Methylcobalamin, vitamin B12 preparations containing benzyl alcohol should be avoided in premature neonates because benzyl alcohol has been associated with gasping syndrome, a potentially fatal condition characterized by metabolic acidosis and CNS, respiratory, circulatory, and renal dysfunction
It binds to transport proteins, primarily transcobalamin II , which delivers B12 to tissues throughout the body
Weight reduction in obese subjects causes a substantial increase and normalization of sensitivity to catecholamine stimulation of lipolysis (77) without changing the number of -adrenergic receptors (102)
