ANTIEPILEPTIC
ACTION AND CLINICAL PHARMACOLOGY
Lamotrigine is a drug of the phenyltriazine class chemically unrelated
to existing antiepileptic drugs
(AEDs).
Lamotrigine is thought to act at voltage-sensitive sodium channels to
stabilize neuronal membranes
and inhibit the release of excitatory amino acid neurotransmitters
(e.g. glutamate, aspartate) that are
thought to play a role in the generation and spread of epileptic
seizures.
CLINICAL TRIALS
In adult placebo-controlled clinical studies, lamotrigine has been
shown to be effective in reducing
seizure frequency and the number of days with seizures when added to
existing antiepileptic drug
therapy in adult patients with partial seizures,
with or without generalized tonic-clonic seizures, that
are not satisfactorily controlled.
The effectiveness of lamotrigine adjunctive therapy has also been
shown in pediatric and adult
patients with Lennox-Gastaut syndrome. A significant reduction in
major motor seizures, drop
attacks, and tonic-clonic seizures were seen following lamotrigine
treatment compared with placebo
treated patients. Improvements in cognitive skills (speech, nonverbal
communication, alertness,
attention, intellectual capacity), behaviour, and fine coordination
have been seen with lamotrigine
treatment in these patients.
Studies have also been conducted using lamotrigine monotherapy in
adult patients (n = 443) newly
diagnosed with epilepsy (partial seizures, with or without secondary
generalization or primary
generalized tonic clonic). Resu
