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.

Meta-analysis of suicidality in placebo-controlled clinical trials of adults taking bupropion.

OBJECTIVE: To assess a possible relationship between treatment with bupropion (vs placebo) and expressed suicidal ideation and behavior. DATA SOURCES: This analysis, based on the US Food and Drug Administration's (FDA's) analysis of antidepressant suicidality data, included 8,953 adult subjects receiving bupropion and 6,520 adult subjects receiving placebo from randomized, placebo-controlled trials with bupropion conducted between 1976 and 2006 across multiple indications, including major depressive disorder (MDD). A text string search of the adverse event database and case report form comments was performed to identify potential suicidal events. FDA search criteria included the following text strings: accident-, injur-, suic-, or overdos-, including all events coded as accidental overdose, attempt, cut, gas, hang, hung, jump, mutilat-, self damag-, self harm, self inflict-, shoot, slash, poison, asphyxiation, suffocation, firearm, burn, drown, gun, immolat-, and monoxide, and the following terms were added by GlaxoSmithKline to the search criteria: accident, lacerat-, MVA, and hospital. The database search included data beginning from the first dose of study medication through 1 day following the last dose. DATA EXTRACTION: Suicidal event narratives were classified using the Columbia Classification Algorithm for Suicide Assessment. Additionally, changes on rating scale items for depressed mood and suicidality were analyzed. DATA SYNTHESIS: In the MDD population, the incidence of suicidal behavior or ideation was 17/3,179 (0.53%) versus 11/2,310 (0.48%) for the bupropion and placebo groups, respectively (OR = 1.28; 95% CI, 0.59-2.86). For suicidal behavior, the incidence was 8/3,179 (0.25%) versus 2/2,310 (0.09%), respectively (OR = 3.52; 95% CI, 0.81-24.48). No suicidal behavior event was noted in the other indications, and no completed suicides were reported during treatment. No significant worsening was observed for bupropion relative to placebo on the rating scale items. No differential treatment effects were observed by gender or age; regardless of treatment, however, the 18- to 24-year-old group had the greatest odds of having a suicide event. CONCLUSIONS: Although no statistically significant differences were observed between bupropion and placebo in expressed suicidal ideation or behavior, we believe that all patients treated with antidepressants should receive careful monitoring for clinical worsening, suicidality, or unusual changes in behavior.

Bupropion extended release compared with escitalopram: effects on sexual functioning and antidepressant efficacy in 2 randomized, double-blind, placebo-controlled studies.

OBJECTIVE: To compare the effects on sexual functioning and the antidepressant efficacy of once-daily bupropion extended release (XL) and escitalopram in adults with major depressive disorder (MDD). METHOD: Adult outpatients with moderate to severe DSM-IV-defined MDD and normal sexual functioning were randomly assigned to receive bupropion XL (300-450 mg/day; N = 276), escitalopram (10-20 mg/day; N = 281), or placebo (N = 273) for up to 8 weeks in 2 identically designed, randomized, double-blind, parallel-group studies (study 1 conducted from February 6, 2003, to June 10, 2004; study 2 conducted from January 21, 2003, to June 15, 2004). Data were analyzed prospectively for each study individually, and pooled data were analyzed retrospectively. RESULTS: In both the individual studies and the pooled dataset, the incidence of orgasm dysfunction at week 8 (primary endpoint) and the incidence of worsened sexual functioning at the end of the treatment period were statistically significantly lower with bupropion XL than with escitalopram (p < .05), not statistically different between bupropion XL and placebo (p > or = .067), and statistically significantly higher with escitalopram than with placebo (p < or = .001). The percentages of patients with orgasm dysfunction at week 8 in study 1, study 2, and the pooled dataset, respectively, were 13%, 16%, and 15% with bupropion XL; 32%, 29%, and 30% with escitalopram; and 11%, 8%, and 9% with placebo. The respective percentages of patients with worsened sexual functioning at the end of the treatment period were 18%, 22%, and 20% with bupropion XL; 37%, 34%, and 36% with escitalopram; and 14%, 16%, and 15% with placebo. Mean changes in Changes in Sexual Functioning Questionnaire scores for all domains at week 8 were statistically significantly worse for escitalopram compared with bupropion XL (p < or = .05). Separation from placebo could not be established at a statistical .05 level for bupropion on 17-item Hamilton Rating Scale for Depression (HAM-D-17) total score. However, escitalopram showed statistical superiority to placebo on HAM-D-17 total score in one of the 2 studies and in the pooled data. Bupropion XL did not statistically differ from escitalopram with respect to mean change in HAM-D-17 total score, HAM-D-17 response or remission rates, percentage of patients much or very much improved on Clinical Global Impressions-Improvement scale scores, or mean changes in the Hospital Anxiety and Depression (HAD) scale total score or Clinical Global Impressions-Severity of Illness scale score at week 8. CONCLUSIONS: Bupropion XL had a sexual tolerability profile significantly better than that of escitalopram with similar HAM-D-17 remission rates and HAD total scores in patients with MDD.

