Recently synthesized triptans, sumatriptan derivatives, display aborting migraine activity at doses and with plasmatic maximum peak dramatically lower (20-40 times) than sumatriptan, the 5-HT like agonist, which is the original molecule. That triptans easily cross blood-brain barrier strongly supports the central theory of migraine. We recently discovered the anti-migraine prophylactic action of centrally acting anti-cholinesterase agents, that seems a further support to the central theory of migraine. Indeed, acetylcholine is an important analgesia neurotransmitter and is intertwined with 5-HT central pathways.
