Manufacturer: HAB Pharmaceuticals & Research Ltd.
Dosage Form: Oral Capsule
Strength: 300 mg
Drug Class: Anticonvulsant / Neuropathic Pain Agent

Therapeutic Uses
Gabasign 300 mg is commonly prescribed for the following conditions:
- Neuropathic Pain: Effective in treating nerve pain due to diabetes, shingles (postherpetic neuralgia), or spinal cord injury.

Gabapentin works by binding to the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system. This modulates the release of excitatory neurotransmitters such as glutamate and substance P, reducing nerve excitability and alleviating pain, seizures, and anxiety.
