An antidote is a substance that can counteract a form of poisoning. [ 1 ] The term ultimately derives from the Greek term φάρμακον ἀντίδοτον (pharmakon antidoton), " (medicine) given as a remedy". Antidotes for anticoagulants are sometimes referred to as reversal agents. [ 2 ]
Cyanide is a potent cytochrome c oxidase (COX, a.k.a. Complex IV) inhibitor, causing asphyxiation of cells. As such, cyanide poisoning is a form of histotoxic hypoxia, because it interferes with the ability of cells to take or use oxygen via oxidative phosphorylation. [ 25 ]: 1475. Specifically, cyanide binds to the heme a3-CuB binuclear center ...
The CcdA/CcdB Type II Toxin-antitoxin system is one example of the bacterial toxin-antitoxin (TA) systems that encode two proteins, one a potent inhibitor of cell proliferation (toxin) and the other its specific antidote (antitoxin). These systems preferentially guarantee growth of plasmid -carrying daughter cells in a bacterial population by ...
The primary antidote to brodifacoum poisoning is immediate administration of vitamin K 1 (dosage for humans: initially slow intravenous injections of 10–25 mg repeated at 3–6 hours until normalisation of the prothrombin time; then 10 mg orally four times daily as a "maintenance dose"). It is an extremely effective antidote, provided the ...
Strychnos toxifera, the Strychnos species which is the principal source of 'calabash curare' and its main active constituent, the alkaloid toxiferine. Curare (/ kʊˈrɑːri / or / kjʊˈrɑːri /; kuu-RAH-ree or kyuu-RAH-ree) is a common name for various alkaloid arrow poisons originating from plant extracts.
Pralidoxime. Pralidoxime (2-pyridine aldoxime methyl chloride) or 2-PAM, usually as the chloride or iodide salts, belongs to a family of compounds called oximes that bind to organophosphate -inactivated acetylcholinesterase. [ 1 ] It is used to treat organophosphate poisoning [ 2 ] in conjunction with atropine and either diazepam or midazolam ...
v. t. e. A blood agent is a toxic chemical agent that affects the body by being absorbed into the blood. [ 1 ] Blood agents are fast-acting, potentially lethal poisons that typically manifest at room temperature as volatile colorless gases with a faint odor. [ 1 ] They are either cyanide - or arsenic -based.
Batrachotoxin (BTX) is an extremely potent cardiotoxic and neurotoxic steroidal alkaloid found in certain species of beetles, birds, and frogs. The name is from the Greek word βάτραχος, bátrachos, 'frog'. [ 3 ] Structurally-related chemical compounds are often referred to collectively as batrachotoxins.
