Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To determine zolmitriptan and/or its active metabolite 183C91 occupancy at 5-HT1B receptors in the living human brain [ Time Frame: The first PET measurement will serve as a baseline assessment. The second, third and fourth PET measurements will be performed after oral administration of ZOMIG® Rapimelt (10 mg, 5 mg and 2.5 mg, respectively). ]

Secondary Outcome Measures:
  • To describe the relation between Zomig® Rapimelt dose and 5-HT1B receptor occupancy [ Time Frame: The second, third and fourth PET measurements will be performed after oral administration of ZOMIG® Rapimelt (10 mg, 5 mg and 2.5 mg, respectively). Imaging data analysis will be performed after each PET measurement ]
  • To describe the relation between plasma concentrations of zolmitriptan and 183C91 and 5-HT1B receptor occupancy [ Time Frame: For each of 3 visits venous blood for zolmitriptan and 183C91 PK analyses taken before drug administration and at 3 time points during PET examination: start, middle and end, ie, at 0, +30 and + 63 minutes relative to injection of the radioli ]
