In single-dose study, 2.5, 5, and 10 mg oral doses of frovatriptan succinate tablet were administrated. A 2.5 mg frovatriptan succinate tablet was administrated 12 times in 7 days in the multiple-dose study. Blood samples were collected at scheduled time points.Results: The results in single-dose study indicated that the blood levels were proportional to the administered dose, with the mean Cmax and AUClast ranging from approximately 6.27 ng/mL- 17.35 ng/mL and 92.52 h⋅ng/mL - 287.40 h⋅ng/mL over the dose range. In the multiple-dose study, moderate drug accumulation was noted, which was attributable to forvatriptan's long t1/2 of about 26.47 to 30.63 h. Gender differences were noticed in both single- and multiple-dose study; exposure PK parameters were consistently higher in female than in male.Conclusion: These pharmacokinetic evaluations in healthy Chinese subjects found that frovatriptan succinate tablet has an acceptable pharmacokinetic profile in Chinese subjects.Keywords: frovatriptan succinate, pharmacokinetics, single-dose, multiple-dose
