Introduction

Gabapentin 100mg is a widely used medication for the treatment of neuropathic pain and other nerve-related conditions. Originally developed as an anticonvulsant, it has gained prominence for its effectiveness in managing chronic pain conditions such as diabetic neuropathy, postherpetic neuralgia, and restless leg syndrome. This article explores the benefits, uses, dosage, side effects, and other essential information about Gabapentin 100mg and 400mg tablets.

What is Gabapentin?

Gabapentin 400mg is an antiepileptic drug that affects the nervous system by modulating calcium channels in nerve cells. This modulation reduces abnormal nerve activity, which helps alleviate pain and seizures. It is commonly prescribed for conditions that involve nerve damage and chronic pain syndromes.

How Gabapentin Works

Gabapentin 100mg primarily affects the nervous system by altering the way nerves transmit pain signals to the brain. Although its exact mechanism of action is not fully understood, it is believed to reduce nerve excitability and stabilize electrical activity in the brain, making it effective for both epilepsy and neuropathic pain.
