The functional activity of eletriptan ((R)-3-(1-methyl-2-pyrrolidinylmethyl)-5-[2-(phenylsulphonyl )ethyl]- 1 H-indole) at the contractile serotonin (5-hydroxytryptamine; 5-HT) '1B-like' receptor in dog isolated saphenous vein and basilar artery was investigated. Eletriptan, like 5-HT and sumatriptan potently contracted saphenous vein (pEC50: 6.3, 6.9 and

European journal of pharmacology, 368(2-3), 259-268 (1999-04-08)
The affinity of eletriptan ((R)-3-(1-methyl-2-pyrrolidinylmethyl)-5-[2-(phenylsulphonyl )ethyl]-1H-indole) for a range of 5-HT receptors was compared to values obtained for other 5-HT1B/1D receptor agonists known to be effective in the treatment of migraine. Eletriptan, like sumatriptan, zolmitriptan, naratriptan and rizatriptan had highest

It has been suggested that opening of cephalic arteriovenous anastomoses may be involved in the headache phase of migraine. Indeed, a number of acutely acting anti-migraine drugs, including the ergot alkaloids and sumatriptan, constrict porcine carotid arteriovenous anastomoses. In this