Bupropion XL in adults with attention-deficit/hyperactivity disorder: a randomized, placebo-controlled study.

BACKGROUND: Data remain limited on treatment strategies for adults with attention-deficit/hyperactivity disorder (ADHD). This study evaluated the efficacy and safety of an extended-release, once-daily formulation of bupropion (XL) in the treatment of adults with ADHD. METHODS: This multisite, placebo-controlled, 8-week prospective trial evaluated 162 adult patients diagnosed with ADHD (combined and inattentive types). Subjects were treated with up to 450 mg/day of bupropion XL. The primary efficacy endpoint was the proportion of ADHD responders (defined as at least a 30% reduction in the investigator-rated ADHD Rating Scale score) at week 8 (last observation carried forward [LOCF]). RESULTS: Bupropion XL responders (53%) exceeded placebo responders (31%) (p =.004 at week 8) with a significantly greater proportion of bupropion XL responders as early as week 2 (p = .01). Treatment effect size calculated for the ADHD Rating Scale total score was .6. Bupropion XL appeared to provide sustained benefit throughout the day compared with placebo (morning p =.033, afternoon p =.004, evening p = .024). Bupropion XL was safe and well tolerated, with no serious or unexpected adverse events and a low rate of drug-related study discontinuation (5%). CONCLUSIONS: The results from this multisite study indicate that bupropion XL is an effective and well-tolerated nonstimulant treatment for adult ADHD.

The spectrum of quality-of-life impairments in recurrent geriatric depression.

BACKGROUND: Although recurrent major depression in elderly individuals is a disabling condition, only a few studies have systematically examined the magnitude and specificity of quality-of-life (QOL) impairments in such patients in comparison with matched controls or the elderly population. METHODS: We examined the variations in QOL scores of 100 elderly (age range 60-88 years) patients with moderate to severe recurrent major depression and compared them with published elderly population norms. Disease-specific Quality of Life in Depression Scale (QLDS) and generic Medical Outcomes Short Form-36 Health Survey (SF-36) QOL ratings obtained at baseline were analyzed. RESULTS: Compared with published elderly population norms, depressed subjects showed significant QOL impairments in five of eight baseline SF-36 items (p <.01). Women rated their QOL as worse than men on physical functioning and role physical (p <.01) and showed similar trends on all other QOL items. Compared with younger subjects, subjects aged older than 70 years reported lower QOL on the summary physical component (p <.01) and a trend for higher QOL on the summary mental component (p <.05) of the SF-36. Depression symptom ratings were correlated with some QOL measures, but accounted for less than 10% of the variance. CONCLUSIONS: Despite limitations, such as a cross-sectional design and indirect comparisons with norms generated from another study, our findings confirm the disabling nature of recurrent late-life depression and the importance of targeting both depressive symptoms and broader QOL outcomes in intervention trials.

Improved Health-Related Quality of Life and Reduced Productivity Loss After Treatment With Bupropion Sustained Release: A Study in Patients With Major Depression.

BACKGROUND: This open-label portion of a 2-phase study assessed the effects of the antidepressant bupropion sustained release (SR) on health-related quality of life (QOL) and workplace productivity in patients with major depression. METHOD: Patients (N = 816) with DSM-IV major depression were treated with bupropion SR, 300 mg/day, for 8 weeks. The Clinical Global Impressions scale for Improvement of Illness (CGI-I) was completed at weekly clinic visits. At baseline and week 8, QOL and productivity were assessed. QOL was assessed using the Quality of Life in Depression Scale (QLDS). RESULTS: QOL and productivity were significantly improved from baseline after 8 weeks of treatment with bupropion SR. Mean QLDS scores were 18.98 and 10.36 at baseline and week 8, respectively (mean change = 8.62; p <.001). At week 8 compared with baseline, patients working at a paid job reported missing 1.58 fewer hours of work because of depression during the past 7 days, being 14.6% more effective on the job, working at reduced effectiveness less often, and incurring 6.37 fewer hours of overall lost productivity (p <.001 each variable). Improvements in QOL and productivity were significantly (p <.001) greater in bupropion SR responders (i.e., those with CGI-I scores of "very much improved" or "much improved" during the last 3 weeks of open-label therapy) than in nonresponders. CONCLUSION: Effective treatment of major depression with bupropion SR for 8 weeks is associated with improvements in QOL and reductions in lost workplace productivity. Patients who responded clinically to bupropion SR showed significantly greater improvements in these variables than those who did not respond.
