Mechanism of action
Nortriptyline enhances monoaminergic neurotransmission by blocking reuptake of norepinephrine and serotonin, which modulates pain perception and mood. Topiramate acts through multiple mechanisms including voltage-gated sodium channel blockade, potentiation of GABA, and carbonic anhydrase inhibition, contributing to analgesic and mood-stabilizing effects. The combination leverages complementary mechanisms for enhanced efficacy in conditions like chronic pain and depression.
