๐Ÿ”ฌ Pharmacology (PK/PD)

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 ฮฑ2ฮด 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 ฮฑ2ฮด subunit of presynaptic voltage-gated calcium channels
2Reduces calcium influx into presynaptic terminals
3Decreases release of excitatory neurotransmitters (e.g., glutamate, substance P)
