Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

1 INDICATIONS AND USAGE Eslicarbazepine acetate tablets are indicated for the treatment of partial-onset seizures in patients 4 years of age and older. Eslicarbazepine acetate tablets are indicated for the treatment of partial-onset seizures in patients 4 years of age and older. ( 1 )

⏱️ Dosage and Administration ~3 min read ▾

2 DOSAGE AND ADMINISTRATION Adult Patients: The recommended initial dosage of eslicarbazepine acetate tablets is 400 mg once daily. For some patients, treatment may be initiated at 800 mg once daily if the need for seizure reduction outweighs an increased risk of adverse reactions. Increase the dose in weekly increments of 400 mg to 600 mg once daily, based on clinical response and tolerability, to a recommended maintenance dosage of 800 mg to 1,600 mg once daily.

( 2.2 ) Pediatric Patients: The recommended dosage of eslicarbazepine acetate tablets is based on body weight and is administered orally once daily. Increase the dose in weekly intervals based on clinical response and tolerability, to the recommended maintenance dosage. ( 2.2 ) Patients with Moderate or Severe Renal Impairment: Reduce dosage by 50%.

( 2.4 )

2.1Important Administration Instructions Instruct patients to administer eslicarbazepine acetate tablets either as whole or as crushed tablets. Instruct patients to take eslicarbazepine acetate tablets either with or without food. The eslicarbazepine acetate tablets dosing regimen depends on age, weight, and renal function.

2.2General Dosing Recommendations Monotherapy and Adjunctive Therapy Adult Patients The recommended initial dosage of eslicarbazepine acetate tablets is 400 mg administered orally once daily. For some patients, treatment may be initiated at 800 mg once daily if the need for seizure reduction outweighs an increased risk of adverse reactions during initiation [see Adverse Reactions (6.1) ] . Dosage should be increased in weekly increments of 400 mg to 600 mg, based on clinical response and tolerability, to a recommended maintenance dosage of 800 mg to 1,600 mg once daily.

For patients on eslicarbazepine acetate tablets monotherapy, the 800 mg once daily maintenance dose should generally be considered in patients who are unable to tolerate a 1,200 mg daily dose. For patients on eslicarbazepine acetate tablets adjunctive therapy, the 1,600 mg daily dose should generally be considered in patients who did not achieve a satisfactory response with a 1,200 mg daily dose. Pediatric Patients (4 to 17 Years of Age) In pediatric patients 4 to 17 years of age, the recommended dosing regimen is dependent upon body weight and is administered orally once daily.

The recommended initial dosage of eslicarbazepine acetate tablets is shown in Table 1. Dosage should be increased based on clinical response and tolerability, no more frequently than once per week. Titration increments should not exceed those shown in Table 1.

The daily maintenance dosage should not exceed the maintenance dosage for each body weight range shown in Table 1. Table 1: Eslicarbazepine Acetate Tablets Once Daily Dosage Schedule for Pediatric Patients 4 to 17 Years of Age Body Weight Range Initial and Maximum Titration Increment Dosage (mg/day) Maintenance Dosage (mg/day) 11 to 21 kg 200 400 to 600 22 to 31 kg 300 500 to 800 32 to 38 kg 300 600 to 900 more than 38 kg 400 800 to 1,200

2.3Dosage Modifications with Other Antiepileptic Drugs Some adverse reactions occur more frequently when patients take eslicarbazepine acetate tablets adjunctively with carbamazepine [see Warnings and Precautions (5.6) ] . However, carbamazepine reduces the plasma concentration of eslicarbazepine [see Drug Interactions (7.1) ] . When eslicarbazepine acetate tablets and carbamazepine are taken concomitantly, the dose of eslicarbazepine acetate tablets or carbamazepine may need to be adjusted based on efficacy and tolerability.

For patients taking other enzyme-inducing AEDs (i.e., phenobarbital, phenytoin, and primidone), higher doses of eslicarbazepine acetate tablets may be needed [see Drug Interactions (7.1) ]. Eslicarbazepine acetate tablets should not be taken as an adjunctive therapy with oxcarbazepine.

