tricyclic antidepressants
Treatment for Cluster Headache
Tricyclic antidepressants, such as amitriptyline, modulate pain perception by inhibiting serotonin and norepinephrine reuptake in the central nervous system, which can reduce the frequency and intensity of cluster headaches. Their mechanism involves central pain modulation and potential sympathetic nervous system effects, with secondary benefits of improving sleep patterns and reducing neurogenic inflammation.
