять минут .

Я был уверен, что он тебе все рассказал.
