Detailed Description:

A single center, randomized, single-dose, open-label, partial-block, four-period, four-way crossover study in 54 healthy adult subjects to evaluate the pharmacokinetics and bioequivalence of sumatriptan delivered by the Intraject system compared to IMITREX STATdose at three injection sites (abdomen, thigh, and arm.)
