Therapeutic Actions
Binds to alpha2-delta sites on the nerves in the CNS, which reduces the calcium influx into the cell and decreases the release of neurotransmitters into the synaptic cleft, resulting in less stimulation of the nerve; in lab studies, it also increases the transport and density of GABA, which is known to suppress nerve activity.
Indications
Management of acute pain associated with diabetic peripheral neuropathy
Management of post-herpetic neuralgia
Adjunct therapy of adult patients with partial onset seizures
Management of fibromyalgia
Management of neuropathic pain due to spinal cord injuries
