Sodium Thiosulfate is indicated for sequential use with sodium nitrite for treatment of acute cyanide poisoning that is judged to be life threatening. Use with caution if the diagnosis of cyanide poisoning is uncertain.
Composition
ফার্মাকোলজি
Sodium thiosulfate acts as an antidote in the treatment of cyanide poisoning. It acts as a sulphur-donating substrate for the enzyme rhodanese, thus speeding up the conversion of cyanide to thiocyanide, which is relatively non toxic. It is often used in combination with sodium nitrite but may be used alone in less severe poisoning.
মাত্রা ও সেবনবিধি
Adult: To be given after 300 mg of sodium nitrite has been admin over 5-20 min: 12.5 g of sodium thiosulfate (50 ml of a 25% solution or 25 ml of a 50% solution) given over 10 min. Methaemoglobin concentration should not exceed 30-40%. If symptoms of cyanide toxicity recur, the doses of nitrite and thiosulfate may be repeated after 30 min at half the initial doses. Child: To be given after 4-10 mg/kg of sodium nitrite (max: 300 mg) has been admin: 400 mg/kg of sodium thiosulfate, as a 25 or 50% solution (max: 12.5 g). Methaemoglobin concentration should not exceed 30-40%. If symptoms of cyanide toxicity recur, the doses of nitrite and thiosulfate may be repeated after 30 min at half the initial doses.

গর্ভাবস্থায় ও স্তন্যদানকালে
Pregnancy Category C. There are no adequate and well controlled studies in pregnant women. Sodium Thiosulfate Injection should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether sodium thiosulfate is excreted in human milk. Because Sodium Thiosulfate Injection may be administered in life-threatening situations, breast-feeding is not a contraindication to its use. Because many drugs are excreted in human milk, caution should be exercised following Sodium Thiosulfate Injection administration to a nursing woman. There are no data to determine when breastfeeding may be safely restarted following administration of sodium thiosulfate.
সতর্কতা
Sodium thiosulfate drug product may contain trace impurities of sodium sulfite. The presence of a trace amount of sulfites in this product should not deter administration of the drug for treatment of emergency situations, even if the patient is sulfite-sensitive.
