General | Latest Info

Levetiracetam is an oral medication that is indicated for management of refractory epilepsy. All seizure control medications have the potential to cause drowsiness. Some cats lose their appetites temporarily when beginning levetiracetam. Levetiracetam should not be used in pets who have previously exhibited hypersensitivity to it or any of its components. It should be used with caution in pets with renal impairment; dosing amounts or dosing frequency changes should be consider. This medication has been shown to cause increased fetal and embryonal losses, and should only be used in pregnant animals when benefits outweigh risks. Pets with decreased kidney function should use this medication with caution. When discontinuing use of this medication, gradual withdrawal is recommended to help prevent the likelihood of seizure-withdrawals. This drug is FDA-approve for human use. However, it is common practice for veterinarians to prescribe such drugs for use in dogs and cats. Levetiracetam extend Release is an anti-epileptic drug used in management of refractory epilepsy in cats and dogs. Use as an add-on drug for dogs and cats whose seizures are not adequately controlled by phenobarbital or bromides. It can be used to treat seizures due to hepatic encephalopathy or cases of phenobarbital-induce liver damage. Levetiracetam extend Release is in the class of medications Call anticonvulsants. It works by decreasing abnormal excitement in the brain. Our lab was only 1. He was 5 years old when he started having seizures, and we were reluctant to give him phenobarbital because of the terrible side effects, so we started with Keppra and it has been a life saver. He went 5 months without seizure on 500mg tablets and then when he had 3 one month apart we up him to 750mg tablets and were almost 8 weeks and counting! No side effects at all and well tolerate. I am so thankful that chewy has it for so much cheaper than neurologist!

Introduction

Epilepsy is a chronic condition characterized by recurrent unprovoked epileptic seizures. 1 It affect 0. 5 %-1 % of the population and at least 50 % of patients with epilepsy have partial seizures. About 30 %-70 % of partial seizures are controllable with antiepileptic drugs. The majority of these patients will need lifelong AED therapy. Strict AED compliance is often related to better tolerability and is a key factor in achieving better seizure control. An inverse relationship between the number of daily doses and compliance has been report. Every increase in dosing frequency results in progressively worsening compliance and increase miss doses. 2-4 Conceptually, stable Plasma concentration profile of Extended release AED formulations is expected to minimize peak concentration-related adverse events and improve compliance and seizure control. 5 6 extend release formulations may contribute to better tolerability and improved efficacy. 6 Extended release levetiracetam was developed to provide patients with convenience of once-daily dosing, potentially improving compliance and efficacy-tolerability ratio. It shows that the pharmacokinetic profile for LEV-XR is comparable to immediate release levetiracetam. 6 7 While both LEV-XR and LEV-IR formulations may cause similar side effects that are generally well-tolerate, LEV-XR is usually preferred for its ease of use and more stable serum drug levels, both increasing patient compliance. Ease of conversion between LEV formulations also makes the LEV-XR attractive option.

Pharmacokinetic profile

Metabolism of levetiracetam is independent of the hepatic cytochrome P450 system. Sixty-six percent of the administered dose of levetiracetam is excrete unchanged in urine, and 27 % is excrete as inactive metabolites. 24 major metabolic pathways involve enzymatic hydrolysis of the acetamide group, which results in one major inactive carboxylic acid metabolite. 23 levetiracetam is rapidly clear, with about 93 % of give dose excrete within 48 hours of oral administration. The rate of renal clearance is 0. 6 ML / min / kg. Levetiracetams Plasma Half-life in healthy subjects is approximately 6 to 8 hours. 23 Half-life and apparent clearance of both levetiracetam IR and XR are dose-independent. 5 mechanism of excretion is through glomerular filtration, followed by partial tubular reabsorption. The major metabolite, L057, is excrete by glomerular filtration and active tubular secretion with renal clearance of 4 ML / min / kg. 23 rate of elimination of levetiracetam is dependent on creatinine clearance; therefore, dose adjustments are required in patients with renal impairment. 22 Plasma elimination Half-life of levetiracetam IR in elderly subjects increased to between 10 and 11 hours. 24 This is likely due to an age-related decrease in creatinine clearance, which may require a decrease in daily dose. Pharmacokinetics of levetiracetam IR were studied in 16 patients with varying degrees of liver cirrhosis. 25 Patients with mild to moderate hepatic dysfunction require no adjustment of levetiracetam dose. However, those with severe cirrhosis and concomitant renal insufficiency may require lower levetiracetam dose.

