Hydroxocobalamin (Vitamin B12a)
Hydroxocobalamin is a man-made form of vitamin B12. Hydroxocobalamin is said to be one of the most promising antidotes available. The advantage using hydroxocobalamin is the lack of adverse effects seen with the nitrites such as methemoglobinemia and hypotension. It works by exchanging the hydroxy group for cyanide to form the non-toxic cyanocobalamin (vitamin B12).
Hydroxocobalamin is a vitamin used to treat or prevent low levels of Vitamin B12. It is used as a vitamin supplement to treat nerve damage, pernicious anemia, and the treatment and prevention of vitamin B-12 deficiencies in people who have had stomach or intestines surgically removed.
