Summary

The purpose of this study is:

• To compare the single-dose pharmacokinetics (PK) of intranasal administration of 20 mg OPTINOSE SUMATRIPTAN with 20 mg IMITREX® (sumatriptan) Nasal Spray, 100 mg IMITREX® (sumatriptan) Oral Tablet, and 6 mg IMITREX® (sumatriptan) Subcutaneous Injection, in healthy subjects.
