orphenadrine
Treatment for Cluster Headache
Orphenadrine is a centrally-acting anticholinergic and antihistamine medication with muscle relaxant properties that may help modulate pain perception and reduce muscle tension in cluster headaches. By antagonizing muscarinic acetylcholine receptors and potentially influencing dopaminergic pathways, it can provide mild analgesic and muscle relaxant effects that may help mitigate the intense pain associated with cluster headache episodes.
