Overview
Gabenil 300mg Capsule contains gabapentin 300mg, an anticonvulsant also widely used to treat neuropathic (nerve) pain, such as post-herpetic neuralgia and diabetic nerve pain. It is used either as an add-on treatment for partial seizures or on its own for nerve pain conditions.
Gabapentin works by binding to calcium channels on overactive nerve cells, reducing the release of excitatory neurotransmitters. This calms down abnormal nerve signalling, which reduces both seizure activity and the sensation of nerve pain.
How it Works
Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system, reducing calcium influx into nerve terminals and decreasing the release of excitatory neurotransmitters such as glutamate. This dampens abnormal, overactive nerve signalling responsible for seizures and neuropathic pain.
Directions for Use
Take Gabenil 300mg Capsule with or without food, at evenly spaced intervals through the day as advised by your doctor. Swallow the capsule whole with water. Do not stop taking this medicine suddenly, as this can trigger withdrawal symptoms or, in epilepsy, increase the risk of seizures.
Dosage
Gabenil 300mg Capsule is usually started at a low dose and increased gradually over several days to the effective dose needed for your condition, typically given in 2-3 divided doses per day. Your doctor will individualise your dose and titration schedule, including a lower dose if you have reduced kidney function.
