一般的な説明
Naratriptan, the third triptan approved in 1998, is one of themost lipophilic triptans marketed to date. It has a much improvedbioavailability (63% in men and 74% in women), agreater affinity for 5-HT1B/1D receptors (3–6 times), and alower recurrence rate than sumatriptan because of its muchlonger elimination half-life. Naratritan also has a favorableCNS side effect profile when compared with sumatriptanor zolmitriptan because of its metabolic stability,thereby lacking a N-demethylated active metabolite and asignificant renal excretion ( 70% of naratriptan is excretedunchanged and the rest of the administered dose is degradedvia several CYP isozymes).
