Neurontin (Gabapentin)

Gabapentin, the active ingredient in Neurontin, is an anticonvulsant presented as an oral tablet for oral use. It treats partial seizures, postherpetic neuralgia, neuropathic pain and restless legs syndrome in appropriate patients.

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

Gabapentin is used to manage neurological and pain conditions that involve abnormal neuronal excitability.

Partial seizures: reduces seizure frequency and severity. Postherpetic neuralgia: alleviates chronic pain following shingles. Neuropathic pain: relieves pain associated with diabetic neuropathy and other nerve injuries. Restless legs syndrome: decreases uncomfortable sensations and the urge to move the legs.

Gabapentin may cause a range of adverse reactions.

Common Side Effects: - Dizziness - Somnolence - Fatigue - Peripheral edema - Nausea - Weight gain

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis - Anaphylactic reactions - Suicidal thoughts or behavior - Respiratory depression, especially with concomitant CNS depressants - Angioedema - Severe hematologic abnormalities such as agranulocytosis

When prescribing gabapentin, clinicians should consider several safety measures.

Assess renal function: adjust dose in patients with renal impairment. Monitor for mood changes: watch for depression or suicidal ideation. Avoid abrupt discontinuation: taper the dose to prevent withdrawal symptoms. Use caution in elderly: increased sensitivity to central nervous system effects. Pregnancy: limited data; discuss risks and benefits with the patient. Store at room temperature: keep in the original container, protect from moisture.

Gabapentin can interact with other medicines, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: reduce gabapentin absorption. - Opioids, benzodiazepines, or other CNS depressants: increase sedation and respiratory depression. - Morphine: may enhance respiratory depression. - Alcohol: additive central nervous system depression. - HIV protease inhibitors: increase gabapentin plasma levels.

Moderate Interactions (Monitor Closely): - NSAIDs: may increase risk of renal dysfunction. - Diuretics: monitor electrolytes and renal function. - ACE inhibitors or ARBs: watch for renal impairment. - Carbamazepine: may reduce gabapentin efficacy. - SSRIs or other antidepressants: monitor for enhanced CNS effects.
