A Phase I, Open-Label, Single-Dose Safety, Pharmacokinetic, and Tolerability Study of the Sumatriptan Iontophoretic Transdermal System in Adolescent Migraine Patients.

OBJECTIVE: To evaluate the safety, tolerability, and pharmacokinetics of sumatriptan delivered by the iontophoretic transdermal system (TDS) in adolescent patients. BACKGROUND: Since nausea can be a prominent and early symptom of migraine, nonoral treatment options are often required. Sumatriptan iontophoretic TDS is approved for the acute treatment of migraine in adults. The present study evaluates the pharmacokinetics of sumatriptan administered via the iontophoretic TDS in adolescents, contrasting the findings with historical data from adults. DESIGN: Patients aged 12-17 years (inclusive) with acute migraine were treated with sumatriptan iontophoretic TDS for 4 hours. Blood samples for pharmacokinetic profiling of sumatriptan were obtained prior to dosing and at predetermined time points covering the 12 hours postonset of treatment. Key pharmacokinetic endpoints included Cmax (peak plasma drug concentration), tmax (time to Cmax ), AUC0-∞ (area under the plasma concentration-time curve from time 0 to infinity), and t½ (terminal elimination half-life). Safety was evaluated by monitoring of adverse events in addition to laboratory and clinical assessments. RESULTS: The sample consisted of 37 patients, and 36 were included in the PK evaluable population. Cmax , tmax , AUC0-∞ , and t½ values were all similar between male and female patients and between younger (12-14 years) and older (15-17 years) adolescents. When compared with historical adult data, adolescent patients demonstrated similar systemic exposures to those observed in adults (mean Cmax 20.20 (±6.43) ng/mL in adolescents vs 21.89 (±6.15) ng/mL in adults; mean AUC0-∞ 98.1 (±28.1) ng·h/mL in adolescents vs 109.7 (±26.1) ng·h/mL in adults). All adverse events were mild or moderate, with application-site paresthesia being the most common (32%). No clinically relevant changes in laboratory values, vital signs, or electrocardiogram findings were observed. CONCLUSIONS: The iontophoretic TDS produced mean systemic exposures to sumatriptan in younger and older adolescents, in line with what was seen in adult subjects. It was generally well tolerated.

Assessment of provider attitudes toward #naloxone on Twitter.

BACKGROUND: As opioid overdose rates continue to pose a major public health crisis, the need for naloxone treatment by emergency first responders is critical. Little is known about the views of those who administer naloxone. The current study examines attitudes of health professionals on the social media platform Twitter to better understand their perceptions of opioid users, the role of naloxone, and potential training needs. METHODS: Public comments on Twitter regarding naloxone were collected for a period of 3 consecutive months. The occupations of individuals who posted tweets were identified through Twitter profiles or hashtags. Categories of emergency service first responders and medical personnel were created. Qualitative analysis using a grounded theory approach was used to produce thematic content. The relationships between occupation and each theme were analyzed using Pearson chi-square statistics and post hoc analyses. RESULTS: A total of 368 individuals posted 467 naloxone-related tweets. Occupations consisted of professional first responders such as emergency medical technicians (EMTs), firefighters, and paramedics (n = 122); law enforcement officers (n = 70); nurses (n = 62); physicians (n = 48); other health professionals including pharmacists, pharmacy technicians, counselors, and social workers (n = 31); naloxone-trained individuals (n = 12); and students (n = 23). Primary themes included burnout, education and training, information seeking, news updates, optimism, policy and economics, stigma, and treatment. The highest levels of burnout, fatigue, and stigma regarding naloxone and opioid overdose were among nurses, EMTs, other health care providers, and physicians. In contrast, individuals who self-identified as "naloxone-trained" had the highest optimism and the lowest amount of burnout and stigma. CONCLUSIONS: Provider training and refinement of naloxone administration procedures are needed to improve treatment outcomes and reduce provider stigma. Social networking sites such as Twitter may have potential for offering psychoeducation to health care providers.

Consistency of response to sumatriptan/naproxen sodium in a randomized placebo-controlled, cross-over study for the acute treatment of migraine in adolescence.

