Mechanism and action
Coumadin: Warfarin inhibits vitamin K epoxide reductase complex 1 (VKORC1), the enzyme responsible for regenerating reduced vitamin K, a cofactor for the gamma-carboxylation of clotting factors. Neurontin: Gabapentin binds the alpha-2-delta auxiliary subunit of voltage-gated calcium channels in the central nervous system, reducing presynaptic calcium influx and the release of excitatory neurotransmitters such as glutamate…
