Neurontin (Gabapentin)

Gabapentin binds to the α2‑δ subunit of voltage‑gated calcium channels in the central nervous system. This binding limits calcium entry into nerve cells, which in turn reduces the release of excitatory neurotransmitters such as glutamate and substance P. The result is decreased neuronal hyperexcitability, which underlies its anticonvulsant and analgesic effects.

The appropriate dose of Neurontin is individualized by the prescribing clinician based on the specific indication, patient age, renal function, and response to therapy. Dosage adjustments may be required for patients with impaired kidney function or when the drug is used in combination with other central nervous system depressants.

Safety data for gabapentin in pregnancy and lactation are limited. It should only be used when the potential benefit to the mother outweighs any possible risk to the fetus. Women who are breastfeeding should discuss potential exposure with their healthcare provider, as gabapentin can be excreted in breast milk.

To place an order, submit an enquiry on the Neurontin product page at gnhindia.com, specifying the required quantity. GNH India supplies hospitals, pharmacies and procurement teams across international markets. After submission, the sales team will verify trade or institutional credentials and respond with pricing, availability, shipping details and any necessary import documentation.

Both gabapentin (Neurontin) and pregabalin belong to the gabapentinoid class and share a similar mechanism of binding to the α2‑δ calcium‑channel subunit. Pregabalin generally has higher bioavailability and may achieve therapeutic levels at lower doses, while gabapentin often requires titration over several weeks. Choice between them depends on clinical response, tolerability, and prescribing preferences.

Store Neurontin at ambient temperature, below 25 °C. Keep the product in its original packaging, protect it from moisture and direct heat, and ensure the container is tightly closed to maintain stability throughout its shelf life.

Neurontin is taken orally, usually with or without food, as directed by the prescriber. The tablets (or capsules) should be swallowed whole with a glass of water. If dose splitting is required, only tablets designed for that purpose should be divided, following the clinician’s instructions.

Serious risks include severe allergic reactions such as Stevens‑Johnson syndrome, respiratory depression especially when combined with opioids or other depressants, and emergence of suicidal thoughts or behaviors. Patients should be monitored closely for signs of hypersensitivity, breathing difficulties, or marked mood changes, and seek immediate medical attention if these occur.

Neurontin should be avoided in individuals with known hypersensitivity to gabapentin or any of its excipients. Caution is also advised for patients with severe renal impairment who cannot be dose‑adjusted, and for those taking medications that may cause dangerous additive CNS depression. Pregnant or breastfeeding women should only use it when clearly indicated by a healthcare professional.
