Lamotrigine augmentation in delirium tremens.

Introduction: Delirium tremens (DT) is most severe neurological complication of alcohol withdrawal with high mortality rate. DT is related to an altered balance of excitatory and inhibitory amino-acid neurotransmitters, which is basically due to upregulation of glutaminergic neurotransmission induced by chronic ethanol exposure. Lamotrigine (LTG) is believed to act by reducing excitatory glutamate release due to inhibition of Na (+) channels.
