๐Ÿ”ฌ Pharmacology (PK/PD)

Pharmacokinetics

AbsorptionRapidly absorbed after intramuscular injection; bioavailability is high due to direct entry into systemic circulation.
DistributionWidely distributed in body tissues, including the central nervous system; crosses the placenta and enters breast milk.
Protein BindingApproximately 90% bound to plasma proteins, mainly transcobalamins.
MetabolismMetabolized in the liver via conversion to other cobalamin forms (e.g., adenosylcobalamin) and coenzymes.
Half-LifeApproximately 6 days (400 hours) in the body; hepatic stores can last for years.
ExcretionPrimarily excreted in bile; small amount in urine; enterohepatic circulation occurs.
Bioavailability100% (intramuscular injection); oral bioavailability is low (<3%) due to need for intrinsic factor.
Onset of ActionWithin 24-48 hours for hematological effects; neurological improvement may take weeks to months.
Peak Plasma Time1-2 hours after intramuscular injection.
Duration of ActionEffects last for several days to weeks depending on the condition treated.

How It Works

Methylcobalamin acts as a cofactor for methionine synthase, converting homocysteine to methionine, and for methylmalonyl-CoA mutase, converting methylmalonyl-CoA to succinyl-CoA, essential for DNA synthesis, myelin formation, and red blood cell production.

Mechanism Steps

1Methylcobalamin binds to intrinsic factor in the stomach for absorption (oral) or directly enters circulation (injection).
2Transported in blood bound to transcobalamin II.
3Enters cells via receptor-mediated endocytosis.