4 CONTRAINDICATIONS Eslicarbazepine acetate tablets are contraindicated in patients with a hypersensitivity to eslicarbazepine acetate or oxcarbazepine [see Warnings and Precautions ( 5.2 , 5.3 , and 5.4 )]. Hypersensitivity to eslicarbazepine acetate or oxcarbazepine. ( 4 )

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Suicidal Behavior and Ideation: Monitor for suicidal thoughts or behavior. ( 5.1 ) Serious Dermatologic Reactions, Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), Anaphylactic Reactions and Angioedema: Monitor and discontinue if another cause cannot be established. ( 5.2 , 5.3 , 5.4 ) Hyponatremia: Monitor sodium levels in patients at risk or patients experiencing hyponatremia symptoms.

( 5.5 ) Neurological Adverse Reactions: Monitor for dizziness, disturbance in gait and coordination, somnolence, fatigue, cognitive dysfunction, and visual changes. Use caution when driving or operating machinery. ( 5.6 ) Withdrawal of Eslicarbazepine Acetate Tablets: Withdraw eslicarbazepine acetate tablets gradually to minimize the risk of increased seizure frequency and status epilepticus.

( 2.6 , 5.7 , 8.1 ) Drug Induced Liver Injury: Discontinue eslicarbazepine acetate tablets in patients with jaundice or evidence of significant liver injury. ( 5.8 ) Hematologic Adverse Reactions: Consider discontinuing. ( 5.10 )

5.1Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including eslicarbazepine acetate tablets, increase the risk of suicidal thoughts or behavior in patients taking these drugs for any indication. Patients treated with any AED for any indication should be monitored for the emergence or worsening of depression, suicidal thoughts or behavior, and/or any unusual changes in mood or behavior. Pooled analyses of 199 placebo-controlled clinical trials (mono- and adjunctive therapy) of 11 different AEDs showed that patients randomized to one of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% confidence interval [CI]: 1.2, 2.7) of suicidal thinking or behavior compared to patients randomized to placebo.

In these trials, which had a median treatment duration of 12 weeks, the estimated incidence of suicidal behavior or ideation among 27,863 AED-treated patients was 0.43%, compared to 0.24% among 16,029 placebo-treated patients, representing an increase of approximately one case of suicidal thinking or behavior for every 530 patients treated. There were four suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number of events is too small to allow any conclusion about drug effect on suicide.

The increased risk of suicidal thoughts or behavior with AEDs was observed as early as one week after starting treatment with AEDs and persisted for the duration of treatment assessed. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed. The risk of suicidal thoughts or behavior was generally consistent among drugs in the data analyzed.

The finding of increased risk with AEDs of varying mechanisms of action and across a range of indications suggests that the risk applies to all AEDs used for any indication. The risk did not vary substantially by age (5-100 years) in the clinical trials analyzed. Table 3 shows absolute and relative risk by indication for all evaluated AEDs.

🤒 Adverse Reactions ~3 min read ▾

6 ADVERSE REACTIONS The following adverse reactions are described in more detail in the Warnings and Precautions section of the label: Suicidal Behavior and Ideation [see Warnings and Precautions (5.1) ] Serious Dermatologic Reactions [see Warnings and Precautions (5.2) ] Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS)/Multiorgan Hypersensitivity [see Warnings and Precautions (5.3) ] Anaphylactic Reactions and Angioedema [see Warnings and Precautions (5.4) ] Hyponatremia [see Warnings and Precautions (5.5) ] Neurological Adverse Reactions [see Warnings and Precautions (5.6) ] Drug Induced Liver Injury [see Warnings and Precautions (5.8) ] Abnormal Thyroid Function Tests [see Warnings and Precautions (5.9) ] Pancytopenia, Agranulocytosis, and Leukopenia [see Warnings and Precautions (5.10) ] Most common adverse reactions in adult patients receiving eslicarbazepine acetate tablets (≥4% and ≥2% greater than placebo): dizziness, somnolence, nausea, headache, diplopia, vomiting, fatigue, vertigo, ataxia, blurred vision, and tremor.

