INDICATION

VIMPAT® is indicated in patients 17 years and older with partial-onset seizures as monotherapy or adjunctive therapy. VIMPAT injection for intravenous use is an alternative when oral administration is temporarily not feasible.

SELECT IMPORTANT SAFETY INFORMATION

VIMPAT is associated with important warnings and precautions including suicidal behavior and ideation, dizziness and ataxia, cardiac rhythm and conduction abnormalities, syncope, and Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), also known as multi-organ hypersensitivity.

In the monotherapy clinical trial, adverse reactions were generally similar to those observed and attributed to drug in adjunctive placebo-controlled trials, with the exception of insomnia (observed at a higher rate of ≥2%). In adjunctive placebo-controlled trials, the most common adverse reactions (≥10% and greater than placebo) were dizziness, headache, nausea, and diplopia.

VIMPAT is a Schedule V controlled substance.

(Tablets not shown at actual size.)

Recommended maintenance dose

200 mg/day to 400 mg/day (100 mg-200 mg twice-daily). Titrate based on tolerability and response.

Adverse Reactions

In the placebo-controlled clinical trials, the most frequently seen adverse reaction with VIMPAT was dizziness (31% vs 8% placebo). Other common adverse reactions occurring in ≥10 percent of VIMPAT-treated patients, and greater than placebo, were headache, nausea, and diplopia.

200 mg LOADING DOSE |

Use the VIMPAT loading dose when your patients need to get to a therapeutic dose more rapidly than standard titration allows

A single loading dose of 200 mg approximates steady-state concentrations comparable to the 100 mg twice-daily oral administration.

(Formulations not shown at actual size.)

Loading dose administration2

VIMPAT may be initiated with a single loading dose of 200 mg (oral or injection) followed approximately 12 hours later by 100 mg twice-daily (200 mg/day).

  • Based on individual response and tolerability, the dose can be increased at weekly intervals by 50 mg twice-daily (100 mg/day), as needed, up to the recommended monotherapy (300 mg/day to 400 mg/day) or adjunctive therapy (200 mg/day to 400 mg/day) maintenance dose
  • The loading dose should be administered with medical supervision considering the VIMPAT pharmacokinetics and increased incidence of CNS adverse reactions

Adverse Reactions

When administering a loading dose, the incidence of CNS adverse reactions, such as dizziness, somnolence, and paresthesia may be higher with 15-minute administration than over a 30- to 60-minute period.

INTRAVENOUS DOSING |

Special considerations when using injection


(Formulation not shown at actual size.)

VIMPAT injection for intravenous use—indicated as short-term replacement when oral administration is not feasible2

  • Intravenous injection can be administered in the same dosing regimens as oral dosing, including the loading dose. The dose may be infused over a period of 15 to 60 minutes
  • Infusion over 30 to 60 minutes is preferable, and should be used when 15-minute administration is not required
  • Closely monitor patients with known cardiac conduction problems, on concomitant medications that prolong PR interval, or with severe cardiac disease, as intravenous infusion of VIMPAT may cause bradycardia or AV blocks in these patients
  • Cmax reached by end of infusion time
  • Oral to intravenous (IV): the initial total daily IV dosage regimen of VIMPAT should be equivalent to the total daily dosage regimen of oral VIMPAT
  • Adverse reactions with IV administration generally appeared similar to those observed with the oral formulation, although IV administration was associated with local adverse events, such as injection site pain or discomfort (2.5%), irritation (1%), and erythema (0.5%)

Intravenous injection solution preparation

  • VIMPAT injection can be administered intravenously without further dilution or may be mixed with diluents listed below. The diluted solution should not be stored for more than 4 hours at room temperature
  • Diluents: Sodium Chloride Injection 0.9% (w/v), Dextrose Injection 5% (w/v), Lactated Ringer’s Injection
  • Product with particulate matter or discoloration should not be used
  • Any unused portion of VIMPAT injection should be discarded

ORAL SOLUTION DOSING |

Special considerations when using oral solution

VIMPAT® (lacosamide) CV Oral Administration Chart

VIMPAT oral solution—a dosing option for patients who cannot swallow tablets2

  • Does not need to be refrigerated or shaken prior to administration
  • For accurate dosing, healthcare providers should offer a calibrated measuring device to patients prescribed VIMPAT oral solution
  • Any unused oral solution should be discarded after 7 weeks of first opening the bottle
  • IV to oral: begin oral administration at the equivalent daily dosage and frequency of the IV administration
  • VIMPAT oral solution contains aspartame, a source of phenylalanine. A 200 mg dose of VIMPAT oral solution (equivalent to 20 mL) contains 0.32 mg of phenylalanine
  • Multiple bottle sizes (465 mL and 200 mL) provide convenient options for the pharmacy

