Neurontin (Gabapentin)

Gabapentin binds to the α2δ auxiliary subunit of voltage‑gated calcium channels in the central nervous system. This binding limits calcium entry into nerve terminals, which in turn reduces the release of excitatory neurotransmitters such as glutamate and substance P, dampening abnormal neuronal firing that underlies seizures and neuropathic pain.

The prescribed dose of gabapentin is individualized by the treating clinician based on the specific indication, patient age, renal function, and response to therapy. Dosage titration is typically started low and increased gradually to achieve therapeutic effect while minimizing side effects.

The safety of gabapentin in pregnancy and lactation has not been definitively established. It is classified as pregnancy category unknown, and clinicians weigh potential benefits against possible risks before prescribing to pregnant or nursing women.

GNH India works with hospitals, pharmacies and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details and any necessary import documentation.

Gabapentin and pregabalin are both gabapentinoids that share a similar mechanism of binding to the α2δ calcium‑channel subunit. Pregabalin generally has higher potency and more predictable pharmacokinetics, which may allow lower dosing, while gabapentin is often chosen for its longer clinical experience and lower cost in many markets.

Neurontin tablets should be stored at ambient temperature, below 25 °C, in the original packaging to protect them from moisture and excessive heat. Keep the container tightly closed and out of direct sunlight to maintain product stability.

Neurontin is supplied as oral tablets that are swallowed whole with a glass of water. It is taken by mouth, usually with or without food, as directed by the prescribing healthcare professional. Doses are spaced according to the regimen set by the prescriber.

Serious adverse reactions to gabapentin, though rare, include severe allergic responses such as Stevens‑Johnson syndrome, respiratory depression especially when combined with other CNS depressants, and emergence or worsening of suicidal thoughts or behaviors. Prompt medical attention is required if any of these occur.

Gabapentin is contraindicated in patients with known hypersensitivity to gabapentin or any component of the formulation. Caution is advised for individuals with severe renal impairment, uncontrolled psychiatric conditions, or those taking multiple CNS depressants, as they may be at higher risk for adverse effects.