A multi-centered, randomized, placebo-controlled, early intervention, cross-over study was conducted to evaluate the consistency of response of sumatriptan/naproxen sodium 85/500 mg (S/NS) over 4 attacks in the acute treatment of migraine in adolescents. Inclusion of subjects was dependent on their age of 12-17 years, frequency, and history of migraine headaches (1-8 per month) over the previous 6 months prior to screening and generally healthy males and females of non-childbearing potential that were not on excluded medications. Subjects were instructed to treat within 1 hour of pain onset, including when the pain was still mild. Subjects were randomized in a double-blind fashion using a computer-generated randomization list in which the study drug was prepared prior to study start, and subjects were allocated to a number in sequential order for each site. Each site was allocated number blocks in sets of 10 depending of the rate of enrollment. The objective of this study was to examine the efficacy of S/NS vs placebo in the primary end-points of pain-free response at 2 hours (2hPF), 24-hour sustained pain-free response (24hPF), and pain-free response at 2 hours with early intervention (2hPFE) calculated as percentage out of all attacks. In the study, 94 subjects treated 347 attacks in total: treating 277 with S/NS and 70 with placebo. Compared with placebo, S/NS produced higher 2hPF rates (S/NS 37%, placebo 18%; P < .004), and 2hPFE with rates (S/NS 32%, 18% placebo; P < .03). Compared with placebo, 24hPF rates were S/NS 86%, placebo 78%, P < .17, which were higher than placebo but not clinically significant. 2hPF was reported in at least 2 of the 3 migraines treated with S/NS in 40.4% of subjects. 24hPF was reported in at least 2 of the 3 migraine treated with S/NS in 86.2% subjects. Adverse reactions were generally low and comparable between S/NS and placebo.

Pharmacokinetics and tolerability of rizatriptan in pediatric migraineurs in a randomized study.

OBJECTIVE: To evaluate the pharmacokinetic profile and tolerability of single doses of rizatriptan oral disintegrating tablets (ODTs) in pediatric migraineurs. BACKGROUND: Acute migraine treatment options for children are limited despite a rising migraine prevalence. No triptans are approved in those under 12, and only sumatriptan nasal spray (European Union) and almotriptan tablets (USA) are approved for those aged 12-17. Appropriate dose selection based on body weight may be a factor in establishing treatment efficacy in this population. METHODS: Randomized, double-blind, placebo-controlled, parallel group, single-dose study in 6- to 17-year-old migraineurs. The study was performed between acute migraine attacks. Subjects were allocated to 1 of 2 groups based on body weight: (1) those weighing <40kg received rizatriptan ODT 5mg or placebo; (2) those weighing ≥40kg received rizatriptan 10mg ODT or placebo. Pharmacokinetic data were compared with historical data on rizatriptan ODT 10mg in healthy adults. RESULTS: The geometric mean area under the plasma concentration-time curve from time 0 to infinity (AUC((0-∞)) ) (hours·ng/mL) and maximum peak plasma concentration (C(max) ) (ng/mL) were 56.68 (95% confidence interval [CI]: 48.60, 66.09) and 22.39 (95% CI: 17.90, 28.02), respectively, for the <40kg group and 78.49 (95% CI: 68.93, 89.38) and 22.27 (95% CI: 18.43, 26.92), respectively, for the ≥40kg group. For the comparison of children vs adults, the geometric mean ratios for rizatriptan AUC((0-∞)) and C(max) were 0.85 (90% CI: 0.73, 0.98) and 1.07 (90% CI: 0.86, 1.34), respectively, for the <40kg group vs historical adult data and 1.17 (90% CI: 1.02, 1.34) and 1.06 (90% CI: 0.87, 1.30), respectively, for the ≥40kg group vs historical adult data. There were no serious adverse events, and rizatriptan was generally well tolerated. CONCLUSIONS: In pediatric migraineurs, a weight-based dosing scheme generated plasma rizatriptan AUC((0-∞)) and C(max) values that were generally similar to those historically observed in adults administered a 10-mg dose of rizatriptan ODT (a proven effective dose). The data support further evaluation of the safety, tolerability, and efficacy of this rizatriptan dosing scheme in larger scale clinical trials in the pediatric migraineur population.

Long-term evaluation of sumatriptan and naproxen sodium for the acute treatment of migraine in adolescents.

