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 and other neuropathic pain conditions in adults.

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

Gabapentin is used to manage conditions involving neuropathic pain and seizure activity.

- Partial seizures: reduces the frequency of seizure episodes in adults. - Postherpetic neuralgia: alleviates persistent pain following shingles. - Neuropathic pain: provides analgesic relief in various peripheral neuropathies. - Restless legs syndrome: diminishes uncomfortable sensations and urges to move the legs.

Common side effects are generally mild to moderate and may resolve with continued therapy.

Common Side Effects: - Dizziness: sensation of light‑headedness or unsteadiness. - Somnolence: increased sleepiness or fatigue. - Peripheral edema: swelling of the lower extremities. - Weight gain: gradual increase in body weight.

Serious or Rare Side Effects: - Suicidal ideation: thoughts of self‑harm requiring immediate medical attention. - Severe allergic reactions: including Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Respiratory depression: marked slowing of breathing, especially when combined with other depressants. - Angioedema: rapid swelling of face, lips, tongue or throat. - Blood dyscrasias: rare cases of agranulocytosis or thrombocytopenia. - Hepatic failure: signs of liver dysfunction such as jaundice or elevated enzymes.

Before initiating therapy, consider the following safety measures.

- Renal function: adjust dose in patients with impaired renal clearance. - Pregnancy: use only if the potential benefit justifies the potential risk to the fetus. - Elderly: monitor for dizziness and falls due to increased sedation. - Concomitant CNS depressants: assess for additive sedation and respiratory effects. - Store at room temperature: keep in the original container, protect from moisture and light.

Gabapentin may interact with several drug classes; awareness helps prevent adverse outcomes.

Major Interactions (Avoid): - Antacids containing aluminum or magnesium: reduce gabapentin absorption. - Opioids: increase risk of respiratory depression and profound sedation. - CNS depressants (e.g., benzodiazepines): may cause excessive sedation.

Moderate Interactions (Monitor Closely): - Diuretics: may raise gabapentin plasma concentrations. - ACE inhibitors: monitor renal function when used together. - Alcohol: can enhance central nervous system depressive effects.
