Neurontin (Gabapentin)

Gabapentin, the active ingredient in Neurontin, is a gabapentinoid presented as an oral tablet for oral use. It is used as an adjunctive therapy for partial seizures and to relieve neuropathic pain conditions such as postherpetic neuralgia and restless legs syndrome.

GNH USA supplies Neurontin as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Neurontin (gabapentin) acts on the nervous system to manage seizure activity and neuropathic pain conditions.

- Partial seizures: reduces seizure frequency when added to existing antiepileptic therapy. - Postherpetic neuralgia: alleviates chronic pain following shingles. - Neuropathic pain: improves pain control in diabetic and other peripheral neuropathies. - Restless legs syndrome: diminishes uncomfortable sensations and urges to move the legs.

Gabapentin is generally well tolerated, but a range of adverse reactions can occur.

Common Side Effects: - Dizziness: sensation of light‑headedness or unsteadiness. - Somnolence: increased sleepiness or fatigue. - Peripheral edema: swelling of the lower limbs. - Ataxia: impaired coordination and balance. - Visual disturbances: blurred vision or double vision. - Weight gain: modest increase in body weight.

Serious or Rare Side Effects: - Suicidal ideation: thoughts of self‑harm requiring immediate evaluation. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Angioedema: rapid swelling of face, lips or throat. - Hematologic abnormalities: anemia, leukopenia or thrombocytopenia. - Respiratory depression: especially when combined with other CNS depressants. - Hepatic dysfunction: elevated liver enzymes or hepatitis.

When prescribing gabapentin, clinicians should consider patient‑specific factors and monitor for safety.

- Renal impairment: dose adjustment may be required due to reduced clearance. - Pregnancy: use only if the potential benefit justifies the potential risk to the fetus. - Elderly patients: monitor for falls and increased sedation. - Concomitant CNS depressants: risk of enhanced drowsiness and respiratory depression. - Abrupt discontinuation: taper the dose to avoid withdrawal symptoms such as anxiety or seizures. - Store at ambient temperature below 25°C: keep in the original pack, protect from moisture.

Gabapentin can interact with several drug classes, influencing efficacy or safety.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: may markedly reduce gabapentin absorption. - Opioids: combined use can increase risk of respiratory depression and profound sedation. - Alcohol: potentiates central nervous system depression.

Moderate Interactions (Monitor Closely): - Benzodiazepines and other sedatives: monitor for additive sedation. - NSAIDs: may increase risk of renal impairment, especially in patients with pre‑existing kidney disease. - ACE inhibitors or ARBs: watch for alterations in potassium balance and renal function.