Clinical efficacy

Initial approval of Levetiracetam for adjunctive treatment of partial-onset seizures in adults is based on results of 3 double-blind, randomize, placebo-control, multicenter trials. The 2-4 American trial by Cereghino et al looked at the efficacy and tolerability of 500mg bid and 1500 mg bid of Levetiracetam as add-on therapy in patients 16 to 70 years of age with partial-onset seizures refractory to at least 2 AEDs. 3 Study consists of a 12-week placebo baseline period, 4-week drug uptitration period, and a 14-week treatment / evaluation period. Two hundred ninety-four patients were randomize: 98 to Levetiracetam 1000 mg / day, 101 to Levetiracetam 3000 mg / day and 95 to placebo. The median percent reduction in seizure frequency from baseline was 32. 5 % with Levetiracetam 1000 mg / day, 37. 1 % with Levetiracetam 3000mg / day, and 6. 8 % with placebo. The median percent reduction in seizure frequency over placebo was 20. 9 % with Levetiracetam 1000mg / day and 27. 7 % with Levetiracetam 3000mg / day. Responder rate was 33 % with Levetiracetam 1000 mg / day, 39. 8 % with Levetiracetam 3000 mg / day, and 10. 8 % with placebo. Eight patients in the Levetiracetam 3000 mg / day Group were Seizure-free during the entire 14-week evaluation period compared to none in the placebo Group. In one European trial by Shorvon et al, efficacy and tolerability of 500 mg bid and 1000 mg bid of Levetiracetam as add-on therapy in patients 16 to 65 years of age with partial-onset seizures refractory to 1 to 2 AEDs was assess. 4 Study consists of an 8-week baseline period, 4-week uptitration period, and a 12-week treatment / evaluation period. Three hundred twenty-four patients were randomize: 112 in the placebo Group, 106 in the Levetiracetam 1000 mg / day Group, and 106 in the Levetiracetam 2000mg / day Group. The median percent reduction in weekly seizure frequency from baseline was 17. 7 % with Levetiracetam 1000 mg / day, 26. 5 % with Levetiracetam 2000 mg / day, and 6. 1 % with placebo. The median percent reduction in seizure frequency over placebo was 16. 4 % with Levetiracetam 1000mg / day and 17. 7 % with Levetiracetam 2000 mg / day. Responder rate was 22. 8 % with Levetiracetam 1000mg / day, 31. 6 % with Levetiracetam 2000mg / day, and 10. 4 % with placebo. In another European trial by Ben-Menachem and Falter, efficacy and tolerability of Levetiracetam 3000 mg / day as add-on therapy in patients 16 to 70 years of age with partial-onset seizures was assess. 2 Study consists of a 12-week baseline period, 4-week up-titration period, 14-week add-on evaluation period, and a monotherapy phase that includes a maximum of 12 weeks of down-titration of concomitant AED and 12 weeks of monotherapy with Levetiracetam 3000mg / day. The primary efficacy variable was the percentage of patients who completed the monotherapy phase. Two hundred eighty-six patients were randomize: 181 to Levetiracetam 3000mg / day and 105 to placebo. Of this intention-to-treat population, 19. 9 % of patients in the Levetiracetam Group completed study in comparison to 9. 5 % in the placebo Group. In reference to the add-on phase, median percent reduction in seizure frequency from baseline was 39. 9 % with Levetiracetam and 7. 2 % with placebo. Responder rate was 42. 1 % with Levetiracetam and 16. 7 % with placebo.

