Clinical experience of marketed Levetiracetam in an epilepsy clinic-a one year follow up study.
Levetiracetam is a new anti-convulsant with impressive pivotal trial credentials. We examined its effectiveness in refractory clinic patients with epilepsy with a year's follow up. Six months after initiation 32% of the patients were seizure free, and 26% at one year. By the end of the 12 months follow up 77% of patients were still taking the drug, having gained benefit from it: 23% had dropped out due to intolerable side effects, seizure increase or lack of efficacy. There is evidence that the drug is broad spectrum and as effective in primary generalised epilepsy as in partial onset epilepsy. Our audit of its use and effectiveness has led us to position it as our first choice add-on drug if the initial monotherapy drug fails.
