OBJECTIVE: To investigate whether the intensity of triptan and ergotamine use, in specific overuse, is associated with the risk of ischemic complications. METHODS: We conducted a retrospective nested case-control study using data from the PHARMO Record Linkage System. All patients with more than one prescription for either a triptan or ergotamine were initially identified. Cases were all patients who were admitted to the hospital for an ischemic complication. Matched controls were assigned the same index date as the cases. The determinant was the intensity of use of triptans and ergotamine during 1 year preceding the index date. OVERUSE WAS DEFINED AS USE OF > OR =90 DEFINED DAILY DOSES DURING THAT YEAR. Conditional logistic regression was used to estimate odds ratios (ORs), adjusting for confounders. Stratified analysis was used to estimate the risk for both patients using and those not using cardiovascular drugs. RESULTS: A total of 17,439 patients received more than one prescription. A total of 188 cases and 689 controls were identified. Triptan overuse was not associated with an increased risk of ischemic complications (OR 0.96; 95% CI: 0.49 to 1.90). Overuse of triptans in patients concomitantly using cardiovascular drugs did not increase this risk. Overuse of ergotamine turned out to be a risk factor for ischemic complications (OR 2.55; 95% CI: 1.22 to 5.36). Patients overusing ergotamine and concomitantly using cardiovascular drugs were at highest risk (OR 8.52; 95% CI 2.57 to 28.2).
CONCLUSIONS: IN GENERAL PRACTICE, TRIPTAN OVERUSE DOES NOT INCREASE THE RISK OF ISCHEMIC COMPLICATIONS. OVERUSE OF ERGOTAMINE MAY INCREASE THE RISK OF THESE COMPLICATIONS, ESPECIALLY IN THOSE SIMULTANEOUSLY USING CARDIOVASCULAR DRUGS.

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.
