an open-label, randomized, 3-period crossover study to evaluate sumatriptan pharmacokinetics for a trexima™ (sumatriptan succinate / naproxen sodium) tablet followed by imitrex® (sumatriptan succinate)

Conditions: Migraine Disorders

Summary: this study will evaluate the exposure of sumatriptan after administration of trexima (sumatriptan 85mg/naproxen sodium 500mg) followed by a subcutaneous imitrex injection (4mg or 6mg) 2 hours later compared to administration of a imitrex 100mg tablet followed by a imitrex 100mg tablet 2 hours later.

an open-label, randomized, 3-period crossover study to evaluate sumatriptan pharmacokinetics for a trexima™ (sumatriptan succinate / naproxen sodium) tablet followed by imitrex® (sumatriptan succinate) injection 4mg administered using the imitrex statdose system® and a trexima tablet followed by imitrex® (sumatriptan succinate) injection 6mg administered using the imitrex statdose system® compared with an imitrex tablet 100mg followed by an imitrex tablet 100mg.
