What is Gabapentin?

Gabapentin belongs to a class of medications known as anticonvulsants or antiepileptic drugs. Its primary mechanism of action involves modulating the activity of certain neurotransmitters in the brain, particularly gamma-aminobutyric acid (GABA). By influencing these neurotransmitters, gabapentin helps to calm overactive nerve signals, which can reduce seizures, alleviate nerve pain, and potentially impact mood regulation.

Gabapentin is available in several forms and strengths to accommodate various treatment needs:

1. Tablets: 100mg, 300mg, 400mg, 600mg, 800mg
2. Capsules: 100mg, 300mg, 400mg
3. Oral solution: 250mg/5mL
4. Extended-release tablets: 300mg, 600mg
5. Injections: Available for hospital use

The variety of forms and strengths allows healthcare providers to tailor treatment plans to individual patient needs and conditions.