Side Effects

In a Pooled analysis of two control Pediatric clinical Studies in children 4 to 16 years of age with Partial Onset Seizures, Adverse Reactions most frequently reported with use of immediate-release Levetiracetam in combination with other AEDs, and with greater frequency than in patients on Placebo, were fatigue, aggression, nasal congestion, decrease appetite, and irritability. Table 5 lists Adverse Reactions that occur in at least 2 % of Pediatric Patients treated with immediaterelease Levetiracetam and were more common than in Pediatric Patients on Placebo. In these studies, either immediate-release Levetiracetam or Placebo was Add to concurrent AED therapy. Adverse reactions were usually mild to moderate in intensity. Table 5: Adverse Reactions in Pooled Placebo-control, Add-On Studies in Pediatric Patients aged 4 to 16 Years Experiencing Partial Onset Seizures in Controlled Pediatric clinical Studies in Patients 4-16 Years of age, 7 % of patients treated with immediate-release Levetiracetam Tablets and 9 % of Patients on Placebo discontinue as result of Adverse event. In addition, following Adverse Reactions were seen in other Controlled Studies of immediate-release Levetiracetam Tablets: balance disorder, disturbance in attention, eczema, hyperkinesia, memory impairment, myalgia, personality disorders, pruritus, and blur vision.

What Is Keppra XR?

Following Adverse Reactions are discussed in more details in other sections of labeling: psychiatric Reactions Suicidal Behavior and Ideation Somnolence and Fatigue Serious Dermatological Reactions Coordination Difficulties Withdrawal Seizures Hematologic Abnormalities Seizure Control During Pregnancy because clinical trials are conducted under widely varying conditions, Adverse reaction rates observed in clinical trials Of drug cannot be directly compare to rates in clinical trials Of another drug and may not reflect rates observe in practice. Prescribers should be aware that Adverse reaction Incidence figures in the following table, obtained when KEPPRA XR was Add to concurrent AED therapy, cannot be used to predict 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, cite frequencies cannot be directly compared with figures obtained from other clinical investigations involving different treatments, use, or investigators. Inspection of these frequencies, however, do provide prescribers with one basis to estimate the relative contribution of drug and non-drug factors to adverse reaction incidences in population study. In a Controlled clinical Study using KEPPRA XR in Patients with Partial Onset Seizures, most frequently reported Adverse Reactions in patients receiving KEPPRA XR in combination with other AEDs, for events with rates greater than Placebo, were irritability and Somnolence. Table 3 lists Adverse Reactions that occur in At Least 5 % Of epilepsy Patients treated with KEPPRA XR participating in the Placebo-Control Study and were numerically more common than in Patients treated with Placebo. In this Study, either KEPPRA XR or Placebo was Add to concurrent AED therapy. Adverse reactions were usually mild to moderate in intensity. Table 3: Incidence Of Adverse Reactions in Placebo-Control, Add-On Study by Body System in Controlled clinical Study using KEPPRA XR, 5. 2 % Of Patients receiving KEPPRA XR and 2. 5 % receiving Placebo discontinue as result of Adverse reaction. Adverse Reactions that result in discontinuation and that occur More Frequently in KEPPRA XR-treat Patients Than in Placebo-Treated Patients were asthenia, epilepsy, mouth ulceration, rash and respiratory failure. Each of these Adverse Reactions lead to discontinuation in KEPPRA XR-treat patients and no Placebo-Treated Patients. Table 4 lists Adverse Reactions seen in Controlled Studies Of Immediate-Release KEPPRA Tablets in adult Patients Experiencing Partial Onset Seizures. Although the pattern of Adverse Reactions in the KEPPRA XR Study seems somewhat different from that seen in Partial Onset Seizure Control Studies for Immediate-Release KEPPRA Tablets, this is possibly due to the much smaller number of Patients in this Study compared to Immediate-Release tablet Studies. Adverse Reactions for KEPPRA XR are expected to be similar to those seen with Immediate-Release KEPPRA Tablets. In Controlled clinical Studies Of Immediate-Release KEPPRA Tablets as adjunctive therapy to other AEDs in Adults with Partial Onset Seizures, most frequently reported adverse reactions, for events with rates greater than Placebo, were somnolence, asthenia, infection and dizziness.

