Why two NDCs? The FDA registers this code as 76494-529-12 — a 5-3-2 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the product segment → 76494-0529-12. Same drug, same package — only the format differs.

16 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMedingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 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.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.

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.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Levetiracetam — the program that covers self-administered drugs. 30 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Levetiracetam. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

Questions about this listing

Why is there no price listed?
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 FDA registers it as 76494-529-12, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 76494-0529-12, written without dashes as 76494052912. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 76494-0529-12, the first segment (76494) is the labeler code FDA assigned to Prinston Pharmaceutical Inc.; the middle segment (0529) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (12) identifies this exact package size and type. Together they name one specific package of one specific product.
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 Prinston Pharmaceutical Inc.. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Prinston Pharmaceutical Inc. is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

🎯 Indications and Usage ~1 min read

1 INDICATIONS AND USAGE Levetiracetam is an antiepileptic drug indicated for adjunctive therapy in the treatment of: • Partial onset seizures in patients four years of age and older with epilepsy ( 1.1 ) • Myoclonic seizures in patients 12 years of age and older with juvenile myoclonic epilepsy ( 1.2 ) • Primary generalized tonic-clonic seizures in patients 6 years of age and older with idiopathic generalized epilepsy ( 1.3 )

1.1Partial Onset Seizures Levetiracetam is indicated as adjunctive therapy in the treatment of partial onset seizures in adults and children four years of age and older with epilepsy. Information describing the use of levetiracetam in pediatric patients less than 4 years of age as adjunctive therapy in the treatment of partial onset seizures is approved for UCB, Inc.’s levetiracetam tablets and oral solution. However, due to UCB, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

1.2Myoclonic Seizures in Patients with Juvenile Myoclonic Epilepsy Levetiracetam is indicated as adjunctive therapy in the treatment of myoclonic seizures in adults and adolescents 12 years of age and older with juvenile myoclonic epilepsy.

1.3Primary Generalized Tonic-Clonic Seizures Levetiracetam is indicated as adjunctive therapy in the treatment of primary generalized tonic-clonic seizures in adults and children 6 years of age and older with idiopathic generalized epilepsy.

⏱️ Dosage and Administration ~3 min read

2 DOSAGE AND ADMINISTRATION Partial Onset Seizures • 4 Years to < 16 Years: 10 mg/kg twice daily, increase in increments of 10 mg/kg twice daily every 2 weeks to recommended dose of 30 mg/kg twice daily ( 2.2 ) • Adults 16 Years and Older: 500 mg twice daily, increase as needed and tolerated in increments of 500 mg twice daily every 2 weeks to a maximum recommended dose of 1500 mg twice daily ( 2.2 ) Myoclonic Seizures in Adults and Pediatric Patients 12 Years and Older • 500 mg twice daily, increase by 500 mg twice daily every 2 weeks to recommended dose of 1500 mg twice daily ( 2.3 ) Primary Generalized Tonic-Clonic Seizures • 6 Years to < 16 Years: 10 mg/kg twice daily, increase in increments of 10 mg/kg twice daily every 2 weeks to recommended dose of 30 mg/kg twice daily ( 2.4 ) • Adults 16 Years and Older: 500 mg twice daily, increase by 500 mg twice daily every 2 weeks to recommended dose of 1500 mg twice daily ( 2.4 ) Adult Patients with Impaired Renal Function • Dose adjustment is recommended, based on the patient’s estimated creatinine clearance ( 2.5 , 8.6 )

2.1Important Administration Instructions Levetiracetam is given orally with or without food. The Levetiracetam dosing regimen depends on the indication, age group, dosage form (tablets), and renal function. Levetiracetam tablets should be swallowed whole. Levetiracetam tablets should not be chewed or crushed.

2.2Partial Onset Seizures Adults 16 Years and Older In clinical trials, daily doses of 1000 mg, 2000 mg, and 3000 mg, given as twice-daily dosing were shown to be effective. Although in some studies there was a tendency toward greater response with higher dose [see Clinical Studies (14.1) ] , a consistent increase in response with increased dose has not been shown. Treatment should be initiated with a daily dose of 1000 mg/day, given as twice-daily dosing (500 mg twice daily).

