Drugs for fibromyalgia 18 of 86 Final Original Report Drug Effectiveness Review Project Key Question 1. For adults with fibromyalgia, what is the comparative effectiveness/efficacy of included interventions? Summary of Findings General We found no eligible studies of treatment for fibromyalgia with desipramine, imipramine, desvenlafaxine, venlafaxine, escitalopram, fluvoxamine, sertraline, mirtazapine, bupropion, nefazodone, carbamazepine, divalproex, ethotoin, lacosamide, lamotrigine, levetiracetam, oxcarbazepine, phenytoin, tiagabine, topiramate, valproic acid, or zonisamide We found no eligible studies of included interventions when used as adjunctive therapy. Direct evidence There was low-strength evidence that immediate-release paroxetine is superior to amitriptyline in reducing pain (−28% compared with −1%; z= −5. Indirect evidence Pooled analysis All trials included used the drugs as monotherapy and no trial evaluated the effectiveness of the drugs as adjunctive therapy Pain, 50% response rate, Patient Global Impression of Change: Pooled analysis of placebo-controlled trials of amitriptyline, pregabalin, milnacipran, and duloxetine found that all drugs were superior to placebo Fatigue: Pooled analysis of placebo-controlled trials of amitriptyline, pregabalin, and milnacipran found that these drugs were superior to placebo for short-term results, but not in longer-term trials of 24 to 28 weeks in duration. Indirect meta-analysis Pain: Indirect meta-analysis of short-term trials (8-15 weeks) of amitriptyline, pregabalin, milnacipran, and duloxetine on measures of pain found that duloxetine was superior to milnacipran (mean difference, −0. Comparisons to placebo • Gabapentin significantly improved pain severity and response, overall impact of fibromyalgia, global status, and sleep, but not tender point pain threshold, depression or overall quality of life • Compared with placebo, a significant reduction in pain severity was only found with cyclobenzaprine in 1 of 3 trials • Among selective serotonin reuptake inhibitors, only fluoxetine, at a higher dose (45 mg), resulted in significantly greater improvements than placebo in pain, fatigue, and Fibromyalgia Impact Questionnaire Total Score • Controlled-release paroxetine did not significantly decrease pain, disability, or depressiveness or increase the number of patients with a 50% or greater response, but did significantly decrease the Fibromyalgia Impact Questionnaire Total Score, fatigue, and improved global status • Citalopram did not significantly improve pain or fatigue and only reduced depression and improved sleep in 1 of 2 trials. Detailed Assessment Direct evidence Direct evidence regarding the comparative effectiveness among included interventions was limited and only available from 4 small randomized controlled trials that compared amitriptyline 43 44 45 to cyclobenzaprine (N=208), fluoxetine (N=31), nortriptyline (N=118), and immediate- 46 release paroxetine (N=68). All patients met the American College of Rheumatology 1990 criteria for classification of fibromyalgia. Three trials reported duration of fibromyalgia, which 46 43 ranged from 36 months to 101 months. Participants were 95% female with mean ages ranging 46 45 from 36 years to 53. Race was 100% Caucasian in the fluoxetine trial conducted in 44 45 Massachusetts, 62% Caucasian and 38% non-Caucasian in the Brazilian trial of nortriptyline, 43 and was not reported in the Canadian study of cyclobenzaprine or the Turkish study of 46 43, 45 immediate-release paroxetine. Trial settings included outpatient rheumatology clinics and a 44 46 tertiary referral center, but was not well described in the Turkish study. Trial durations ranged 44, 46 43 44, 45 46 from 6 weeks to 6 months. Mean dosages for the comparator drugs were 20 mg for cyclobenzaprine, 20 mg for fluoxetine, 20 mg for immediate-release paroxetine, and 25 mg for nortriptyline. The main limitation of the poor-quality trial was that its analyses excluded a large proportion of the data – Drugs for fibromyalgia 20 of 86 Final Original Report Drug Effectiveness Review Project over one-third; consequently, its results will not be discussed here, but can be found in Evidence 44 Tables 1 and 2. However, differences between immediate-release paroxetine and amitriptyline were not significant for change in fatigue (−9% compared with −5%; z=0. Otherwise, the remaining 2 trials provided low-strength evidence of no significant 43 45 differences between amitriptyline and cyclobenzaprine or nortriptyline in any efficacy outcomes. The 2 head-to-head trials were inconsistent in their methods for assessing all efficacy outcomes. Compared with amitriptyline, similar reductions were found for cyclobenzaprine in visual analog scores for pain (−33% compared with −28%) and fatigue (−33% compared with −32%), McGill Pain Questionnaire Pain Rating Index scores (−32% compared with −31%), Depression Scale scores from the Arthritis Impact Measurement Scale (−25% compared with −20%), and in the Health Assessment Questionnaire Disability Index (−15% for both drugs). Similar proportions of patients were classified as responders based on meeting at least 4 of the following 6 criteria: 50% improvement in pain, sleep, fatigue, patient global assessment, or physician global assessment, and increase of 1 kg in mean total myalgic score (33% compared 43 with 36%). Also compared with amitriptyline, similar reductions were found for nortriptyline in mean number of tender points (−3 compared with −2. We found 5 systematic reviews that assessed multiple drugs for the treatment of 47-51 47-50 fibromyalgia. Four reviews were graded as good quality and 1 was graded as fair 47 quality. Only 1 of these reviews performed an indirect meta-analysis to compare the effectiveness between duloxetine, milnacipran, and pregabalin in fibromyalgia from placebo- 49 controlled trials of individual drugs.