SELECT DOSING IN SPECIAL POPULATIONS2 |

  • Dosage adjustments are recommended for patients with mild or moderate hepatic impairment or severe renal impairment. Use in patients with severe hepatic impairment is not recommended. Dose titration should be performed with caution in all patients with renal and/or hepatic impairment
VIMPAT® (lacosamide) CV Select Dosing in Special Populations
  • Following a 4-hour hemodialysis treatment, AUC of VIMPAT is reduced by approximately 50%, and dosage supplementation of up to 50% following hemodialysis should be considered

Important Safety Information

Warnings and Precautions

Suicidal Behavior and Ideation

Antiepileptic drugs (AEDs), including VIMPAT, increase the risk of suicidal behavior and ideation. Monitor patients taking VIMPAT for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Advise patients and caregivers to be alert for these behavioral changes and to immediately report them to the healthcare provider.

Dizziness and Ataxia

VIMPAT may cause dizziness and ataxia. The onset of dizziness and ataxia was most commonly observed during titration. Advise patients not to drive, operate complex machinery, or engage in other hazardous activities until they are familiar with the effects of VIMPAT on their ability to perform such activities.

Cardiac Rhythm and Conduction Abnormalities

PR interval prolongation

Dose-dependent prolongations in PR interval with VIMPAT have been observed in clinical studies in patients and in healthy volunteers. Second-degree and complete AV block have been reported in patients in pain studies and in patients with seizures. When VIMPAT is given with other drugs that prolong the PR interval, further PR prolongation is possible.

Use VIMPAT with caution in patients with known cardiac conduction problems (e.g., marked first-degree AV block, second-degree or higher AV block and sick sinus syndrome without pacemaker), sodium channelopathies (e.g., Brugada Syndrome), or with severe cardiac disease such as myocardial ischemia or heart failure, or structural heart disease. Also, use VIMPAT with caution in patients on concomitant medications that prolong PR interval (e.g., beta-blockers and calcium channel blockers) because of a risk of AV block or bradycardia. In such patients, obtaining an ECG before beginning VIMPAT, and after VIMPAT is titrated to steady-state, is recommended. In addition, closely monitor these patients if they are administered VIMPAT through the intravenous route.

Atrial fibrillation and Atrial flutter

VIMPAT administration may predispose to atrial arrhythmias (atrial fibrillation or flutter), especially in patients with diabetic neuropathy and/or cardiovascular disease.

Syncope

VIMPAT may cause syncope.

Withdrawal of Antiepileptic Drugs

Gradually withdraw VIMPAT (over a minimum of 1 week) to minimize the potential of increased seizure frequency.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)

Also known as multi-organ hypersensitivity, has been reported with antiepileptic drugs. Some of these events have been fatal or life-threatening. If signs or symptoms are present, immediately evaluate the patient. Discontinue VIMPAT if an alternative etiology for the signs and symptoms cannot be established.

Phenylketonurics

VIMPAT oral solution contains aspartame, a source of phenylalanine. A 200 mg dose of VIMPAT oral solution (equivalent to 20 mL) contains 0.32 mg of phenylalanine.

Adverse Reactions

Adjunctive therapy

In the placebo-controlled clinical trials, the most frequently seen adverse reaction with VIMPAT was dizziness (31% vs 8% placebo). Other common adverse reactions occurring in ≥10 percent of VIMPAT-treated patients, and greater than placebo, were headache, nausea, and diplopia.

Monotherapy

In the clinical trial, adverse reactions were generally similar to those observed and attributed to drug in adjunctive placebo-controlled trials, with the exception of insomnia (occurred at a higher rate of ≥2%).

Injection

In adjunctive therapy clinical trials, adverse reactions with intravenous administration generally were similar to those that occurred with the oral formulation, although intravenous administration was associated with local adverse reactions such as injection site pain or discomfort (2.5%), irritation (1%), and erythema (0.5%). When administering a loading dose, the incidence of CNS adverse reactions, such as dizziness, somnolence, and paresthesia may be higher with 15-minute administration than over a 30- to 60-minute period.

Dosing Considerations

The loading dose should be administered with medical supervision considering the VIMPAT pharmacokinetics and increased incidence of CNS adverse reactions. Dosage adjustments are recommended for patients with mild or moderate hepatic impairment or severe renal impairment. Use in patients with severe hepatic impairment is not recommended. Perform dose titration with caution in all patients with renal and/or hepatic impairment.
