What is the authorized treatment for cyanide poisoning?

Hydroxocobalamin is the authorized treatment for cyanide poisoning because it actively binds to cyanide, forming a non-toxic complex that can be excreted by the kidneys. This mechanism helps to quickly reduce the levels of free cyanide in the body, mitigating its toxic effects, which can be life-threatening. Hydroxocobalamin is preferred in emergency situations due to its effectiveness and safety profile when used in the appropriate dosage.

Sodium thiosulfate can be used as an adjunct therapy in treating cyanide poisoning, but it typically aids in the conversion of cyanide to thiocyanate, which is less toxic and is excreted in urine. However, it doesn't have the same rapid action or direct antidotal effect as hydroxocobalamin.

Nitroprusside is actually associated with cyanide toxicity since it can metabolize to cyanide when given in high doses or for prolonged periods, leading to a risk of cyanide poisoning rather than being a treatment for it.

Aspirin is not related to cyanide poisoning treatment and is not effective against this type of toxicity. It serves entirely different therapeutic purposes and does not address the mechanism of cyanide poisoning.

In summary, hydroxocobalamin stands out as the
