New vistas on 5-HT receptors and migraine

1. A number of serotonergic agents have been shown to be effective in the treatment of migraine. At the present time, migraine drug interactions have been analyzed most extensively at 5-hydroxytryptamine1D (5-HT1D ), 5-HT2 and 5-HT3 receptor subtypes. 2. This review will summarize the current status of 5-HT receptor subtypes as they relate to anti-migraine agents. 3. The available data suggest that drug interactions with specific 5-HT receptor subtypes may be the basis for their efficacy in both the acute and prophylactic treatment of migraine.