Additional dosing increments may be given (1000 mg/day additional every 2 weeks) to a maximum recommended daily dose of 3000 mg. Doses greater than 3000 mg/day have been used in open-label studies for periods of 6 months and longer. There is no evidence that doses greater than 3000 mg/day confer additional benefit.

Pediatric Patients Dosing information in pediatric patients less than 4 years of age as adjunctive therapy in the treatment of partial onset seizures is approved for UCB, Inc.’s levetiracetam tablets and oral solution. However, due to UCB, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information. 4 Years to < 16 Years Treatment should be initiated with a daily dose of 20 mg/kg in 2 divided doses (10 mg/kg twice daily).

5 WARNINGS AND PRECAUTIONS • Psychiatric Symptoms: Behavioral abnormalities including psychotic symptoms, suicidal ideation, irritability, and aggressive behavior have been observed. Monitor patients for psychiatric signs and symptoms ( 5.1 ) • Suicidal Behavior and Ideation: Monitor patients for new or worsening depression, suicidal thoughts/behavior, and/or unusual changes in mood or behavior ( 5.2 ) • Somnolence and Fatigue: Monitor patients for these symptoms and advise patients not to drive or operate machinery until they have gained sufficient experience on Levetiracetam ( 5.3 ) • Withdrawal Seizures: Levetiracetam must be gradually withdrawn ( 5.6 )

5.1Psychiatric Reactions In some patients Levetiracetam causes behavioral abnormalities. The incidences of behavioral abnormalities in the myoclonic and primary generalized tonic-clonic seizure studies were comparable to those of the adult and pediatric partial onset seizure studies. A total of 13.3% of adult Levetiracetam-treated patients and 37.6% of pediatric Levetiracetam-Treated patients (4 to 16 years of age) compared to 6.2% and 18.6% of adult and pediatric placebo patients respectively, experienced non-psychotic behavioral symptoms (reported as aggression, agitation, anger, anxiety, apathy, depersonalization, depression, emotional lability, hostility, hyperkinesias, irritability, nervousness, neurosis, and personality disorder).

A randomized double-blind, placebo-controlled study was performed to assess the neurocognitive and behavioral effects of Levetiracetam as adjunctive therapy in pediatric patients (4 to 16 years of age). The results from an exploratory analysis indicated a worsening in Levetiracetam-Treated patients on aggressive behavior (one of eight behavior dimensions) as measured in a standardized and systematic way using a validated instrument, the Achenbach Child Behavior Checklist (CBCL/6-18). In pediatric patients 1 month to < 4 years of age, irritability was reported in 11.7% of the Levetiracetam-Treated patients compared to 0% of placebo patients.

A total of 1.7% of adult Levetiracetam-treated patients discontinued treatment due to behavioral adverse events, compared to 0.2% of placebo patients. The treatment dose was reduced in 0.8% of adult Levetiracetam-Treated patients and in 0.5% of placebo patients. Overall, 10.9% of Levetiracetam-Treated pediatric patients experienced behavioral symptoms associated with discontinuation or dose reduction, compared to 6.2% of placebo patients.

One percent of adult Levetiracetam-Treated patients, 2% of children 4 to 16 years of age, and 17% of children 1 month to <4 years of age experienced psychotic symptoms, compared to 0.2%, 2%, and 5% respectively, in the placebo patients. In the controlled study that assessed the neurocognitive and behavioral effects of Levetiracetam in pediatric patients 4 to 16 years of age, 1 (1.6%) Levetiracetam-Treated patient experienced paranoia compared to no placebo patients. There were 2 (3.1%) Levetiracetam-Treated patients that experienced confusional state compared to no placebo patients [see Use in Specific Populations (8.4) ] .

Two (0.3%) adult Levetiracetam-Treated patients were hospitalized and their treatment was discontinued due to psychosis. Both events, reported as psychosis, developed within the first week of treatment and resolved within 1 to 2 weeks following treatment discontinuation. There was no difference between drug and placebo-treated patients in the incidence of the pediatric patients who discontinued treatment due to psychotic and non-psychotic adverse reactions.

