How Gpentin works
Gpentin is an antiepileptic medication. When given for epilepsy, it is believed to work by reducing the abnormal electrical activity in the brain, thus preventing seizures. It is also used to treat nerve pain where it blocks pain by interfering with pain signals travelling through the damaged nerves and the brain.
What if you forget to take Gpentin?
If you miss a dose of Gpentin, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
Quick Tips
- Take it at the same time every day, preferably at bedtime, to avoid any dizziness or drowsiness during the day.
- Avoid taking antacids 2 hours before or after taking Gpentin as they make it harder for your body to absorb the medicine.
- It may cause sleepiness. Do not drive or do anything requiring concentration until you know how it affects you.
- Inform your doctor if you develop any unusual changes in mood or behavior, new or worsening depression, or suicidal thoughts or behavior.
- Do not stop taking Gpentin suddenly without talking to your doctor as it may increase the frequency of seizure.

Partial Seizures
Adjunctive therapy for partial seizures with or without secondary generalization in patients older than 12 years of age with epilepsy; also indicated as adjunctive therapy for partial seizures in pediatric patients aged 3-12 years
12 years (initial dose): 300 mg PO q8hr; may increase up to 600 mg PO q8hr
Renal Dose
Renal impairment
CrCl >60 mL/min: 300-1200 mg PO TID
CrCl 30-60 mL/min: 200-700 mg q12hr
CrCl 15-29 mL/min: 200-700 mg qDay
CrCl <15 mL/min: 100-300 mg qDay
Hemodialysis (CrCl <15 mL/min): Administer supplemental dose (range 125-350 mg) posthemodialysis, after each 4 hr dialysis interval; further dose reduction should be in proportion to CrCl (eg, CrCl of 7.5 mL/min should receive one-half daily posthemodialysis dose)
Contraindication
Hypersensitivity. Lactation.
Mode of Action
Gabapentin is structurally related to the neurotransmitter GABA but is neither a GABA agonist nor antagonist. High affinity gabapentin binding sites are located throughout the brain. These sites correspond to the presence of voltage-gated Ca channels particularly controlling the ?-2/?-1 subunit. This channel appears to be located presynaptically and may modulate the release of excitatory neurotransmitters which participate in epileptogenesis and nociception.
Precaution
Discontinuation or transfer from other antiepileptics, history of psychotic illness; renal impairment; pregnancy. Gradual withdrawal over at least 7 days to prevent an increase in seizure frequency.
Lactation: Enters breast milk; use with caution
