nasal decongestants
Treatment for Cluster Headache
Nasal decongestants, such as pseudoephedrine, act by stimulating alpha-adrenergic receptors in the nasal mucosa, causing vasoconstriction and reducing tissue inflammation. In the context of Cluster Headache, these agents may provide rapid symptomatic relief by reducing mucosal congestion and potentially alleviating the intense trigeminal nerve-mediated pain associated with the condition.