( 6.1 ) Adverse reactions in pediatric patients are similar to those seen in adult patients. To report SUSPECTED ADVERSE REACTIONS, contact Jubilant Cadista Pharmaceuticals Inc. at 1-800-313-4623 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adult Patients In monotherapy trials in patients with partial-onset seizures [Study 1 and Study 2, see Clinical Studies (14.1) ] , 365 patients received eslicarbazepine acetate tablets, of whom 225 were treated for longer than 12 months and 134 for longer than 24 months.

Of the patients in those trials, 95% were between 18 and 65 years old; 48% were male, and 84% were Caucasian. Across controlled and uncontrolled trials in patients receiving adjunctive therapy for partial-onset seizures, 1,195 patients received eslicarbazepine acetate tablets, of whom 586 were treated for longer than 6 months and 462 for longer than 12 months. In the placebo controlled adjunctive therapy trials in patients with partial-onset seizures (Study 3, Study 4 and Study 5), 1,021 patients received eslicarbazepine acetate tablets.

Of the patients in those trials, approximately 95% were between 18 and 60 years old, approximately 50% were male, and approximately 80% were Caucasian. Monotherapy Historical Control Trials In the monotherapy epilepsy trials (Study 1 and Study 2), 13% of patients randomized to receive eslicarbazepine acetate tablets at the recommended doses of 1,200 mg and 1,600 mg once daily discontinued from the trials as a result of an adverse event. The adverse reaction most commonly (≥1% on eslicarbazepine acetate tablets) leading to discontinuation was hyponatremia.

Adverse reactions observed in these studies were generally similar to those observed and attributed to drug in adjunctive placebo-controlled studies. Because these studies did not include a placebo control group, causality could not be established. Dizziness, nausea, somnolence, and fatigue were all reported at lower incidences during the AED Withdrawal Phase and Monotherapy Phase compared with the Titration Phase.

Adjunctive Therapy Controlled Trials In the controlled adjunctive therapy epilepsy trials (Study 3, Study 4, and Study 5) , the rate of discontinuation as a result of any adverse reaction was 14% for the 800 mg dose, 25% for the 1,200 mg dose, and 7% in subjects randomized to placebo. The adverse reactions most commonly (≥1% in any eslicarbazepine acetate tablets treatment group, and greater than placebo) leading to discontinuation, in descending order of frequency, were dizziness, nausea, vomiting, ataxia, diplopia, somnolence, headache, blurred vision, vertigo, asthenia, fatigue, rash, dysarthria… [Excerpted — this section continues on DailyMed.]

🔄 Drug Interactions ~1 min read ▾

7 DRUG INTERACTIONS Carbamazepine: May need dose adjustment for eslicarbazepine acetate tablets or carbamazepine. ( 2.3 , 5.6 , 7.1 ) Phenytoin: Higher dosage of eslicarbazepine acetate tablets may be necessary and dose adjustment may be needed for phenytoin. ( 2.3 , 7.1 , 7.2 ) Phenobarbital or Primidone: Higher dosage of eslicarbazepine acetate tablets may be necessary.

( 2.3 , 7.1 ) Hormonal Contraceptives: Eslicarbazepine acetate tablets may decrease the effectiveness of hormonal contraceptives. ( 7.4 , 8.3 )

7.1Other Antiepileptic Drugs Several AEDs (e.g., carbamazepine, phenobarbital, phenytoin, and primidone) can induce enzymes that metabolize eslicarbazepine acetate tablets and can cause decreased plasma concentrations of eslicarbazepine [see Clinical Pharmacology (12.3) ]. Higher doses of eslicarbazepine acetate tablets may be needed [see Dosage and Administration (2.4) ].

7.2CYP2C19 Substrates Eslicarbazepine acetate tablets can inhibit CYP2C19, which can cause increased plasma concentrations of drugs that are metabolized by this isoenzyme (e.g., phenytoin, clobazam, and omeprazole) [see Clinical Pharmacology (12.3) ]. Dose adjustment may be needed.