OBJECTIVES: To evaluate the long-term safety, tolerability, effectiveness, impact on quality of life, and medication satisfaction of sumatriptan/naproxen sodium in the acute treatment of migraine headache in adolescents. METHODS: This 12-month, multicenter, open-label, safety study was conducted in adolescents (aged 12-17 years) with an average of 2-8 migraines/month typically lasting >2 hours untreated for >6 months prior to initiation. Subjects were instructed to treat migraines as early as possible and were allowed to rescue 2 hours post dose with a single dose of a naproxen-containing product, over-the-counter pain reliever, or anti-emetics. Subjects were advised not to take a second tablet of sumatriptan/naproxen sodium without at least a 24-hour headache-free period. Safety evaluations included adverse events, laboratory tests, and vital signs and electrocardiogram evaluation. Other evaluations included freedom from pain, quality of life, and medication satisfaction. RESULTS: Of the 656 subjects enrolled, 622 (95%) treated at least 1 migraine with sumatriptan/naproxen sodium, of which 435 (70%) and 363 (58%) completed 6 and 12 months of the study, respectively. Overall, there were 12,927 exposures to sumatriptan/naproxen sodium: on average 2.5 tablets were taken per month per subject. The most common treatment-related adverse events were nausea (7%), dizziness (3%), muscle tightness (3%), and chest discomfort (3%). There were no deaths; 4 subjects had 5 serious adverse events (suicide attempt, hemolytic anemia and syncope, suicidal ideation, spontaneous abortion) unrelated to sumatriptan/naproxen sodium and resolved without sequelae. Seven percent of subjects discontinued participation in the study because of an adverse event; 5% of subjects discontinued due to lack of efficacy. Overall, 42% of the migraine attacks were pain-free within 2 hours of treatment with sumatriptan/naproxen sodium, subjects reported improvements from baseline in 2 of 3 quality of life domains over time, and were generally satisfied with the efficacy and overall treatment at the end of the study. CONCLUSION: In adolescent migraineurs, after up to 12 months and over 12,000 exposures to sumatriptan/naproxen sodium, there were no new or clinically significant findings in the safety parameters, including the frequency and nature of adverse events, as compared to the individual components or to the adverse event profile in adults. In addition, sumatriptan/naproxen sodium provided freedom from pain over time, improvements in quality of life and medication satisfaction.

Obesity in the pediatric headache population: a multicenter study.

OBJECTIVE: To examine the prevalence of obesity, the relationship between weight compared with headache frequency and disability, and effect of weight change on headache outcomes within a pediatric headache population. BACKGROUND: Headache and obesity are both common conditions in children and adults. Research in adults has suggested a relationship between the 2 conditions. This relationship has not yet been explored within a pediatric population. The effect of obesity and weight change on headache outcomes may have important implications for clinical care. METHOD: Data on height, weight, age, and gender, as well as headache frequency and disability, were collected on 913 consecutive patients at 7 pediatric headache centers, the body mass index (BMI) calculated and the BMI percentile determined. The same data were collected on patients seen at 3- (n = 213) and 6-month (n = 174) follow-up for comparative analysis. RESULTS: The prevalence of overweight patients at initial visit did not significantly differ from the general pediatric population. BMI percentile was significantly correlated with headache frequency and disability at initial visit, although the correlations were relatively small. For children who were obese or at risk for overweight as initial visit, change in BMI was significantly positively correlated with change in headache frequency at 3- and 6-month follow-up. CONCLUSIONS: Obesity is associated with headache frequency and disability in the pediatric headache population. For children who are overweight, weight loss can contribute to a reduction in headaches over time. Clinicians should consider child weight status in providing care for pediatric headache.

Favorable outcome of early treatment of new onset child and adolescent migraine-implications for disease modification.

There is evidence that the prevalence of migraine in children and adolescents may be increasing. Current theories of migraine pathophysiology in adults suggest activation of central cortical and brainstem pathways in conjunction with the peripheral trigeminovascular system, which ultimately results in release of neuropeptides, facilitation of central pain pathways, neurogenic inflammation surrounding peripheral vessels, and vasodilatation. Although several risk factors for frequent episodic, chronic, and refractory migraine have been identified, the causes of migraine progression are not known. Migraine pathophysiology has not been fully evaluated in children. In this review, we will first discuss the evidence that early therapeutic interventions in the child or adolescent new onset migraineur, may halt or limit progression and disability. We will then review the evidence suggesting that many adults with chronic or refractory migraine developed their migraine as children or adolescents and may not have been treated adequately with migraine-specific therapy. Finally, we will show that early, appropriate and optimal treatment of migraine during childhood and adolescence may result in disease modification and prevent progression of this disease.

Efficacy and tolerability of almotriptan in adolescents: a randomized, double-blind, placebo-controlled trial.

