CLINICAL PHARMACOLOGY
MECHANISM OF ACTION
The mechanism by which gabapentin exerts its analgesic action is
unknown, but in animal models of
analgesia, gabapentin prevents allodynia (pain-related behavior in
response to a normally innocuous
stimulus) and hyperalgesia (exaggerated response to painful stimuli).
In particular, gabapentin prevents
pain-related responses in several models of neuropathic pain in rats
or mice (e.g. spinal nerve ligation
models, streptozocin-induced diabetes model, spinal cord injury model,
acute herpes zoster infection
model). Gabapentin also decreases pain-related responses after
peripheral inflammation (carrageenan
footpad test, late phase of formalin test). Gabapentin did not alter
immediate pain-related behaviors (rat
tail flick test, formalin footpad acute phase, acetic acid abdominal
constriction test, footpad heat
irradiation test). The relevance of these models to human pain is not
known.
