Outcome Measures

Primary Outcomes (1)

• Pharmacokinetics

  The primary objective was to compare the pharmacokinetics (PK) of NP101 (sumatriptan iontophoretic transdermal patch) with the currently approved oral, subcutaneous injection and nasal spray formulations of Imitrex® in healthy volunteers and to assess the bioavailability relative to the 6 mg subcutaneous injection.

  Blood samples to be drawn at pre-dose (within 15 minutes prior to dosing) and at 0.25, 0.50, 1, 1.5, 2, 3, 4, 6, 8, 10, 12 and 16 hrs post dose.
