Impact of chest pain on cost of migraine treatment with almotriptan and sumatriptan.

Chest-related symptoms occur with all triptans; up to 41% of patients with migraine who receive sumatriptan experience chest symptoms, and 10% of patients discontinue treatment. Thus, the cost of chest pain-related care was estimated in migraineurs receiving almotriptan 12.5 mg versus sumatriptan 50 mg. A population-based, retrospective cohort study used data to quantify the incidence and costs of chest pain-related diagnoses and procedures. An economic model was constructed to estimate annual cost savings per 1000 patients receiving almotriptan versus sumatriptan based on the reported rates of chest pain. Annual direct medical cost avoided was calculated for a hypothetical health plan covering 1 million lives. Among a cohort of 1390 patients, the incidence of chest pain-related diagnoses increased significantly by 43.6% with sumatriptan (P=.003). Aggregate costs for chest pain-related diagnoses and procedures increased from $22,713 to $30,234. Payments for inpatient hospital services, costs for primary care visits, and costs for outpatient hospital visits increased by over 100%, 53.1%, and 14.4%, respectively. The model predicted $11,215 in direct medical cost savings annually per 1000 patients treated with almotriptan versus sumatriptan. Annual direct medical costs avoided totaled $194,358, and when applied to recent estimates of 86 million lives currently covered by almotriptan treatment, translates into an annual cost savings of just under $17 million for chest pain and associated care. Thus, using almotriptan in place of sumatriptan will likely reduce the cost of chest pain-related care.

Cost savings in migraine associated with less chest pain on new triptan therapy.

OBJECTIVES: This article constructs an economic model to estimate cost of chest-pain-related care in migraine patients receiving almotriptan 12.5 mg compared with those receiving sumatriptan 50 mg. STUDY DESIGN: This population-based, retrospective cohort study used data from the MEDSTAT Marketscan database (Ann Arbor, Michigan) to quantify incidence and costs of chest-pain-related diagnoses and procedures. After a 6-month exclusion period, the study used a pre-post design, with baseline and treatment periods defined, respectively, as 5 months before and after receiving sumatriptan therapy. An economic model was constructed to estimate annual cost savings per 1,000 patients receiving almotriptan instead of sumatriptan as a function of differing rates of chest pain. Annual direct medical cost avoided was calculated for a hypothetical health plan covering 1 million lives. RESULTS: Among a cohort of 1,390 patients, the incidence of chest-pain-related diagnoses increased significantly (43.6%) with sumatriptan, from 110 during the baseline period to 158 during the treatment period (P= .003). Aggregate costs for chest-pain-related diagnoses and procedures increased 33.1%, from $22,713 to $30,234. Payments for inpatient hospital services rose 10-fold; costs for primary care visits and outpatient hospital visits rose 53.1% and 14.4%, respectively. Payments for angiography increased from $0 to $462, and costs for chest radiographs and electrocardiograms increased 58.7% and 31.2%, respectively. Sumatriptan treatment was associated with a 3-fold increase in payments for services for painful respiration and other chest pain. The model predicted $11,215 in direct medical cost savings annually per 1000 patients treated with almotriptan instead of sumatriptan. Annual direct medical costs avoided for the health plan totaled $195,913. CONCLUSION: Using almotriptan instead of sumatriptan will likely reduce the cost of chest-pain-related care for patients with migraine headaches.

Economic comparison of oral triptans for management of acute migraine: implications for managed care.

Sound, informed decision making regarding which drugs to include on a formulary should be based on the best available evidence of their clinical efficacy and incidence of adverse events. Comparative drug costs and clinical effectiveness should also be considered during the formulary development process. Clinical trials traditionally evaluate efficacy and adverse events independently, whereas effectiveness in real-life conditions is defined as some combination of efficacy and side effects. When evaluating similar medications, head-to-head efficacy and effectiveness studies are preferred. For oral triptans (serotonin 5-HT(1B,1D) receptor agonists), there are many placebo-controlled trials and several active trials that compare newer oral triptans with sumatriptan; however, there have been few comparisons of triptans in head-to-head trials. Meta-analysis is an appropriate method to evaluate multiple clinical trials critically and combine the results. A recently published meta-analysis used patient-level data to assess efficacy and adverse events across multiple triptan clinical trials. In this analysis, we combined those results with medication costs to assess the overall value among oral triptans. Using this combined approach, almotriptan was found to have the greatest economic value. It delivers comparable efficacy, placebo-like tolerability, and the highest value when compared with other triptans currently marketed in the United States.

Almotriptan versus sumatriptan in migraine treatment: direct medical costs of managing adverse chest symptoms.

OBJECTIVE: Triptans, a popular class of drugs for treatment of migraine headaches, can cause adverse events including chest symptoms. This study estimated the direct medical costs of managing chest symptoms in patients treated for acute migraine with almotriptan or sumatriptan using an economic model. METHODS: The economic model of this study combined data from a randomized clinical trial that compared almotriptan with sumatriptan and data from a practice pattern survey of physicians. The pertinent clinical evaluation period was the time immediately after administration of the first medication dose. The model was developed from the perspective of a managed care payer. RESULTS: The average direct medical cost of managing chest symptoms that appeared after the first dose of an oral triptan was $0.22 for patients treated with almotriptan and $1.64 for patients treated with sumatriptan, a difference of $1.42 per patient. CONCLUSION: Relative to sumatriptan, treatment with almotriptan is likely to reduce patient care costs associated with chest symptom adverse events.
