Lacomax 50 mg is an oral and injectable medication used for the management of partial-onset seizures in adults and pediatric patients 4 years and older. It acts on neuronal sodium channels and neural signaling pathways to reduce seizure frequency and severity. Lacomax is designed for both monotherapy and adjunctive therapy and offers flexible dosing based on age, body weight, and clinical response.

Therapeutic Class

Atypical Anticonvulsant / Anti-Seizure Drug

Indications

Lacomax 50 mg is indicated for:

• Partial-onset seizures in patients aged 4 years and older (oral use)

• Partial-onset seizures in adults (17 years and older) when oral administration is temporarily not feasible (intravenous use)

Pharmacology

Lacomax 50 mg is believed to exert its effects primarily by:

• Inhibition of voltage-gated sodium channels, preferentially in depolarized neurons

• Binding to collapsin response mediator protein-2 (CRMP-2), which is involved in neuronal differentiation and axonal growth

These mechanisms reduce hyperexcitability in neurons, decreasing the occurrence and severity of seizures.

Dosage and Administration

Oral Administration – Adults (≥17 years)

• Monotherapy: Initial 100 mg twice daily; titrate up to maximum 200 mg twice daily

• Adjunctive therapy: Initial 50 mg twice daily; titrate up to maximum 200 mg twice daily

Oral Administration – Pediatric (4 to <17 years)

• Dosage based on body weight, given twice daily

• Increase dosage based on clinical response and tolerability, no more frequently than once per week

Intravenous Administration – Adults (≥17 years)

• Used only when oral administration is temporarily not feasible

• Same dosing regimen as oral

• Infuse over 15–60 minutes

• ECG recommended before initiation in certain patients

Drug Interactions

• CYP3A4 or CYP2C9 inhibitors: May increase Lacomax exposure; dose adjustment may be needed

• Medications prolonging PR interval (e.g., beta-blockers, calcium channel blockers): Use with caution; ECG monitoring recommended

• IV route: Patients on drugs affecting PR interval should be closely monitored

Contraindications

• None reported

Side Effects

Common adverse effects include:

• Adults (≥10%): Diplopia, headache, dizziness, nausea

• Pediatric patients: Similar to adults

• Additional effects: Ataxia, syncope, and other mild CNS symptoms

Precautions & Warnings

• Monitor for suicidal ideation or behavior

• Gradual withdrawal recommended to prevent increased seizure frequency

• ECG monitoring in patients with cardiac conduction abnormalities or concomitant medications that prolong PR interval

• Discontinue immediately in case of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) or multi-organ hypersensitivity

Pregnancy & Lactation

• Pregnancy: Based on animal studies, may cause fetal harm

• Lactation: Use caution; dose adjustments may be necessary

Storage Conditions

• Store at 20°C to 25°C

• Protect from moisture and light

• Keep out of reach of children

Mode of Action

• Inhibits hyperactive sodium channels in depolarized neurons

• Modulates neuronal signaling via CRMP-2 binding, contributing to seizure control

Special Populations

• Renal impairment: Dose adjustment recommended

• Hepatic impairment: Dose adjustment for mild/moderate cases; avoid in severe impairment