7.3CYP3A4 Substrates In vivo studies suggest that eslicarbazepine acetate tablets can induce CYP3A4, decreasing plasma concentrations of drugs that are metabolized by this isoenzyme (e.g., simvastatin, lovastatin) [see Clinical Pharmacology (12.3) ]. Dose adjustment of simvastatin and lovastatin may be needed if a clinically significant change in lipids is noted.

7.4Oral Contraceptives Because concomitant use of eslicarbazepine acetate tablets and ethinylestradiol and levonorgestrel is associated with lower plasma levels of these hormones, females of reproductive potential should use additional or alternative non-hormonal birth control.

👥 Use in Specific Populations ~3 min read ▾

8 USE IN SPECIFIC POPULATIONS Pregnancy: Based on animal data, may cause fetal harm. ( 8.1 )

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to AEDs, such as eslicarbazepine acetate tablets, during pregnancy. Encourage women who are taking eslicarbazepine acetate tablets during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org. Risk Summary Limited available data with eslicarbazepine acetate tablets use in pregnant women are insufficient to inform a drug-associated risk of adverse developmental outcomes.

In oral studies conducted in pregnant mice, rats, and rabbits, eslicarbazepine acetate demonstrated developmental toxicity, including increased incidence of malformations (mice), embryolethality (rats), and fetal growth retardation (all species), at clinically relevant doses (see Data). Advise a pregnant woman of the potential risk to a fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

The background risk of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data When eslicarbazepine acetate was orally administered (150, 350, 650 mg/kg/day) to pregnant mice throughout organogenesis, increased incidences of fetal malformations was observed at all doses and fetal growth retardation was observed at the mid and high doses. A no-effect dose for adverse developmental effects was not identified.

At the lowest dose tested, plasma eslicarbazepine exposure (C max , AUC) is less than that in humans at the maximum recommended human dose (MRHD, 1,600 mg/day). Oral administration of eslicarbazepine acetate (40, 160, 320 mg/kg/day) to pregnant rabbits throughout organogenesis resulted in fetal growth retardation and increased incidences of skeletal variations at the mid and high doses. The no-effect dose (40 mg/kg/day) is less than the MRHD on a mg/m 2 basis.

Oral administration to pregnant rats (65, 125, 250 mg/kg/day) throughout organogenesis resulted in embryolethality at all doses, increased incidences of skeletal variations at the mid and high doses, and fetal growth retardation at the high dose. The lowest dose tested (65 mg/kg/day) is less than the MRHD on a mg/m 2 basis. When eslicarbazepine acetate was orally administered to female mice during pregnancy and lactation (150, 350, 650 mg/kg/day), the gestation period was prolonged at the highest dose tested.

In offspring, a persistent reduction in offspring body weight and delayed physical development and sexual maturation were observed at the mid and high doses. The lowest dose tested (150 mg/kg/day) is less than the MRHD on a mg/m 2 basis. When eslicarbazepine acetate was orally administered (65, 125, 250 mg/kg/day) to rats during pregnancy and lactation, reduced offspring body weight was seen at the mid and high doses.

Delayed sexual maturation and a neurological deficit (decreased motor coordination) were observed at the highest dose tested. The no-effect dose for adverse developmental effects (65 mg/kg/day) is less than the MRHD on a mg/m 2 basis. The rat data are of uncertain relevance to humans because of differences in metabolic profile between species.

8.2Lactation Eslicarbazepine is present in human milk. The effects of eslicarbazepine acetate tablets on the breastfed infant or on milk production are unknown. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for eslicarbazepine acetate tablets and any potential adverse effects on the breastfed infant from eslicarbazepine acetate tablets or from the underlying maternal condition.

