Abstract
▴ Eletriptan is a new serotonin 5-HT1B/1D receptor agonist developed for the treatment of acute migraine attacks.
▴ The increased lipophilicity of eletriptan provides rapid absorption, and improved oral bioavailability over that of sumatriptan.
▴ In animal studies, eletriptan effectively decreased carotid anastomotic blood flow, but exhibited a lower potential than sumatriptan to constrict coronary and femoral blood flow in a canine assay of potential adverse cardiovascular effects.
▴ Eletriptan was effective in reducing migraine pain from severe or moderate to mild or none within 2 hours of administration of a single oral 40 or 80mg dose in a large, multicentre, double-blind placebo-controlled trial (n = 1151).
▴ In a double-blind, placebo-controlled comparative study, eletriptan (80mg, single oral dose) was significantly more effective than sumatriptan (100mg, single oral dose) in reducing headache pain at both 1 and 2 hours after administration (n = 692).
▴ Eletriptan is generally well tolerated. The most commonly reported adverse events were asthenia, somnolence, dizziness and nausea; these were typically mild and transient in nature.
