Drug of Choice for Epilepsy Patient’s Medication Upon Admission ILAE Treatment Guidelines, 2006 Effectiveness-outcome evidence Based on RCT efficacy and effectiveness evidence, CBZ, LTG, OXC, PB, PHT, TPM, and VPA are possibly efficacious/effective as initial monotherapy for adults with GTC seizures and may be considered for initial therapy in selected situations (level C) (Glauser, et al. 2006) • Phenytoin (Dilantin) 100mg/cap TID Glauser, T, ElinorBM, BlaiseBs,et. al.

Maintenance Medications Home Medications Current Perspectives in Epilepsy Treatment: Focus on Monotherapy, 2006 Initial treatment of epilepsy should begin with AED monotherapy If initial trial fails, try monotherapy with a second AED Combination therapy should be considered only if the patient fails at least 2 monotherapytrials • Phenytoin 100mg/cap TID • Levetiracetam 500mg/tab BID • Citicoline 1gm/tab BID • ASA 80 gm/tab OD Pellock, John, and Michael Privitera.

RCT efficacy and effectiveness: CBZ, LTG, OXC, PB, PHT, TPM, and VPA are possibly efficacious/effective as initial monotherapy for adults with GTC seizures and may be considered for initial therapy in selected situations (level C) (Glauser, et al. 2006) • Phenytoin 100mg/cap TID • Levetiracetam 500mg/tab BID • Citicoline 1gm/tab BID • ASA 80 gm/tab OD Glauser, T, ElinorBM, BlaiseBs,et. al.

Post-stroke Maintenance Medications • Maintenance since Jan 2010, post stroke • ASA 80mg/tab OD • Dipyrimadole (Persantine) 200mg/tab BID • International Stroke Trial (IST, Lancet 1997;349:1569-1581) • Aspirin treated patients had slightly fewer deaths at 14 days, significantly fewer recurrent ischemic strokes at 14 days and no excess of hemorrhagic strokes • Dipyridamolefor Preventing Stroke and Other Vascular Events in Patients With Vascular Disease: An Update • Compared with control, dipyridamole had no clear effect on vascular death (RR 0.99, 95% CI, 0.87 to 1.12). • Compared with control, dipyridamoleappeared to reduce the risk of vascular events (RR 0.88, 95% CI, 0.81 to 0.95). • Routine use of dipyridamole alone as first line antiplatelet treatment is not supported. The combination of dipyridamole plus aspirin is associated with a lower risk of further vascular events than aspirin alone.
Discontinuation of Anticonvulsants • Specchio and colleagues • After 2 years on a single anticonvulsant during which no seizures had occurred, the rate of relapse was 40% 2 and a half years later and 50% at 5 years after discontinuation • For patients remaining on medication, seizure recurrence rate is 20%
Discontinuation of Anticonvulsants • When patient has been free of seizures for a prolonged period (?) • A safe plan, applicable to most forms of epilepsy, is to obtain an EEG whenever withdrawal of medication is contemplated. • If the tracing is abnormal by way of showing paroxysmal activity, it is generally better to continue treatment.