OBJECTIVES: To assess the efficacy and safety of almotriptan 6.25 mg, 12.5 mg, and 25 mg vs placebo for acute migraine treatment in adolescents. PATIENTS AND METHODS: In this double-blind, placebo-controlled, parallel-group, multicenter trial, 866 patients aged 12 to 17 years with a >1 year history of migraine (per International Headache Society criteria) were randomized to treat one migraine headache with almotriptan 6.25 mg, 12.5 mg, 25 mg, or placebo. The primary efficacy endpoint was headache pain relief 2 hours after dosing, adjusted for baseline severity, with absence of nausea, photophobia, and phonophobia 2 hours after dosing as coprimary endpoints. RESULTS: The 2-hour pain-relief rate was significantly higher with almotriptan 25 mg compared with placebo (66.7% vs 55.3%; P = .022). The incidence of nausea, photophobia, and phonophobia at 2 hours (adjusted for baseline pain intensity) for the almotriptan 25 mg and placebo groups was not significantly different. The 2-hour pain-relief rates (unadjusted) were significantly higher with almotriptan 6.25 mg (71.8%), 12.5 mg (72.9%), and 25 mg (66.7%) than with placebo (55.3%; P = .001, P < .001, and P = .028, respectively). Rates for sustained pain relief also were significantly greater with almotriptan 6.25 mg (67.2%), 12.5 mg (66.9%), and 25 mg (64.5%) than with placebo group (52.4%), P < .01 for the 6.25- and 12.5-mg doses and P < .05 for the 25-mg dose. Age group subanalysis demonstrated significantly greater 2-hour pain-relief rates with all 3 doses of almotriptan compared with placebo for patients aged 15 to 17 years, a significantly lower incidence of photophobia and phonophobia at 2 hours with almotriptan 12.5 mg compared with placebo for patients aged 15 to 17 years, and a significantly lower incidence of photophobia with almotriptan 12.5 mg compared with placebo for those aged 12 to 14 years. Almotriptan treatment was well tolerated, with the most common adverse events (>2%) of nausea, dizziness, and somnolence. CONCLUSIONS: Oral almotriptan was efficacious for relieving migraine headache pain in adolescents, with the 12.5-mg dose associated with the most favorable efficacy profile with respect to relieving headache pain and associated symptoms of migraine (photophobia and phonophobia). Almotriptan treatment was well tolerated in this adolescent population.

North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition consensus statement on the diagnosis and management of cyclic vomiting syndrome.

Cyclic vomiting syndrome (CVS) is a disorder noted for its unique intensity of vomiting, repeated emergency department visits and hospitalizations, and reduced quality of life. It is often misdiagnosed due to the unappreciated pattern of recurrence and lack of confirmatory testing. Because no accepted approach to management has been established, the task force was charged to develop a report on diagnosis and treatment of CVS based upon a review of the medical literature and expert opinion. The key issues addressed were the diagnostic criteria, the appropriate evaluation, the prophylactic therapy, and the therapy of acute attacks. The recommended diagnostic approach is to avoid "shotgun" testing and instead to use a strategy of targeted testing that varies with the presence of 4 red flags: abdominal signs (eg, bilious vomiting, tenderness), triggering events (eg, fasting, high protein meal), abnormal neurological examination (eg, altered mental status, papilledema), and progressive worsening or a changing pattern of vomiting episodes. Therapeutic recommendations include lifestyle changes, prophylactic therapy (eg, cyproheptadine in children 5 years or younger and amitriptyline for those older than 5), and acute therapy (eg, 5-hydroxytryptamine receptor agonists, termed triptans herein, as abortive therapy, and 10% dextrose and ondansetron for those requiring intravenous hydration). This document represents the official recommendations of the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition for the diagnosis and treatment of CVS in children and adolescents.

Atomoxetine treatment of ADHD in children with comorbid Tourette syndrome.

OBJECTIVE: This study examines changes in severity of tics and ADHD during atomoxetine treatment in ADHD patients with Tourette syndrome (TS). METHOD: Subjects (7-17 years old) with ADHD (Diagnostic and Statistical Manual of Mental Disorders, DSM-IV) and TS were randomly assigned to double-blind treatment with placebo (n = 56) or atomoxetine (0.5-1.5 mg/kg/day, n = 61) for approximately 18 weeks. RESULTS: Atomoxetine subjects showed significantly greater improvement on ADHD symptom measures. Treatment was also associated with significantly greater reduction of tic severity on two of three measures. Significant increases were seen in mean pulse rate and rates of treatment-emergent nausea, decreased appetite, and decreased body weight. No other clinically relevant treatment differences were observed in any other vital sign, adverse event, laboratory parameter, or electrocardiographic measure. CONCLUSION: Atomoxetine is efficacious for treatment of ADHD and its use appears well tolerated in ADHD patients with comorbid TS.

