Regitine produces an alpha-adrenergic block of relatively short duration. Oxidizes hemoglobin to methemoglobin which binds the free cyanide and can enhance endothelial cyanide detoxification by producing vasodilation.Ĭopper, gold, lead, mercury, zinc, arsenic Naloxone is believed to antagonize opioid effects by competing for the µ, κ and σ opiate receptor sites in the CNS, with the greatest affinity for the µ receptor.Īnticholinesterase which causes accumulation of acetylcholine at cholinergic receptor sites. Prevents or reverses the effects of opioids including respiratory depression, sedation and hypotension. Protects the healthy cells from the effects of methotrexate while allowing methotrexate to enter and kill cancer cells.Ī “chemoprotectant” drug that reduces the undesired effects of certain chemotherapy drugs.Ĭhemical producing severe methemoglobinemia. Used in combination with vasodilator phentolamine or nitroprusside to prevent local thrombosis and ischemia.įorms cyanocobalamin, a non-toxic metabolite that is easily excreted through the kidneys. Reverses hypercoagulable state by interacting with antithrombin III. Stimulates the formation of adenyl cyclase causing intracellular increase in cycling AMP and enhanced glycogenolysis and elevated serum glucose concentration.ĭextrose (the monosaccharide glucose) is used, distributed and stored by body tissues and is metabolized to carbon dioxide and water with the release of energy. This enzyme plays a key role in the metabolism of ethylene glycol and methanol.īeta blockers and calcium channel blockers Reverses the effects of benzodiazepines by competitive inhibition at the benzodiazepine binding site on the GABA A receptor.Ī competitive inhibitor of the enzyme alcohol dehydrogenase found in the liver. Not known partial protection against acute hepatic failure may displace amatoxin from protein-binding sites allowing increased renal excretion may also inhibit penetration of amatoxin to hepatocytes.ĭeferoxamine acts by binding free iron in the bloodstream and enhancing its elimination in the urine.īinds molecules of digoxin, making them unavailable for binding at their site of action on cells in the body.Ĭhelation of lead ions and endogenous metals (e.g., zinc, manganese, iron, copper).Ī potent antagonist to acetylcholine in muscarinic receptors. Interrupts the entero-hepatic cycle with multiple dose.Īlbuterol inhaler, insulin & glucose, NaHCO 3, kayexalateĬompetitive inhibition of muscarinic receptors. Non-specific poisons except cyanide, iron, lithium, caustics and alcohol.Ībsorption of drug in the gastric and intestinal tracts. Restores depleted glutathione stores and protects against renal and hepatic failure. The following are antidotes that should be familiarized by the nurse to respond to this emergency situation quickly. This post will help you familiarize yourself with the common antidotes that are used in the hospital setting. The term antidote is a Greek word meaning “given against”. This review explores the various uses of n-acetylcysteine in the field of dermatology, the evidence supporting the same, the possible mechanisms of action and the adverse effects of the drug.Īntioxidant drug reaction n-acetylcysteine trichotillomania.An antidote is a substance that can counteract a form of poisoning. Thus a greater role is possible for use of n-acetylcysteine in various skin conditions. The drug is cheap and is generally safe with few adverse effects. Higher quality of evidence is needed for its wider use. Most indications in dermatology are supported by case reports, small case series and small trials. It also has a role in protection from radiation-induced skin damage including photo-ageing, photocarcinogenesis and radiation dermatitis. The drug has been used as an adjuvant in the management of conditions such as toxic epidermal necrolysis, drug hypersensitivity syndrome, trichotillomania, skin picking disorders and onychotillomania, ichthyoses, contact dermatitis, atopic dermatitis, melasma, pseudoporphyria, connective tissue diseases, wound healing and alopecia. Due to these actions, n-acetylcysteine has found use in several dermatologic conditions in systemic and topical form. It also has anti-inflammatory effects, alters the levels of neurotransmitters, inhibits proliferation of fibroblasts and keratinocytes and causes vasodilatation. It is a thiol compound, which acts as a donor of cysteine, leading to replenishment of glutathione and thus acts as an antioxidant. N-acetylcysteine is a mucolytic drug which is commonly used as an antidote for acetaminophen toxicity.
