Indications & Uses

Epipen is indicated for:

Pharmacology

Gabapentin belongs to the anti-convulsant class of medicines and is structurally similar to gamma-amino-butyric acid (GABA), though its effects come entirely from the parent compound itself rather than any breakdown product. It works by attaching to the alpha-2-delta subunit of voltage-gated L-type calcium channels, which in turn blocks branched-chain amino acid transferase and is thought to reduce the release of excitatory neurotransmitters.