The above psychiatric signs and symptoms should be monitored.

5.2Suicidal Behavior and Ideation Antiepileptic drugs (AEDs), including Levetiracetam, 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…

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. The prescriber should be aware that the adverse reaction incidence figures in the following tables, obtained when Levetiracetam was added to concurrent AED therapy, cannot be used to predict the frequency of adverse reactions in the course of usual medical practice where patient characteristics and other factors may differ from those prevailing during clinical trials.

Similarly, the cited frequencies cannot be directly compared with figures obtained from other clinical investigations involving different treatments, uses, or investigators. An inspection of these frequencies, however, does provide the prescriber with one basis to estimate the relative contribution of drug and non-drug factors to the adverse reaction incidences in the population studied. Partial Onset Seizures Adults In controlled clinical studies in adults with partial onset seizures, the most frequently reported adverse reactions in patients receiving Levetiracetam in combination with other AEDs, for events with rates greater than placebo, were somnolence, asthenia, infection and dizziness.

Of the most frequently reported adverse reactions in adults experiencing partial onset seizures, asthenia, somnolence and dizziness appeared to occur predominantly during the first 4 weeks of treatment with Levetiracetam. Table 3 lists adverse reactions that occurred in at least 1% of adult epilepsy patients treated with Levetiracetam participating in placebo-controlled studies and were numerically more common than in patients treated with placebo. In these studies, either Levetiracetam or placebo was added to concurrent AED therapy.

Adverse reactions were usually mild to moderate in intensity.

👥 Use in Specific Populations ~3 min read

8 USE IN SPECIFIC POPULATIONS • Pregnancy: Plasma levels of levetiracetam may be decreased and therefore need to be monitored closely during pregnancy. Based on animal data, may cause fetal harm ( 5.9 , 8.1 ) Information describing the use of levetiracetam tablets and levetiracetam oral solution in pediatric patients less than 4 years of age as adjunctive therapy in the treatment of partial onset seizures is approved for UCB, Inc.’s levetiracetam tablets and oral solution. However, due to UCB Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information.

8.1Pregnancy Levetiracetam levels may decrease during pregnancy [see Warnings and Precautions (5.9) ]. Pregnancy Category C There are no adequate and well-controlled studies in pregnant women. In animal studies, levetiracetam produced evidence of developmental toxicity, including teratogenic effects, at doses similar to or greater than human therapeutic doses.

Levetiracetam should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Oral administration of levetiracetam to female rats throughout pregnancy and lactation led to increased incidences of minor fetal skeletal abnormalities and retarded offspring growth pre- and/or postnatally at doses ≥350 mg/kg/day (equivalent to the maximum recommended human dose of 3000 mg [MRHD] on a mg/m 2 basis) and with increased pup mortality and offspring behavioral alterations at a dose of 1800 mg/kg/day (6 times the MRHD on a mg/m 2 basis).

The developmental no effect dose was 70 mg/kg/day (0.2 times the MRHD on a mg/m 2 basis). There was no overt maternal toxicity at the doses used in this study. Oral administration of levetiracetam to pregnant rabbits during the period of organogenesis resulted in increased embryofetal mortality and increased incidences of minor fetal skeletal abnormalities at doses ≥600 mg/kg/day (4 times MRHD on a mg/m 2 basis) and in decreased fetal weights and increased incidences of fetal malformations at a dose of 1800 mg/kg/day (12 times the MRHD on a mg/m 2 basis).

The developmental no effect dose was 200 mg/kg/day (equivalent to the MRHD on a mg/m 2 basis). Maternal toxicity was also observed at 1800 mg/kg/day. When levetiracetam was administered orally to pregnant rats during the period of organogenesis, fetal weights were decreased and the incidence of fetal skeletal variations was increased at a dose of 3600 mg/kg/day (12 times the MRHD).

1200 mg/kg/day (4 times the MRHD) was a developmental no effect dose. There was no evidence of maternal toxicity in this study. Treatment of rats with levetiracetam during the last third of gestation and throughout lactation produced no adverse developmental or maternal effects at doses of up to 1800 mg/kg/day (6 times the MRHD on a mg/m 2 basis).