8.5Geriatric Use There were insufficient numbers of patients ≥65 years old enrolled in the controlled adjunctive epilepsy trials (N=15) to determine the efficacy of eslicarbazepine acetate tablets in this patient population. The pharmacokinetics of eslicarbazepine acetate tablets were evaluated in elderly healthy subjects (N=12) (Figure 1). Although the pharmacokinetics of eslicarbazepine are not affected by age independently, dose selection should take in consideration the greater frequency of renal impairment and other concomitant medical conditions and drug therapies in the elderly patient.

Dose adjustment is necessary if CrCl is <50 mL/min [see Clinical Pharmacology (12.3) ].

8.6Patients with Renal Impairment Clearance of eslicarbazepine is decreased in patients with impaired renal function and is correlated with creatinine clearance. Dosage adjustment is necessary in patients with CrCl<50 mL/min (Figure 1) [see Dosage and Administration (2.4) and Clinical Pharmacology (12.3) ].

🆘 Overdosage 133 words ▾

10 OVERDOSAGE

10.1Signs, Symptoms, and Laboratory Findings of Acute Overdose in Humans Symptoms of overdose are consistent with the known adverse reactions of eslicarbazepine acetate tablets and include hyponatremia (sometimes severe), dizziness, nausea, vomiting, somnolence, euphoria, oral paraesthesia, ataxia, walking difficulties, and diplopia. The maximum dosage studied in open-label adult monotherapy treatment following withdrawal of concomitant AEDs was 2,400 mg once daily.

10.2Treatment or Management of Overdose There is no specific antidote for overdose with eslicarbazepine acetate tablets. Symptomatic and supportive treatment should be administered as appropriate. Removal of the drug by gastric lavage and/or inactivation by administering activated charcoal should be considered.

Standard hemodialysis procedures result in partial clearance of eslicarbazepine acetate tablets. Hemodialysis may be considered based on the patient's clinical state or in patients with significant renal impairment.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Eslicarbazepine acetate tablets are extensively converted to eslicarbazepine, which is considered to be responsible for therapeutic effects in humans. The precise mechanism(s) by which eslicarbazepine exerts anticonvulsant activity is unknown but is thought to involve inhibition of voltage-gated sodium channels.

12.2Pharmacodynamics The effect of eslicarbazepine acetate tablets on cardiac repolarization was evaluated in a randomized, double-blind, placebo- and active-controlled 4-period crossover trial in healthy adult men and women. Subjects received eslicarbazepine acetate tablets 1,200 mg once daily × 5 days, eslicarbazepine acetate tablets 2,400 mg once daily × 5 days, an active-control, moxifloxacin 400 mg × 1 dose on Day 5, and placebo once daily × 5 days. At both doses of eslicarbazepine acetate tablets, no significant effect on the QTc interval was detected.

12.3Pharmacokinetics The pharmacokinetics of eslicarbazepine is linear and dose-proportional in the dose range of 400 mg to 1,600 mg once daily, both in healthy adult subjects and patients. The apparent half-life of eslicarbazepine in plasma was 13-20 hours in adult epilepsy patients. Steady-state plasma concentrations are attained after 4 to 5 days of once daily dosing.

Absorption, Distribution, Metabolism, and Excretion Absorption Eslicarbazepine acetate tablets are mostly undetectable (0.01% of the systemic exposure) after oral administration. Eslicarbazepine, the major metabolite, is primarily responsible for the pharmacological effect of eslicarbazepine acetate tablets. Peak plasma concentrations (C max ) of eslicarbazepine are attained at 1-4 hours post-dose.

Eslicarbazepine is highly bioavailable, because the amount of eslicarbazepine and glucuronide metabolites recovered in urine corresponded to more than 90% of an eslicarbazepine acetate tablets dose. Food has no effect on the pharmacokinetics of eslicarbazepine after oral administration of eslicarbazepine acetate tablets. Distribution The binding of eslicarbazepine to plasma proteins is relatively low (<40%) and independent of concentration.

In vitro studies have shown that plasma protein binding was not relevantly affected by the presence of warfarin, diazepam, digoxin, phenytoin, or tolbutamide. Similarly, the binding of warfarin, diazepam, digoxin, phenytoin or tolbutamide was not significantly affected by the presence of eslicarbazepine. The apparent volume of distribution of eslicarbazepine is 61 L for body weight of 70 kg based on population PK analysis.

