产品描述:
Sumatriptan is an agonist of the serotonin (5-HT) receptor subtypes 5-HT1B and 5-HT1D (IC50s = 9.3 and 7.3 nM, respectively).{23129} It also binds to the 5-HT1F receptor (IC50 = 17.8 nM). It induces vasoconstriction in isolated human middle meningeal arteries (EC50 = 89.9 nM), an effect that can be reduced by the 5-HT1B/1D receptor antagonists GR125,743 and GR127,935. Sumatriptan reduces acute, but not chronic, mechanical hyperalgesia in a mouse model of pain induced by nitroglycerin, which is a known migraine trigger in humans.{48340} Formulations containing sumatriptan have been used in the treatment of migraine headache.
