Lacomax Oral Solution 50 mg/5 ml contains Lacosamide, an antiepileptic medication indicated for the management of partial-onset seizures in adults and pediatric patients aged 4 years and older. It is used either as monotherapy or as adjunctive therapy in patients who require additional seizure control. Lacosamide helps to stabilize hyperexcitable neuronal membranes and inhibit repetitive neuronal firing, reducing the frequency and severity of seizures. Its oral solution formulation allows accurate dosing for pediatric patients and individuals who have difficulty swallowing tablets.

Therapeutic Class

Antiepileptic Drug (AED)

Indications

Lacomax Oral Solution is indicated for:

• Partial-onset seizures in adults and children aged 4 years and above

• Adjunctive therapy in patients whose seizures are not adequately controlled with other antiepileptic medications

• Suitable for patients who require flexible dosing, especially children and elderly patients

By targeting sodium channels in the brain, Lacosamide reduces abnormal electrical activity, helping to control seizure events and improve patient quality of life.

Pharmacology

Lacosamide selectively enhances slow inactivation of voltage-gated sodium channels, stabilizing hyperexcitable neuronal membranes without affecting normal neuronal activity. Unlike some other sodium channel blockers, Lacosamide does not alter fast inactivation or normal neuronal conduction, which minimizes effects on normal brain function.

• Absorption: Rapid and nearly complete oral absorption

• Metabolism: Partially metabolized in the liver via CYP2C19 and non-CYP pathways

• Excretion: Primarily excreted in urine, mostly as unchanged drug

• Half-life: Approximately 13 hours, allowing for twice-daily dosing in most patients

Lacosamide demonstrates linear pharmacokinetics, with minimal drug-drug interactions compared to other antiepileptic drugs.

Dosage and Administration

Adults:

• Initial dose: 50 mg twice daily

• Titration: Increase by 50 mg twice daily at one-week intervals as tolerated

• Maintenance dose: 100–200 mg twice daily (maximum 400 mg/day)

Pediatric Patients (4–16 years):

• Initial dose: 1 mg/kg twice daily

• Titration: Increase weekly by 1 mg/kg twice daily

• Maintenance dose: 3–6 mg/kg twice daily (maximum 200 mg/day)

Administration Instructions:

• The oral solution can be taken with or without food

• Use the provided measuring device to ensure accurate dosing

• Do not mix with other liquids unless recommended by a healthcare provider

Contraindications

• Hypersensitivity to Lacosamide or any component of the formulation

• Patients with known PR interval prolongation or severe cardiac conduction disorders without close monitoring

Side Effects

Common side effects include:

• Dizziness, headache, and nausea

• Fatigue and somnolence

• Diplopia (double vision) or blurred vision

• Rarely, cardiac conduction abnormalities such as PR interval prolongation

Most adverse effects are mild to moderate and often resolve with continued treatment.

Precautions and Warnings

• Use caution in patients with heart disease, especially those with conduction abnormalities

• May cause dizziness or ataxia; avoid driving or operating machinery until response is known

• Gradual titration is recommended to minimize adverse effects

• Monitor renal and hepatic function in patients with impairment

Drug Interactions

• Lacosamide has a low potential for interactions but may interact with other antiepileptics or drugs affecting cardiac conduction

• Concomitant use with digoxin or calcium channel blockers requires monitoring

Pregnancy and Lactation

• Pregnancy: Use only if clearly needed; limited data suggest low teratogenic risk

• Breastfeeding: Lacosamide is excreted in breast milk; caution is advised

Storage Conditions

• Store in a cool, dry place below 30°C, protected from light and moisture

• Keep out of reach of children

• Use the reconstituted solution within the period recommended on the label

Mode of Action

Lacosamide acts by enhancing slow inactivation of voltage-gated sodium channels, stabilizing hyperexcitable neurons and preventing repetitive firing. This targeted mechanism reduces abnormal neuronal excitability while preserving normal neuronal signaling, effectively controlling partial-onset seizures.
