BACKGROUND: Health care providers frequently cite concerns about cardiovascular safety of the triptans as a barrier to their use. In 2002, the American Headache Society convened the Triptan Cardiovascular Safety Expert Panel to evaluate the evidence on triptan-associated cardiovascular risk and to formulate consensus recommendations for making informed decisions for their use in patients with migraine. OBJECTIVE: To summarize the evidence reviewed by the Triptan Cardiovascular Safety Expert Panel and their recommendations for the use of triptans in clinical practice. PARTICIPANTS: The Triptan Cardiovascular Safety Expert Panel was composed of a multidisciplinary group of experts in neurology, primary care, cardiology, pharmacology, women's health, and epidemiology. EVIDENCE AND CONSENSUS PROCESS: An exhaustive search of the relevant published literature was reviewed by each panel member in preparation for an open roundtable meeting. Pertinent issues (eg, cardiovascular pharmacology of triptans, epidemiology of cardiovascular disease, cardiovascular risk assessment, migraine) were presented as a prelude to group discussion and formulation of consensus conclusions and recommendations. Follow-up meetings were held by telephone. CONCLUSIONS: (1) Most of the data on triptans are derived from patients without known coronary artery disease. (2) Chest symptoms occurring during use of triptans are generally nonserious and are not explained by ischemia. (3) The incidence of serious cardiovascular events with triptans in both clinical trials and clinical practice appears to be extremely low. (4) The cardiovascular risk-benefit profile of triptans favors their use in the absence of contraindications.

BACKGROUND: Triptans are widely used to treat migraine but have been associated with stroke, myocardial infarction (MI), and ischemic heart disease (IHD) in case reports. OBJECTIVE: To estimate the incidence of stroke, cardiovascular events, and death in a migraine cohort, stratified by triptan prescription, and investigate whether the risk of these events was increased in those treated with triptans. METHODS: Migraine patients and matched nonmigraine control subjects were identified from the General Practice Research Database. Computerized records were searched for triptan prescriptions, stroke, TIA, MI, IHD, death, arrhythmia, and confounding variables. Incidence rates were calculated and migraine groups compared with controls using a Cox model, adjusting for confounders. RESULTS: Of 63,575 migraine patients, 13,664 were prescribed a triptan. There was no association between triptan prescription and stroke (hazard ratio [HR] 1.13; 95% CI 0.78, 1.65), MI (HR 0.93; 95% CI 0.60, 1.43), or other outcomes studied. The larger group of migraine patients not prescribed a triptan had an increased risk of stroke (HR 1.51; 95% CI 1.26, 1.82) and IHD (HR 1.35; 95% CI 1.18, 1.54) and a decreased risk of all-cause mortality (HR 0.72; 95% CI 0.65, 0.80). CONCLUSIONS: IN GENERAL PRACTICE, TRIPTAN TREATMENT IN MIGRAINE DOES NOT INCREASE THE RISK OF STROKE, MI, CARDIOVASCULAR DEATH, IHD, OR MORTALITY. TRIPTANS ARE PRESCRIBED TO THOSE LESS AT RISK OF THESE EVENTS.

OBJECTIVE: To evaluate the efficacy and tolerability of zolmitriptan 5 mg and 10 mg nasal spray (ZNS) vs placebo in the acute treatment of cluster headache. Design/ METHODS: We conducted a multicenter, double-blind, randomized, three-period crossover study using ZNS 5 mg, ZNS 10 mg, and placebo. Headache intensity was rated by a 5-point scale: none, mild, moderate, severe, or very severe. The primary efficacy measure was headache response (pain reduced from moderate, severe, or very severe at baseline, to mild or none) at 30 minutes. Logistic regression was used to account for treatment period effect as well as for cluster headache subtype effect. RESULTS: A total of 52 adult patients treated 151 attacks. For the primary endpoint, both doses reached significance at 30 minutes (placebo = 30%, ZNS 5 mg = 50%, ZNS 10 mg = 63.3%). For headache relief, ZNS 10 mg separated from placebo at 10 minutes (24.5% vs 10%). Zolmitriptan 5 mg separated from placebo at 20 minutes (38.5% vs 20%). For pain-free status, ZNS 10 mg was superior to placebo at 15 minutes (22.0% vs 6%). Both doses had higher pain-free rates than placebo at 30 minutes (placebo = 20%, ZNS 5 mg = 38.5%, ZNS 10 mg = 46.9%). Side effects were mild and seen in 16% of those attacks treated with placebo, 25% of attacks treated with ZNS 5 mg, and 32.7% treated with ZNS 10 mg. Conclusions/Relevance: Zolmitriptan nasal spray, at doses of 5 and 10 mg, is effective and tolerable for the acute treatment of cluster headache.