Pregnancy Registries To provide information regarding the effects of in utero exposure to Levetiracetam, physicians are advised to recommend that pregnant patients taking Levetiracetam enroll in the North American Antiepileptic Drug (NAAED) pregnancy registry. This can be done by calling the toll free number 1-888-233-2334, and must be done by the patients themselves. Information on the registry can also be found at the website http://www.aedpregnancyregistry.org/.

8.2Labor and Delivery The effect of Levetiracetam on labor and delivery in humans is unknown.

8.3Nursing Mothers Levetiracetam is excreted in human milk. Because of the potential for serious adverse reactions in nursing infants from Levetiracetam, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.

🧒 Pediatric Use ~2 min read

8.4Pediatric Use The safety and effectiveness of Levetiracetam in the adjunctive treatment of partial onset seizures in pediatric patients age 4 years to 16 years old with epilepsy have been established [see Clinical Studies (14.1) ] . The dosing recommendation in these pediatric patients varies according to age group and is weight-based [see Dosage and Administration (2.2) ]. Pediatric use information in pediatric patients less than 4 years of age as adjunctive therapy in the treatment of partial onset seizures is approved for UCB, Inc.’s levetiracetam tablets and oral solution.

However, due to UCB, Inc.’s marketing exclusivity rights, this drug product is not labeled with that pediatric information. The safety and effectiveness of Levetiracetam as adjunctive treatment of myoclonic seizures in adolescents 12 years of age and older with juvenile myoclonic epilepsy have been established [ see Clinical Studies (14.2) ]. The safety and effectiveness of Levetiracetam as adjunctive therapy in the treatment of primary generalized tonic-clonic seizures in pediatric patients 6 years of age and older with idiopathic generalized epilepsy have been established [see Clinical Studies (14.3) ].

A 3-month, randomized, double-blind, placebo-controlled study was performed to assess the neurocognitive and behavioral effects of Levetiracetam as adjunctive therapy in 98 (Levetiracetam N=64, placebo N=34) pediatric patients, ages 4 to 16 years old, with partial seizures that were inadequately controlled. The target dose was 60 mg/kg/day. Neurocognitive effects were measured by the Leiter-R Attention and Memory (AM) Battery, which measures various aspects of a child's memory and attention.

Although no substantive differences were observed between the placebo and drug treated groups in the median change from baseline in this battery, the study was not adequate to assess formal statistical non-inferiority of the drug and placebo. The Achenbach Child Behavior Checklist (CBCL/6-18), a standardized validated tool used to assess a child’s competencies and behavioral/emotional problems, was also assessed in this study. An analysis of the CBCL/6-18 indicated on average a worsening in Levetiracetam-Treated patients in aggressive behavior, one of the eight syndrome scores [see Warnings and Precautions (5.1) ] .

Studies of levetiracetam in juvenile rats (dosing from day 4 through day 52 of age) and dogs (dosing from week 3 through week 7 of age) at doses of up to 1800 mg/kg/day (approximately 7 and 24 times, respectively, the maximum recommended pediatric dose of 60 mg/kg/day on a mg/m 2 basis) did not indicate a potential for age-specific toxicity.

🧓 Geriatric Use 112 words

8.5Geriatric Use There were 347 subjects in clinical studies of levetiracetam that were 65 and over. No overall differences in safety were observed between these subjects and younger subjects. There were insufficient numbers of elderly subjects in controlled trials of epilepsy to adequately assess the effectiveness of Levetiracetam in these patients.

Levetiracetam is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function [see Clinical Pharmacology (12.3) ].

🆘 Overdosage 195 words

10 OVERDOSAGE

10.1Signs, Symptoms and Laboratory Findings of Acute Overdosage in Humans The highest known dose of Levetiracetam received in the clinical development program was 6000 mg/day. Other than drowsiness, there were no adverse events in the few known cases of overdose in clinical trials. Cases of somnolence, agitation, aggression, depressed level of consciousness, respiratory depression and coma were observed with Levetiracetam overdoses in postmarketing use.