DESCRIPTION

Treatment should be initiated with a dose of 1000 mg once daily. Daily dosage may be adjusted in increments of 1000 mg every 2 weeks to a maximum recommended daily dose of 3000 mg. Levetiracetam extend-Release Tablet dosing must be individualized according to patients ' renal function status. Recommend doses and adjustments for dose for adults are shown in Table 1. To use this dosing Table, estimate of patients creatinine clearance in mL / min is needed. CLcr in mL / min may be estimated from serum creatinine determination using the following formula: x weight CLcr =-x 1 0. 85 72 x serum creatinine then CLcr is adjusted for body surface area as follow: CLcr CLcr =-x 1. 73 BSA subject because Clinical trials are conducted under widely varying conditions, adverse reaction rates observed in Clinical trials of drug cannot be directly compared to rates in Clinical trials of another drug and may not reflect rates observed in practice. Prescribers should be aware that adverse reaction incidence figures in the following Table, obtained when Levetiracetam extend-Release Tablets were added to concurrent AED therapy, cannot be used to predict the frequency of adverse experiences in the course of usual medical practice where patient characteristics and other factors may differ from those prevailing during Clinical studies. Similarly, cite frequencies cannot be directly compared with figures obtained from other clinical investigations involving different treatments, use, or investigators. Inspection of these frequencies, however, do provide prescribers with one basis to estimate the relative contribution of drug and nondrug factors to adverse reaction incidences in population study. In a Well-Control Clinical Study using Levetiracetam extend-Release Tablets in patients with partial onset seizures, most frequently reported adverse reactions in patients receiving Levetiracetam extend-Release Tablets in combination with other AEDs, not seen at equivalent frequency among placebo-treated patients, were irritability and somnolence. Table 3 lists treatment-emergent adverse reactions that occur in at least 5 % of epilepsy patients treated with Levetiracetam extend-Release Tablets participating in the placebo-Control Study and were numerically more common than in patients treated with placebo. In this Study, either Levetiracetam extend-Release Tablets or placebo were added to concurrent AED therapy. Adverse reactions were usually mild to moderate in intensity. Discontinuation or Dose Reduction in Levetiracetam extend-Release Tablet Well-Control Clinical Study in Well-Control Clinical Study using Levetiracetam extend-Release Tablets, 5. 2 % Of patients receiving Levetiracetam extend-Release Tablets and 2. 5 % receiving placebo discontinue as result of adverse event. Adverse reactions that result in discontinuation and that occur more frequently in Levetiracetam extend-Release Tablet-treat patients than in placebo-treated patients were asthenia, epilepsy, mouth ulceration, rash and respiratory failure. Each of these adverse reactions leads to discontinuation in Levetiracetam extend-Release Tablet-treat patients and no placebo-treated patients. There is insufficient data for Levetiracetam extend-Release Tablets to support statement regarding distribution of adverse experience reports by gender, age and race. Table 4 lists adverse reactions seen in Well Controlled studies of immediate-Release levetiracetamtablets in adult patients experiencing partial onset seizures.

DOSAGE AND ADMINISTRATION

For adults and adolescent patients, recommended dosing for monotherapy and adjunctive therapy is the same; as outlined below. Adults and Adolescents 12 Years of Age and Older Weighing 50 kg or More initiate treatment with a dose of 1000 mg once daily. Once daily dosage may be adjusted in increments of 1000 mg every 2 weeks to the maximum recommended daily dose of 3000 mg / day. Levetiracetam extend-release Tablets are administered once daily. Levetiracetam extend-release Tablets should be swallowed whole. Tablets should not be chew, broken, or crush. Levetiracetam extend-release Tablets dosing must be individualized according to the patient's renal function status. Recommend dosage adjustments for adults are shown in Table 1. In order to calculate the dose recommended for patients with renal impairment, creatinine clearance adjust for body surface area must be calculate. To do this, estimate of the patient's creatinine clearance in ML / min must first be calculated using the following formula: then CL cr is adjusted for body surface area as follow: CL cr =-x 1. 73 avoid abrupt withdrawal from levetiracetam extend-release Tablets in order to reduce risk of increased seizure frequency and status epilepticus. Signs and symptoms of extend-release levetiracetam Tablets overdose are expected to be similar to those seen with immediate-release levetiracetam Tablets. The highest known dose of oral immediate-release levetiracetam received in the Clinical development program was 6000 mg / day. Other than drowsiness, there were no adverse reactions in few known cases of overdose in clinical trials. Cases of somnolence, agitation, aggression, depressed level of consciousness, respiratory depression and coma were observed with immediate-release levetiracetam overdoses in postmarketing Use. There is no specific antidote for overdose with Extended-release levetiracetam Tablets. If indicate, elimination of unabsorbed Drug should be attempted by emesis or gastric lavage; usual precautions should be observed to maintain airway. General supportive Care of patient is indicated, including monitoring of vital signs and observation of the patient's clinical status. Certify Poison Control Center should be contacted for up to date information on management of overdose with extend-release levetiracetam Tablets. Standard hemodialysis procedures result in significant clearance of levetiracetam and should be considered in cases of overdose. Although hemodialysis has not been performed in few known cases of overdose, it may be indicated by patient's clinical state or in patients with significant renal impairment. Levetiracetam extend-release Tablets USP, 500 mg are white to off white, oblong-shaped, biconvex, film coat Tablets, imprint 'L008' on one side and plain on other side.