Survey of use of the insufflator-exsufflator in patients with spinal cord injury.

BACKGROUND/OBJECTIVE: The insufflator-exsufflator has been shown to be effective in assisting cough in individuals with spinal cord injury. However, many institutions do not use this device. The study was performed to assess use of the device and attitudes among health care providers. METHODS: We developed a questionnaire with 4 categories of questions: knowledge of the device, type of facility, clinical practice with the device, and patient and provider satisfaction. The questionnaire was mailed to members of the American Paraplegia Society. RESULTS: Eighty-six questionnaires (16%) were returned. The device was being used in 49% of the institutions. The device was most commonly used with a tracheostomy; use did not correlate with size or type of facility. Patient and provider satisfaction with the insufflator-exsufflator was high. CONCLUSIONS: The insufflator-exsufflator is used as a means of removal of secretions in approximately one half of institutions polled. Satisfaction with the device is high.

Understanding the comprehensive pediatric headache examination.

Understanding and learning how to perform a comprehensive headache examination is an important part of any pediatric practice. Developing these skills allows clinicians to better take care of their patients and, when necessary, obtain a more extensive consultation.

Acute treatment of pediatric headache in the emergency department and inpatient settings.

Migraine headache can be debilitating. If initiated early, aggressive management may prevent severe disability and failure at school. It must be noted that treatments available for use for acute migraine headache in children and adolescents are off-label. Their use is widespread, but double-blind, placebo-controlled studies are still unavailable for this age group.

Randomized trial of sumatriptan and naproxen sodium combination in adolescent migraine.

BACKGROUND: Treatment of adolescent migraine remains a significant unmet medical need. We compared the efficacy and safety of 3 doses of sumatriptan and naproxen sodium (suma/nap) combination tablets to placebo in the acute treatment of adolescent migraine. METHODS: This randomized, parallel group study in 12 to 17 year olds required 2 to 8 migraines per month (typically lasting >3 hours untreated) for ≥ 6 months. Subjects entered a 12-week run-in phase, treating 1 moderate-to-severe migraine (attack 1) with single-blind placebo. Subjects reporting headache pain 2 hours after dosing were randomly assigned into a 12-week double-blind phase, treating 1 moderate-to-severe migraine (attack 2) with placebo (n = 145), suma/nap 10/60 mg (n = 96), 30/180 mg (n = 97), or 85/500 mg (n = 152). The primary end point was the percentage of subjects pain-free at 2 hours. RESULTS: The attack 2 adjusted (age; baseline pain severity) 2-hour pain-free rates were higher with suma/nap 10/60 mg (29%; adjusted P = .003), 30/180 mg (27%; adjusted P = .003), and 85/500 mg (24%; adjusted P = .003) versus placebo (10%). Posthoc primary end-point analyses did not demonstrate differences among the 3 doses or an age-by-treatment interaction. Statistically significant differences were found for 85/500 mg versus placebo for sustained pain-free 2 to 24 hours (23% vs 9%; adjusted P = .008), 2-hour photophobia-free (59% vs 41%; adjusted P = .008), and 2-hour phonophobia-free (60% vs 42%; adjusted P = .008). Analyses of other pain, associated symptoms, rescue medication use, and health outcome end points supported higher efficacy for active doses versus placebo. All active doses were well tolerated. CONCLUSIONS: All doses of suma/nap were well tolerated, providing similarly effective acute treatment of adolescent migraine pain and associated symptoms, as compared with placebo.

Opioid use in young veterans.

