venlafaxine
Treatment for Cluster Headache
Venlafaxine is a serotonin-norepinephrine reuptake inhibitor (SNRI) that modulates neurotransmitter activity in the central nervous system, potentially reducing neurogenic inflammation and pain signaling associated with cluster headaches. By increasing synaptic concentrations of serotonin and norepinephrine, it may help stabilize neural pathways and provide prophylactic management of cluster headache episodes through its neuromodulatory effects.