HOW SUPPLIED

Antiepileptic drug treatment is recommended for cats with frequent or prolonged seizures to minimize secondary brain damage. Many cats are resistant to frequent administration of medications PO throughout the day, leading to poor treatment adherence by clients and resultant wide fluctuations in serum concentrations. 1-3 levetiracetam is AED approved for use in humans. Its novel mechanism of action coupled with minimal reported adverse effects make it an appealing drug for seizure control in cats. 4 5 Pharmacokinetics of intermediaterelease levetiracetam administered PO in cats support 20-25 mg / kg dosage, but short elimination halflife of 2. 95 0. 95 hours necessitates q8h dosing regimen, decreasing owner compliance. 4 6 7 extendedrelease formulation of levetiracetam is specially formulated to result in lower maximal drug concentration, longer time to maximal concentration and less fluctuation in serum concentrations in humans when compared to IRL. 1 Its use in cats has not been evaluated previously. One of the reasons it has not been evaluated is likely that the smallest tablet size is 500 mg. Cutting, crushing, or breaking tablets compromises extendedrelease properties. PO dosage administered to cat would result in dosage of approximately 100 mg / kg / d in average 5kg cat. Yet, clinically, based on therapeutic drug monitoring data, levetiracetam may be safe enough for this dose to be well tolerate. The purposes of our study were to describe disposition of single 500 mg dose of XRL in healthy cats and document clinical adverse effects after administration. Our hypotheses were that Serum levetiracetam concentrations would remain 5 g / ML for 24 hours postpill administration, and the drug would be well tolerated by healthy cats.

PRECAUTIONS

In the KEPPRA XR double-blind, control trial in patients experiencing partial onset seizures, 8 % of KEPPRA XR-treat patients experience somnolence compared to 3 % of placebo-treated patients. No patient discontinued treatment or had dose reduction as result of these adverse reactions. The number of patients exposed to KEPPRA XR was considerably smaller than the number of patients exposed to immediate-Release KEPPRA Tablets in controlled trials. Therefore, certain adverse reactions observed in immediate-Release KEPPRA control trials will likely occur in patients receiving KEPPRA XR. In controlled trials of adult patients with epilepsy experiencing partial onset seizures, 15 % of KEPPRA-treated patients report somnolence, compared to 8 % of placebo-treated patients. There was no clear dose response up to 3000 mg / day. In study where there was no titration, about 45 % of patients receiving 4000 mg / day report somnolence. Somnolence was considered serious in 0. 3 % of KEPPRA-treated patients, compared to 0 % in the placebo group. About 3 % of KEPPRA-treated patients discontinue treatment due to somnolence, compared to 0. 7 % of placebo-treated patients. In 1. 4 % of KEPPRA-treated patients and in 0. 9 % of placebo-treated patients ' dose was reduce, while 0. 3 % of treated patients were hospitalized due to somnolence.

CLINICAL PHARMACOLOGY

Effectiveness Of KEPPRA XR as adjunctive therapy in Partial Onset Seizures in adults was established in one multicenter, randomize, double-blind, Placebo-control clinical Study in patients who had refractory Partial Onset Seizures with or without secondary generalization. This was supported by demonstration of efficacy of immediate-Release KEPPRA Tablets in Partial Seizures in three multicenter, randomize, double-blind, Placebo-control clinical studies in adults, as well as demonstration of comparable bioavailability between XR and immediate-Release formulations in adults. Effectiveness of KEPPRA XR as adjunctive therapy in Partial Onset Seizures in pediatric patients, 12 years of age and older, was based upon a single pharmacokinetic study showing comparable pharmacokinetics of KEPPRA XR in adults and adolescents. All studies are described below.
