💉 Sodium Thiosulphate Injection 250 mg/mL
📌 Description:
Sodium thiosulphate injection is a sterile intravenous solution primarily used as part of cyanide poisoning treatment. It serves as a sulfur donor, enhancing the conversion of cyanide to the less toxic thiocyanate, which is then excreted in the urine.
