Gabapentin 100 Mg Capsule

Gabapentin 100 mg capsules are a medication used to treat various conditions, including epilepsy, nerve pain, and anxiety disorders. The active ingredient, gabapentin, belongs to a class of drugs known as anticonvulsants, which work by affecting the way that nerves send messages to your brain.

What is Gabapentin Used For?

Gabapentin is primarily used to treat:

1. Epilepsy: Gabapentin is used in combination with other medications to control partial seizures and generalized seizures.
2. Postherpetic Neuralgia (PHN): Gabapentin helps to relieve nerve pain that occurs after a herpes zoster (shingles) infection.

How Does Gabapentin Work?

The exact mechanism of action of gabapentin is not fully understood, but it is believed to:

1. Bind to Voltage-Gated Calcium Channels: Gabapentin binds to specific receptors on nerve cells, which reduces the release of excitatory neurotransmitters and decreases the excitability of nerve cells.
2. Increase the Inhibitory Neurotransmitter GABA: Gabapentin may increase the production of GABA, an inhibitory neurotransmitter that helps to calm down nerve activity.
3. Reduce the Release of Pain-Related Neurotransmitters: Gabapentin may decrease the release of substances that transmit pain signals, such as substance P and calcitonin gene-related peptide.
