Indications & Clinical Uses

Lacosamide is an anticonvulsant that acts on neuronal sodium channels to control seizure activity.

  • Partial‑onset seizures: reduces the frequency and severity of focal seizures.
  • Epilepsy (adjunct therapy): helps achieve better overall seizure control when added to existing regimens.
  • Refractory focal epilepsy: provides an additional option for patients whose seizures are not controlled by first‑line agents.

How It Works

  • Lacosamide enhances the slow inactivation of voltage‑gated sodium channels, stabilizing hyperexcitable neuronal membranes and decreasing repetitive neuronal firing. This modulation reduces neuronal excitability without affecting the fast inactivation phase, contributing to its antiepileptic effect.

Side Effects

Lacosamide may cause a range of adverse reactions, which vary in frequency and severity.

Common Side Effects

  • Dizziness: sensation of light‑headedness or unsteadiness.
  • Fatigue: feeling unusually tired or weak.
  • Nausea: upset stomach or urge to vomit.
  • Headache: mild to moderate pain in the head.
  • Blurred vision: temporary visual disturbances.
  • Diplopia: double vision.

Serious or Rare Side Effects

  • Stevens‑Johnson syndrome: severe skin reaction requiring immediate medical attention.
  • Cardiac arrhythmia: irregular heart rhythm, especially in patients with pre‑existing conditions.
  • Suicidal thoughts: emergence of depressive symptoms or suicidal ideation.
  • Severe hypersensitivity: anaphylaxis or angioedema.
  • Rhabdomyolysis: muscle breakdown leading to kidney injury.
  • Life‑threatening skin reactions: toxic epidermal necrolysis.

Precautions & Warnings

Before prescribing Lacosamide, clinicians should consider several safety measures.

  • Cardiac monitoring: assess ECG for PR‑interval prolongation in patients with cardiac disease.
  • Renal function: adjust use in patients with impaired renal clearance.
  • Hepatic impairment: evaluate liver function and consider dose adjustment.
  • Concomitant CNS depressants: monitor for enhanced sedation or respiratory depression.
  • Abrupt discontinuation: taper gradually to avoid seizure exacerbation.
  • Store at below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Avoid Interactions

Lacosamide can interact with other medicines, influencing its efficacy or safety.

Major Interactions (Avoid)

  • Strong CYP3A4 inhibitors (e.g., ketoconazole): may increase lacosamide plasma levels.
  • Other sodium‑channel blockers (e.g., carbamazepine, phenytoin): additive risk of cardiac conduction effects.
  • QT‑prolonging agents (e.g., amiodarone): heightened risk of arrhythmias.

Moderate Interactions (Monitor Closely)

  • Alcohol and CNS depressants: may enhance sedation and dizziness.
  • Antacids: can modestly affect absorption; monitor therapeutic response.

Frequently Asked Questions

Lacosamide Viatris is used as an adjunctive therapy for the treatment of partial‑onset (focal) seizures in patients with epilepsy. It helps reduce seizure frequency when added to other antiepileptic medications.

Lacosamide enhances the slow inactivation of voltage‑gated sodium channels in neuronal membranes. This stabilizes hyper‑excitable neurons, limiting repetitive firing and thereby decreasing seizure activity.

The dosage of Lacosamide Viatris is individualized by the prescribing clinician based on the patient’s clinical condition, response, and tolerability. Only a qualified healthcare professional should determine the appropriate regimen.

Safety data for lacosamide in pregnancy and lactation are limited. Prescribers should weigh potential benefits against risks and consider alternative therapies when possible. Breastfeeding decisions should be made in consultation with a healthcare provider.

To place an order, submit an enquiry on the product page at gnhindia.com, specifying the required quantity. 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.

Lacosamide’s unique mechanism—enhancing slow sodium‑channel inactivation—differs from many traditional agents that target fast inactivation. This can provide additional seizure control for patients who are not fully responsive to other antiepileptics, often with a distinct side‑effect profile.

Store the product at temperatures below 25 °C in its original packaging. Protect it from moisture, direct sunlight, and extreme heat to maintain potency and stability.

Lacosamide Viatris is administered orally, typically as a tablet or oral solution, and should be taken with or without food as directed by the prescriber. Consistent dosing times help maintain stable blood levels.

Serious risks include cardiac conduction abnormalities such as PR‑interval prolongation, severe skin reactions like Stevens‑Johnson syndrome, and rare cases of suicidal ideation. Patients should be monitored for these events, especially during treatment initiation or dose changes.

Lacosamide is contraindicated in patients with known hypersensitivity to the drug or any of its components. Caution is also advised for individuals with significant cardiac conduction disorders, severe hepatic impairment, or those taking interacting medications that could raise plasma levels.
