UCB announced findings from new studies of the oncedaily antiepileptic drug (AED) Keppra XR(TM) (levetiracetam) extendedrelease tablets comparing tolerability versus levetiracetam immediate release (IR) and reporting on additional dosing schedules. The evidence were among five studies that were presented at the 62nd annual meeting of the American Epilepsy Society (AES) in Seattle.

Keppra XR was approved by the U.S. Food and Drug Administration in September 2008 for use as adjunctive treatment for inhabitants with partialonset seizures who are 16 years of age and older.

“In that new metaanalysis, patients taking Keppra XR experienced fewer nervous conformity side effects than those taking the lookalike dose of twice daily levetiracetam,” said James Zackheim, Medical Director, CNS, UCB. “Keppra XR is the only oncedaily, extendedrelease formulation of levetiracetam, and there is no generic alternative available.”

Safety Profile of Levetiracetam Extended Release Compared to Immediate Release An Indirect Comparison Using a MetaAnalytic Approach

Researchers conducted a metaanalysis of Phase III poop sheet to determine whether Keppra XR is associated with any tolerability advantages versus the double daily dose of levetiracetam IR. According to the metaanalysis, patients taking Keppra XR oncedaily had lower weights of some adverse events versus levetiracetam IR twicedaily.

In terms of overall tolerability, 52.8% of Keppra XR patients reported any adverse event, compared with 79% of patients taking levetiracetam IR.

While adverse events associated with levetiracetam IR were more observed with Keppra XR, patients treated with Keppra XR oncedaily experienced statistically significantly lower weights of adverse events enmeshed to nervous totality disorders (i.e., headache, somnolence and dizziness) versus levetiracetam IR twicedaily.

Keppra XRtreated patients reported numerically lower quotas of psychiatric disorders (i.e., nervousness, anxiety and depression) and nutrition/metabolism disorders.

No other differences in weights of adverse events were statistically significant.

original Dose Bioequivalence bounded by Levetiracetam 2 x 750 mg XR Tablets and 3 x 500 mg XR Tablets and Food Effect on 2 x 750 mg XR Tablets in Healthy Subjects

that study demonstrated that an investigational 750 mg tablet strength of Keppra XR is bioequivalent to the approved 500 mg tablet when these are each combined to achieve a 1,500 mg dose. Results Showboat that a rare dose of 2 x 750 mg Keppra XR tablets was bioequivalent to a 3 x 500 mg undivided dose of Keppra XR in healthy adults, and that food intake did not significantly modify Keppra XR 2 x 750 mg disposition.

The median instance to peak plasma concentration was approximately 4 to 5 hours for each dose.

Each dose resulted in a similar halflife (the epoch imperious for half the quantity of a drug in the body to be metabolized or eliminated), apparent total clearance (the rate at which a drug in the body is metabolized or eliminated), and apparent total distribution (the amount of fluid that would be cryed for to dissolve the total amount of drug needed to achieve the carbon counterpart concentration as that construct in the blood).

When the 2 x 750 mg Keppra XR dose was taken with food, the tour to peak concentration was increased by 2 hours relative to fasted intake, while Cmax (the peak concentration of a drug in the body) remained within bioequivalence limits.

For all three Keppra XR dosing schedules (3 x 500 mg, 2 x 750 fasted and 2 x 750 fed), tolerability was privileged and the amounts of treatmentemergent adverse events were similar opposite all associations; in adjoining, adverse events were virtually all mild, and all resolved by the end of the study.

serious Safety leak

Keppra XR(TM) extendedrelease tablets are indicated as adjunctive therapy in the treatment of partial onset seizures in patients 16 years of age and older with epilepsy.

Keppra XR(TM) causes somnolence, dizziness, and behavioral abnormalities. The highest common adverse reactions observed with Keppra XR(TM) in combination with other AEDs were somnolence and irritability.

The adverse reactions that may be seen in patients receiving Keppra XR(TM) are expected to be similar to those seen in patients receiving immediaterelease Keppra(R) tablets.

Keppra(R) immediaterelease tablets cause somnolence and fatigue, coordination difficulties, and behavioral abnormalities (e.g., psychotic symptoms, suicidal ideation, and other abnormalities), as well as hematological abnormalities. In adults experiencing partial onset seizures, the utmost common adverse reactions observed with Keppra(R) in combination with other AEDs were somnolence, asthenia, infection and dizziness.

Keppra XR(TM) should be gradually withdrawn to minimize the probable of increased seizure iteration.

Dosing must be individualized according to the patients renal affair status. In patients with endstage renal disease on dialysis, it is recommended that immediaterelease Keppra(R) be used instead of Keppra XR(TM).

About Epilepsy

Epilepsy is a chronic neurological disorder affecting approximately three million public in the U.S. making it more common than multiple sclerosis and Parkinsons disease combined. It is caused by abnormal, excessive electrical discharges of the nerve cells, or neurons, in the brain. Epilepsy is characterized by a tendency to have recurrent seizures and defined by two or more unprovoked seizures. There are frequent contrary seizure types and epileptic syndromes. Forty percent of patients taking only one AED linger to struggle seizures, and approximately 30% of patients taking adjunctive therapy maintain to actuality seizures. that highlights the ongoing hurting for for the development of new AEDs.