Metabolism Eslicarbazepine acetate tablets are rapidly and extensively metabolized to its major active metabolite eslicarbazepine by hydrolytic first-pass metabolism. Eslicarbazepine corresponds to 91% of systemic exposure. The systemic exposure to minor active metabolites of (R)-licarbazepine is 5% and oxcarbazepine is 1%.

The inactive glucuronides of these active metabolites correspond to approximately 3% of systemic exposure. In in vitro studies in human liver microsomes, eslicarbazepine had no clinically relevant inhibitory effect on the activity of CYP1A2, CYP2A6, CYP2B6, CYP2D6, CYP2E1, and CYP3A4, and only a moderate inhibitory effect on CYP2C19. Studies with eslicarbazepine in fresh human hepatocytes showed no induction of enzymes involved in glucuronidation and sulfation of 7-hydroxy-coumarin.

A mild activation of UGT1A1-mediated glucuronidation was observed in human hepatic microsomes. No apparent autoinduction of metabolism has been observed with eslicarbazepine acetate tablets in humans. Excretion Eslicarbazepine acetate tablets metabolites are eliminated from the systemic circulation primarily by renal excretion, in the unchanged and glucuronide conjugate forms.

In total, eslicarbazepine and its glucuronide account for more than 90% of total metabolites excreted in urine, approximately two thirds in the unchanged form and one third as glucuronide conjugate. Other minor metabolites acco… [Excerpted — this section continues on DailyMed.]

MEDICATION GUIDE Eslicarbazepine Acetate Tablets (es’’ li kar baz’ e peen as’ e tate) What is the most important information I should know about eslicarbazepine acetate tablets? Do not stop taking eslicarbazepine acetate tablets without first talking to your healthcare provider. Stopping eslicarbazepine acetate tablets suddenly can cause serious problems.

Stopping a seizure medicine suddenly in a patient who has epilepsy may cause seizures that will not stop (status epilepticus). 1. Like other antiepileptic drugs, eslicarbazepine acetate tablets may cause suicidal thoughts or actions in a very small number of people, about 1 in 500.

Call a healthcare provider right away if you have any of these symptoms, especially if they are new, worse, or worry you: o thoughts about suicide or dying o attempt to commit suicide o new or worse depression o new or worse anxiety o feeling agitated or restless o panic attacks o trouble sleeping (insomnia) o new or worse irritability o acting aggressive, being angry, or violent o acting on dangerous impulses o an extreme increase in activity and talking (mania) o other unusual changes in behavior or mood How can I watch for early symptoms of suicidal thoughts and actions?

Pay attention to any changes, especially sudden changes, in mood, behaviors, thoughts, or feelings. Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you are worried about symptoms.

Suicidal thoughts or actions may be caused by things other than medicines. If you have suicidal thoughts or actions, your healthcare provider may check for other causes. 2.

Eslicarbazepine acetate tablets may cause allergic reactions or serious problems which may affect organs and other parts of your body like the liver or blood cells. You may or may not have a rash with these types of reactions. Call your healthcare provider right away if you have any of the following: ○ swelling of your face, eyes, lips, or tongue ○ trouble swallowing or breathing ○ a skin rash ○ hives ○ fever, swollen glands, or sore throat that do not go away or come and go ○ painful sores in the mouth or around your eyes ○ yellowing of your skin or eyes ○ unusual bruising or bleeding ○ severe fatigue or weakness ○ severe muscle pain ○ frequent infections or infections that do not go away Eslicarbazepine acetate tablets may cause the level of sodium in your blood to be low.

Symptoms of low blood sodium include: o nausea o tiredness, lack of energy o irritability o confusion o muscle weakness or muscle spasms o more frequent or more severe seizures Some medicines can also cause low sodium in your blood. Be sure to tell your healthcare provider about all the other medicines that you are taking. What are eslicarbazepine acetate tablets?