10.2Management of Overdose There is no specific antidote for overdose with Levetiracetam. If indicated, elimination of unabsorbed drug should be attempted by emesis or gastric lavage; usual precautions should be observed to maintain airway. General supportive care of the patient is indicated including monitoring of vital signs and observation of the patient’s clinical status.

A Certified Poison Control Center should be contacted for up to date information on the management of overdose with Levetiracetam.

10.3Hemodialysis Standard hemodialysis procedures result in significant clearance of levetiracetam (approximately 50% in 4 hours) and should be considered in cases of overdose. Although hemodialysis has not been performed in the few known cases of overdose, it may be indicated by the patient's clinical state or in patients with significant renal impairment.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The precise mechanism(s) by which levetiracetam exerts its antiepileptic effect is unknown. The antiepileptic activity of levetiracetam was assessed in a number of animal models of epileptic seizures. Levetiracetam did not inhibit single seizures induced by maximal stimulation with electrical current or different chemoconvulsants and showed only minimal activity in submaximal stimulation and in threshold tests.

Protection was observed, however, against secondarily generalized activity from focal seizures induced by pilocarpine and kainic acid, two chemoconvulsants that induce seizures that mimic some features of human complex partial seizures with secondary generalization. Levetiracetam also displayed inhibitory properties in the kindling model in rats, another model of human complex partial seizures, both during kindling development and in the fully kindled state. The predictive value of these animal models for specific types of human epilepsy is uncertain.

In vitro and in vivo recordings of epileptiform activity from the hippocampus have shown that levetiracetam inhibits burst firing without affecting normal neuronal excitability, suggesting that levetiracetam may selectively prevent hypersynchronization of epileptiform burst firing and propagation of seizure activity. Levetiracetam at concentrations of up to 10 μM did not demonstrate binding affinity for a variety of known receptors, such as those associated with benzodiazepines, GABA (gamma-aminobutyric acid), glycine, NMDA (N-methyl-D-aspartate), re-uptake sites, and second messenger systems.

Furthermore, in vitro studies have failed to find an effect of levetiracetam on neuronal voltage-gated sodium or T-type calcium currents and levetiracetam does not appear to directly facilitate GABAergic neurotransmission. However, in vitro studies have demonstrated that levetiracetam opposes the activity of negative modulators of GABA- and glycine-gated currents and partially inhibits N-type calcium currents in neuronal cells. A saturable and stereoselective neuronal binding site in rat brain tissue has been described for levetiracetam.

Experimental data indicate that this binding site is the synaptic vesicle protein SV2A, thought to be involved in the regulation of vesicle exocytosis. Although the molecular significance of levetiracetam binding to SV2A is not understood, levetiracetam and related analogs showed a rank order of affinity for SV2A which correlated with the potency of their antiseizure activity in audiogenic seizure-prone mice. These findings suggest that the interaction of levetiracetam with the SV2A protein may contribute to the antiepileptic mechanism of action of the drug.

12.2Pharmacodynamics Effects on QTc Interval The effect of Levetiracetam on QTc prolongation was evaluated in a randomized, double-blind, positive-controlled (moxifloxacin 400 mg) and placebo-controlled crossover study of Levetiracetam (1000 mg or 5000 mg) in 52 healthy subjects. The upper bound of the 90% confidence interval for the largest placebo-adjusted, baseline-corrected QTc was below 10 milliseconds. Therefore, there was no evidence of significant QTc prolongation in this study.

12.3Pharmacokinetics Absorption and Distribution Absorption of levetiracetam is rapid, with peak plasma concentrations occurring in about an hour following oral administration in fasted subjects. The oral bioavailability of levetiracetam tablets is 100% and the tablets and oral solution are bioequivalent in rate and extent of absorption. Food does not affect the extent of absorption of levetiracetam but it decreases C max by 20% and delays T max by 1.5 hours.

The pharmacokinetics of levetiracetam are linear over the dose range of 500-5000 mg. Steady state is achieved after 2 days of multiple twice-daily dosing. Levetiracetam and its major metabolite are less than 10% bound to plasma proteins; clinically significant interactions with other drugs through competitio…
