Which antidote is used for cyanide poisoning in inhalation injuries?

Explanation:
Cyanide poisoning from inhalation injuries is treated by directly neutralizing the cyanide so cells can resume aerobic metabolism. Hydroxocobalamin does this by binding cyanide to form cyanocobalamin, which the body then eliminates in the urine. This direct scavenging works quickly and safely in smoke inhalation cases, making it the preferred antidote. The other agents don’t address cyanide: naloxone reverses opioid effects, atropine counters certain cholinergic toxicities, and calcium gluconate is used for calcium-related issues—none of which neutralize cyanide.