14 CLINICAL STUDIES

14.1Monotherapy for Partial-Onset Seizures The effectiveness of eslicarbazepine acetate tablets as monotherapy for partial-onset seizures was established in two identical, dose-blinded historical control trials in a total of 365 patients with epilepsy (Study 1 and Study 2). In these trials, patients were randomized in a 2:1 ratio to receive either eslicarbazepine acetate tablets 1,600 mg or 1,200 mg once daily, and their responses were compared to those of a historical control group. The historical control methodology is described in a publication by French et al. [see References (15) ] .

The historical control consisted of a pooled analysis of the control groups from 8 trials of similar design, which utilized a subtherapeutic dose of an AED as a comparator. Statistical superiority to the historical control was considered to be demonstrated if the upper limit from a 2-sided 95% confidence interval for the percentage of patients meeting exit criteria in patients receiving eslicarbazepine acetate tablets remained below the lower 95% prediction interval of 65% derived from the historical control data. In Study 1 and Study 2, patients ≥16 years of age experienced at least 4 seizures during the baseline period with no 28-day seizure free period while receiving 1 or 2 AEDs (both could not be sodium-channel blocking drugs, and at least one AED was limited to 2/3 of a typical dose).

Eslicarbazepine acetate tablets was titrated over a 1- to 2-week period followed by the gradual withdrawal of the background AED over a 6-week period, followed by a 10-week monotherapy period. The exit criteria were one or more of the following: (1) an episode of status epilepticus, (2) emergence of a generalized tonic-clonic seizure in patients who had not had one in the past 6 months, (3) doubling of average monthly seizure count during any 28 consecutive days, (4) doubling of highest consecutive 2-day seizure frequency during the entire treatment phase, or (5) worsening of seizure severity considered by the investigator to require intervention.

The primary endpoint was the cumulative 112-day exit rate in the efficacy population. Additionally, in Studies 1 and 2, if the discontinuation rate exceeded 10%, patients were randomly reassigned to be counted as exits. The most commonly used baseline AEDs were carbamazepine, levetiracetam, valproic acid, and lamotrigine.

Oxcarbazepine was used as a baseline AED in 6.6% of patients. In Study 1, the Kaplan-Meier (K-M) estimate of the percentage of patients meeting at least 1 exit criterion was 29% (95% CI: 21%, 38%) in the 1,600 mg group and 44% (95% CI 33%, 58%) in the 1,200 mg group. In Study 2, the K-M estimate of the percentage of patients meeting at least 1 exit criterion was 13% (95% CI: 8%, 22%) in the 1,600 mg group and 16% (95% CI: 8%, 29%) in the 1,200 mg group.

The upper limit of the 2-sided 95% CI of both doses in both trials were below the threshold of 65% derived from the historical control data, meeting the pre-specified criteria for efficacy (see Figure 4). Figure 4: Kaplan-Meier Estimates of Cumulative 112-Day Exit Rates for Studies 1 and 2 figure04

14.2Adjunctive Therapy for Partial-Onset Seizures The efficacy of eslicarbazepine acetate tablets as adjunctive therapy in partial-onset seizures was established in three randomized, double-blind, placebo-controlled, multicenter trials in adult patients with epilepsy (Study 3, Study 4, and Study 5). Patients enrolled had partial-onset seizures with or without secondary generalization and were not adequately controlled with 1 to 3 concomitant AEDs. During an 8-week baseline period, patients were required to have an average of ≥4 partial-onset seizures per 28 days with no seizure-free period exceeding 21 days.

In these three trials, patients had a median duration of epilepsy of 19 years and a median baseline seizure frequency of 8 seizures per 28 days. Two-thirds (69%) of subjects used 2 concomitant AEDs and 28% used 1 concomitant A… [Excerpted — this section continues on DailyMed.]

🔒 Drug Abuse and Dependence ~1 min read ▾

9 DRUG ABUSE AND DEPENDENCE

9.1Controlled Substance Eslicarbazepine acetate tablets are not a controlled substance.

