Hydroxocobalamin is a synthetic form of vitamin B12, which acts as a cofactor for methionine synthase and methylmalonyl-CoA mutase, essential for DNA synthesis, myelin formation, and hematopoiesis.
Hydroxocobalamin is a synthetic form of vitamin B12 that acts as a cofactor for methionine synthase and methylmalonyl-CoA mutase, essential for DNA synthesis, myelin formation, and hematopoiesis. It also binds to cyanide ions to form cyanocobalamin, which is excreted renally, thereby detoxifying cyanide.
1 mg intramuscularly once every 7-10 days for maintenance; 1 mg intramuscularly once daily for 7 days for initial treatment.
Cyanocobalamin 1000 mcg intramuscularly or subcutaneously once daily for 5-10 days, then 100-1000 mcg monthly for maintenance; intranasal: 500 mcg intranasally once weekly.

Terminal elimination half-life is approximately 6 days (range 4-10 days) in plasma; however, due to extensive tissue binding and enterohepatic recirculation, the pharmacodynamic half-life for correction of deficiency is about 1 year.
~50-100 minutes; prolonged in renal impairment
Primarily renal: ~50-80% of absorbed dose excreted unchanged in urine via glomerular filtration. Biliary/fecal excretion accounts for <10% as cyanocobalamin.
Primarily renal (50-80% as unchanged drug); minimal biliary/fecal
