promethazine
Treatment for Cluster Headache
Promethazine is a first-generation H1 receptor antagonist with antihistaminic and anticholinergic properties that can help manage cluster headache symptoms by reducing nausea, inducing mild sedation, and potentially modulating neurogenic inflammation. Its mechanism of action involves blocking histamine receptors and potentially inhibiting serotonin pathways, which may contribute to its effectiveness in alleviating headache-related symptoms.