9.2Abuse Prescription drug abuse is the intentional non-therapeutic use of a drug, even once, for its rewarding psychological or physiological effects. Drug addiction, which develops after repeated drug abuse, is characterized by a strong desire to take a drug despite harmful consequences, difficulty in controlling its use, giving a higher priority to drug use than to obligations, increased tolerance, and sometimes physical withdrawal. Drug abuse and drug addiction are separate and distinct from physical dependence (for example, abuse may not be accompanied by physical dependence) [see Drug Abuse and Dependence (9.3) ].

In a human abuse study in recreational sedative abusers eslicarbazepine acetate tablets showed no evidence of abuse. In Phase 1, 1.5% of the healthy volunteers taking eslicarbazepine acetate tablets reported euphoria compared to 0.4% taking placebo.

9.3Dependence Physical dependence is characterized by withdrawal symptoms after abrupt discontinuation or a significant dose reduction of a drug. There was some evidence of physical dependence or a withdrawal syndrome with eslicarbazepine acetate tablets in a physical dependence study conducted in healthy volunteers who were maintained at a daily dose of 800 mg eslicarbazepine acetate tablets for 4 weeks prior to discontinuation. The primary endpoint was the maximum change from steady-state baseline in the total score of the Physician’s Withdrawal Checklist (PWC-34) during the 21-day discontinuation period.

Eslicarbazepine acetate tablets and placebo were shown to be equivalent on the primary endpoint. Two out of 8 secondary endpoints (visual analog scales for anxiety and nausea) showed some increase in these symptoms for subjects who were maintained on eslicarbazepine acetate tablets and discontinued, versus subjects who were maintained on placebo. In general, AEDs should not be abruptly discontinued in patients with epilepsy because of the risk of increased seizure frequency and status epilepticus.

13 NONCLINICAL TOXICOLOGY

13.1Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis In a two-year carcinogenicity study in mice, eslicarbazepine acetate was administered orally at doses of 100, 250, and 600 mg/kg/day. An increase in the incidence of hepatocellular adenomas and carcinomas was observed at 250 and 600 mg/kg/day in males and at 600 mg/kg/day in females. The dose not associated with an increase in tumors (100 mg/kg/day) is less than the MRHD (1,600 mg/day for monotherapy) on a mg/m 2 basis.

Mutagenesis Eslicarbazepine acetate and eslicarbazepine were not mutagenic in the in vitro Ames assay. In in vitro assays in mammalian cells, eslicarbazepine acetate and eslicarbazepine were not clastogenic in human peripheral blood lymphocytes; however, eslicarbazepine acetate was clastogenic in Chinese hamster ovary (CHO) cells, with and without metabolic activation. Eslicarbazepine acetate was positive in the in vitro mouse lymphoma tk assay in the absence of metabolic activation.

Eslicarbazepine acetate was not clastogenic in the in vivo mouse micronucleus assay. Impairment of Fertility When eslicarbazepine acetate (150, 350, and 650 mg/kg/day) was orally administered to male and female mice prior to and throughout the mating period, and continuing in females to gestation day 6, there was an increase in embryolethality at all doses. The lowest dose tested is less than the MRHD on a mg/m 2 basis.

When eslicarbazepine acetate (65, 125, 250 mg/kg/day) was orally administered to male and female rats prior to and throughout the mating period, and continuing in females to implantation, lengthening of the estrus cycle was observed at the highest dose tested. The data in rats are of uncertain relevance to humans because of differences in metabolic profile between species.

The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The form printed on the packaging and shown on DailyMed is the one the FDA registered. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero and the dashes are dropped. The Identity section at the top of this page lists each form of this code.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Jubilant Cadista Pharmaceuticals Inc.. Listing status can change — the directory data on this page refreshes weekly.
Does this product come in other package sizes?
Yes — the FDA directory lists 2 other package presentations of this same product, including 30 tablets (59746-0720-30), 90 tablets (59746-0720-90). Each has its own NDC and its own page — see the package list near the top of this page.
