Reduction of AEDs in postsurgical patients who attain remission.

PURPOSE: Little evidence guides practice regarding the reduction of antiepileptic drugs (AEDs) in individuals who achieve significant periods of remission after resective surgery. METHODS: In a prospective study of 396 individuals who underwent resective surgery for intractable seizures, the impact of reducing AEDs on relapse and predictors of relapse were examined. RESULTS: Of 301 study subjects who attained a 1-year seizure remission after surgery, 129 reduced from two to one or from one to no AEDs after achieving remission, and 162 did not reduce drugs. Ten patients who stopped all AEDs before attaining remission were excluded from analysis. In all, 114 (39%) patients relapsed: 73 (45%) of 162 in the nonreduction group and 41 (32%) of 129 in the reduction group (p = 0.02). Patients who reduced drugs were more likely to have remitted immediately after hospital discharge (p<0.0001). After adjustment for this factor, little or no apparent impact of drug reduction on the rate of relapse was noted [rate ratio (RR), 1.1; 95% CI, 0.72-1.71; p=0.64 for reducing from two to one AED, and RR, 0.85; 95% CI, 0.50-1.45; p=0.56 for reducing from one to no AEDs]. Within the 129 patients who reduced AEDs, only delayed remission after hospital discharge was significantly associated with an increased rate of relapse (RR, 2.26; 95% CI, 1.15- 4.48; p=0.02). Continued auras had a marginally significant association with relapse (RR, 2.06; p=0.07) CONCLUSIONS: Although many relapses in this cohort of postsurgical patients who achieved remission occurred in the context of reducing or completely eliminating AEDs, the risk was no higher than in those who continued AEDs. Randomized studies are needed to test the impact of drug reduction in seizure-free postsurgical patients.

Efficacy and tolerability of the new antiepileptic drugs, I: Treatment of new-onset epilepsy: report of the TTA and QSS Subcommittees of the American Academy of Neurology and the American Epilepsy Society.

PURPOSE: To assess the evidence demonstrating efficacy, tolerability, and safety of seven new antiepileptic drugs [AEDs; gabapentin (GBP), lamotrigine (LTG), topiramate (TPM), tiagabine (TGB), oxcarbazepine (OXC), levetiracetam (LEV), and zonisamide (ZNS), reviewed in the order in which these agents received approval by the U.S. Food and Drug Administration] in the treatment of children and adults with newly diagnosed partial and generalized epilepsies. METHODS: A 23-member committee, including general neurologists, pediatric neurologists, epileptologists, and doctors in pharmacy, evaluated the available evidence based on a structured literature review including MEDLINE, Current Contents, and Cochrane Library for relevant articles from 1987 until September 2002, with selected manual searches up to 2003. RESULTS: Evidence exists, either from comparative or dose-controlled trials, that GBP, LTG, TPM, and OXC have efficacy as monotherapy in newly diagnosed adolescents and adults with either partial or mixed seizure disorders. Evidence also shows that LTG is effective for newly diagnosed absence seizures in children. Evidence for effectiveness of the new AEDs in newly diagnosed patients with other generalized epilepsy syndromes is lacking. CONCLUSIONS: The results of this evidence-based assessment provide guidelines for the prescription of AEDs for patients with newly diagnosed epilepsy and identify those seizure types and syndromes for which more evidence is necessary.

Efficacy and tolerability of the new antiepileptic drugs, II: Treatment of refractory epilepsy: report of the TTA and QSS Subcommittees of the American Academy of Neurology and the American Epilepsy Society.

PURPOSE: To assess the evidence demonstrating efficacy, tolerability, and safety of seven new antiepileptic drugs (AEDs) [gabapentin (GBP), lamotrigine (LTG), topiramate (TPM), tiagabine (TGB), oxcarbazepine (OXC), levetiracetam (LEV), and zonisamide (ZNS)] in the treatment of children and adults with refractory partial and generalized epilepsies. METHODS: A 23-member committee, including general neurologists, pediatric neurologists, epileptologists, and doctors in pharmacy, evaluated the available evidence based on a structured literature review including MEDLINE, Current Contents, and Cochrane Library for relevant articles from 1987 to March 2003. RESULTS: All of the new AEDs were found to be appropriate for adjunctive treatment of refractory partial seizures in adults. GBP can be effective for the treatment of mixed seizure disorders, and GBP, LTG, OXC, and TPM for the treatment of refractory partial seizures in children. Limited evidence suggests that LTG and TPM also are effective for adjunctive treatment of idiopathic generalized epilepsy in adults and children, as well as treatment of the Lennox-Gastaut syndrome. CONCLUSIONS: The choice of AED depends on seizure and/or syndrome type, patient age, concomitant medications, and AED tolerability, safety, and efficacy. The results of this evidence-based assessment provide guidelines for the prescription of AEDs for patients with refractory epilepsy and identify those seizure types and syndromes for which more evidence is necessary.