PURPOSE: Data suggest an increase in prescription opioid abuse in recent years. Young veterans represent a group with major risk factors for prescription opioid abuse. The objectives of this study are: (A) to determine the prevalence of chronic opioid use in young veterans over time; (B) to describe the prescribing patterns and monitoring of chronic opioid therapy in young veterans; and (C) to assess opioid management within Veterans Affairs Palo Alto Health Care System (VAPAHCS) with an emphasis on effectiveness and safety. METHODS: This is a Veterans Affairs Research and Development (R&D) Committee and IRB-approved retrospective, single-center study of young veterans aged 18-30 years on chronic opioid therapy during the study years January 1, 2003, to October 1, 2008. A subset of the study population who were receiving long-acting opioids for a minimum of 6 months was included in the effectiveness and safety analyses. Data were obtained from the Veterans Integrated Service Network (VISN 21) data warehouse, outpatient prescription records, and from electronic chart review. RESULTS: The prevalence of chronic opioid use in young veterans has increased from 3 percent in 2003 to 4.5 percent in 2007. Patients on average were exposed to two different opioids and had three different opioid prescribers. Nearly 80 percent of the opioid prescriptions during the study were prescribed by primary care providers and less than 1 percent was from pain specialists. Only 31 percent of patients on chronic opioids had undergone urine drug testing and only 5 percent had signed opioid treatment agreements. No difference in median pain score was observed following initiation of long-acting opioid therapy, and 22 percent of patients (4 of 18) met the prespecified definition of being a responder to long-acting opioid therapy. Five patients (28 percent) on long-acting opioids experienced adverse drug reactions. CONCLUSION: The prevalence of chronic opioid use in young veterans has been on the rise in recent years. Young veterans receiving care at VAPAHCS have often had multiple opioid prescribers and have trialed multiple opioid analgesics. Many improvements in appropriate monitoring and management of these patients can be made, which may include providing more training to current staff the development of an opioid refill clinic, and greater utilization of the pain management specialists. Further larger study is warranted to identify successful strategies for improving prescribing and monitoring of opioids as well as potential predictors of response to chronic long-acting opioid therapy.

Post-traumatic headache.

Post-traumatic headaches as well as post-traumatic syndrome can occur in patients after mild, moderate, or severe traumatic brain injury. Most of the patients' symptoms clear within the first 3 to 6 months; however, there are no precise criteria for predicting the clinical outcome. The diagnostic criteria for post-traumatic headaches were defined by the International Headache Society in 2004 and are helpful for classification. Evaluation must be done on an individual basis, and patients who do not clear their symptoms may need neuroimaging. The headaches fall into the category of chronic tension-type headache as well as headaches compatible with migraine and are treated in a similar fashion. There is a small group of people who do not respond and have long-term problems. These patients may benefit from a combination of pharmacologic, nonpharmacologic, and neuropsychiatric treatment. Long-term studies are needed to help clarify the history of these patients.

Eletriptan for the acute treatment of migraine in adolescents: results of a double-blind, placebo-controlled trial.

BACKGROUND: Eletriptan is a potent 5-HT(1B/1D) agonist with proven efficacy in the acute treatment of migraine in adults. OBJECTIVE: To evaluate the efficacy and tolerability of eletriptan 40 mg versus placebo in adolescent patients (aged 12-17). METHODS: A multicenter, double-blind, parallel-group, placebo-controlled trial was conducted comparing 40 mg of oral eletriptan with placebo for the treatment of migraine in adolescent patients. The primary efficacy endpoint was 2-hour headache response, and a number of secondary endpoints were also evaluated. An exploratory analysis evaluated which clinical and demographic characteristics might be correlated with high placebo response. RESULTS: Of 274 patients who treated a migraine attack, 267 were evaluated for efficacy (n = 138 eletriptan; n = 129 placebo) at 2 hours post-dose. There was no significant difference in 2-hour headache response for eletriptan 40 mg versus placebo (57% vs 57%), and no significant improvements were observed for any of the outcomes at 1 or 2 hours post-dose. By contrast, there was a significant advantage for eletriptan 40 mg in reducing headache recurrence within 24 hours post-dose (11% vs 25%, P= .028), and post hoc analyses showed statistically significant differences for sustained headache response rates (52% vs 39%; P= .04) and sustained pain-free response rates (22% vs 10%; P= .013). The strongest clinical predictor of placebo response was triptan-naïve status (i.e., no previous use of any triptan). Eletriptan 40 mg was well tolerated in this population, and the profile of adverse events was similar to that observed in Phase III trials in adult patients. CONCLUSIONS: The high placebo response rates reported here for 1- and 2-hour outcomes are in accordance with other studies of triptans in adolescent patients. The evaluation of treatment effect in adolescent migraine might benefit from use of more stringent outcome measures, such as headache recurrence, sustained headache response, and sustained pain-free response at 24 hours post-dose.

Do children and adolescents have chronic daily headaches? Yes!

Chronic daily headaches in children and adolescents appear to have been increasing throughout the past few decades. The diagnosis, classification, treatment, and long-term prognosis continue to be poorly understood. Recent epidemiologic studies and updated classifications have been done in this area, but further work is needed to help these children.
