🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionGabapentin is absorbed via L-amino acid transporter; absorption is saturable and dose-dependent. Methylcobalamin is absorbed in the small intestine.
DistributionGabapentin distributes widely, crosses blood-brain barrier. Methylcobalamin distributes to tissues, stored in liver.
Protein BindingGabapentin: <3% bound. Methylcobalamin: highly bound to transcobalamins.
MetabolismGabapentin: negligible hepatic metabolism. Methylcobalamin: converted to other cobalamins in tissues.
Half-LifeGabapentin: 5-7 hours. Methylcobalamin: approximately 6 days (plasma).
ExcretionGabapentin: renal (unchanged). Methylcobalamin: biliary and renal.
BioavailabilityGabapentin: ~60% (dose-dependent, decreases with higher doses). Methylcobalamin: variable, oral ~50%
Onset of ActionGabapentin: 1-2 hours. Methylcobalamin: days to weeks.
Peak Plasma TimeGabapentin: 2-3 hours. Methylcobalamin: 8-12 hours.
Duration of ActionGabapentin: 6-8 hours. Methylcobalamin: prolonged.

How It Works

Gabapentin binds to α2δ subunit of voltage-gated calcium channels, reducing calcium influx and neurotransmitter release. Methylcobalamin acts as a cofactor for methionine synthase and methylmalonyl-CoA mutase, promoting myelin synthesis and nerve regeneration.

Mechanism Steps

1Gabapentin binds to α2δ subunit of presynaptic voltage-gated calcium channels
2Reduces calcium influx into presynaptic terminals
3Decreases release of excitatory neurotransmitters (e.g., glutamate, substance P)
4Modulates neuronal excitability and pain transmission
5Methylcobalamin is converted to adenosylcobalamin and methylcobalamin
6Acts as cofactor for methionine synthase (myelination) and methylmalonyl-CoA mutase (fatty acid metabolism)
7Promotes synthesis of myelin and nerve regeneration
