  3. clinically significant intra-ventricular conduction abnormalities (left bundle branch block or Wolf-Parkinson-White syndrome), or
  4. clinically significant arrhythmias (e.g., current atrial fibrillation)
• Able to understand the operation of the electronic diary and is able to apply the demo study drug patch.

Exclusion Criteria:

• Subjects who have known allergy or sensitivity to zolmitriptan or its derivatives or formulations
• Subjects who have known allergy or sensitivity to adhesives
• Planned participation in activities which cause inflammation, irritation, sunburn, lesions, or tattoos at the intended application site from two weeks prior to screening through the last day of study participation
• Use of opiate analgesics or barbiturates more frequently than one day/week
• Women who are pregnant, breast-feeding or plan a pregnancy during this study
• Clinically significant liver disease
• Clinically significant kidney disease
• History of coronary artery disease (CAD), coronary vasospasm (including Prinzmetal's angina), aortic aneurysm, peripheral vascular disease or other ischemic diseases (e.g., ischemic bowel syndrome or Raynaud's syndrome)

  • Diabetes mellitus
• History of cerebral vascular accident, transient ischemic attacks, or seizures
• Hospitalization within the 30 days prior to the Run-in Period
• Any other household member currently participating in a ZP-Zolmitriptan study or relatives of site staff
• Any reason to believe that compliance with the study requirements and completion of evaluations required for this study will not be possible
• History or current abuse or dependence on alcohol or drugs that would interfere with adherence to study requirements
• Any clinically relevant abnormal findings in the physical exam, vital signs or laboratory tests that, in the opinion of the Investigator, may put the subject at risk

To be eligible for Treatment, subjects must continue to meet all eligibility criteria and the following criteria observed during the Run-in Period:

1. An average of at least two qualifying migraines per 28-day period
2. No more than 10 headache days in the last 28 days prior to randomization
3. Demonstrated ability to properly use the eDiary and apply the demo study drug patch
4. Confirmation of continuing good general health, or stable non-serious disease that in the opinion of the Investigator will not place the subject at risk.
