• Subject, in the investigator's opinion, is likely to have unrecognized cardiovascular or cerebrovascular disease (See Appendix 1, section 11.1).
• Subject has uncontrolled hypertension (See Appendix 2, section 11.2) or is taking any angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker.
• Subject has a history of congenital heart disease, cardiac arrhythmias requiring medication, or a history of a clinically significant electrocardiogram abnormality that, in the investigator's opinion, contraindicates participation in this study.
• Subject has evidence or history of any ischemic vascular diseases including: ischemic heart disease, ischemic abdominal syndromes, peripheral vascular disease or Raynaud's Syndrome, or signs/symptoms consistent with any of the above.
• Subject has evidence or history of central nervous system pathology including stroke and/or transient ischemic attacks (TIAs), epilepsy or structural brain lesions which lower the convulsive threshold; or has been treated with an antiepileptic drug for seizure control within 5 years prior to screening.
• Subject has a history of impaired hepatic or renal function that, in the investigator's opinion, contraindicates participation in this study.
• Subject has hypersensitivity, allergy, intolerance, or contraindication to the use of any triptan, NSAID or aspirin (including all sumatriptan and naproxen preparations) or has nasal polyps and asthma.
