Sodium thiosulfate and sodium nitrite in combination are used via injection to treat the effects of cyanide poisoning. Poisoning with cyanide is an extremely serious condition that can be fatal in many cases and as such always necessitates immediate attention.
Cyanide poisoning typically results from exposure to toxic compounds that contain cyanide. These chemicals can be contained in some materials that are used in the manufacturer of household furnishings. This is why cyanide poisoning occurs commonly in people who have inhaled smoke during a house fire. Certain insecticides are also known to contain cyanide, as do some metal polishes, and the seeds of some fruits such as cherries, apples, and apricots.
Cyanide in liquids can be absorbed through the skin. It can be ingested in food or inhaled in gaseous form via smoke. The toxin interferes with the body’s cellular respiration, which results in the tissues being unable to use the oxygen.
Sodium thiosulfate and sodium nitrite combination injection works by reacting with the hemoglobin that is contained in the patient’s blood to form methemoglobin. The methemoglobin acts like a magnet to the cyanide, binding with it and effectively preventing it from stripping oxygen from the red blood cells. In addition, sodium thiosulfate converts the cyanide molecules into thiocyanate, which is much less toxic to the body. The thiocyanate is more easily and readily excreted in the patient’s urine, speeding the removal of the toxin from the body.