Eszopiclone 90 In a 6-month placebo-controlled trial of eszopiclone 3 mg purchase levothroid 50mcg on-line thyroid cancer questions and answers, the rate of serious adverse events was 2 generic 200 mcg levothroid amex thyroid nodules causes. The most common serious adverse events were gastrointestinal disorder (0. After discontinuation of the drug, similar overall rates of “new” events (defined as either not seen during the treatment period or worsening after the treatment period) were seen in placebo (10. There were no reports of seizures, hallucinations, or perceptual-disturbance events. The most common adverse event was unpleasant taste (26. Over 6 months, the rate of discontinuation due to adverse events was 12. The most common reasons for discontinuation were somnolence (2. All patients who completed the double-blind phase were eligible to participate in the open-label extension. Of the 788 patients enrolled in the 6-month double-blind phase, 471 patients continued into the 6-month open-label extension study (59. Improvements in sleep outcomes were sustained; rebound 108 insomnia and withdrawal effects were not reported. The most common treatment-related adverse events were unpleasant taste (6. A more recently published 6-month study of nightly treatment with eszopiclone 3 mg was 119 conducted in 828 patients with chronic insomnia. Rates of withdrawals due to adverse events were similar in the eszopiclone (9%) and placebo (8%) groups. By the end of the study, 37% of eszopiclone and 52% of placebo patients withdrew. There were more reports of somnolence, unpleasant taste, and myalgia in the eszopiclone group than the placebo group. There was no evidence of withdrawal symptoms or rebound insomnia. Zaleplon 12 A one-year open-label extension of a head-to-head trial was conducted to assess the longer- 128 term safety of zaleplon 5 mg in older patients. In order to qualify for the extension phase, patients must have completed the trial and a 7-day placebo run-out without adverse effects. Thus this extension was limited to a sample of patients highly selected to be less likely to experience discontinuation effects. Sixty-four percent of patients who completed the 2-week trial enrolled in the extension study. Results of this open-label extension are reported in combination with those of an extension of a different, unpublished trial, also conducted in older people. The most frequent adverse events were headache (27%) and infection (13%). The most frequent adverse events resulting in discontinuation were pain (5%), somnolence or dizziness (4%), and gastrointestinal disturbance (2%). There was a significant increase in sleep latency, number of Insomnia Page 36 of 86 Final Report Update 2 Drug Effectiveness Review Project awakenings, and reduced total time slept on the first night after discontinuation, but these did not approach original baseline levels. Zolpidem Two open-label studies in general practice patients in France assessed the safety of 6 months of 137, 142 137 treatment with zolpidem. One looked at zolpidem 10 mg or 20 mg in 96 patients over age 40. All 96 patients were followed for 6 months; 49 of these patients continued treatment for an additional 6 months. Four of the 49 patients who continued treatment after 6 months withdrew (8%); two experienced nightmares, but these were not considered to be related to the study drug. In the second study, 107 patients were enrolled, and 20 patients withdrew before 6 months (18. Adverse events included malaise (5 events), vertigo (5 events), and anterograde amnesia (5 events). Patients experiencing vertigo and confusion were all over age 70. There was no evidence of tolerance over the 6-month course of the study, and no rebound insomnia.

Growth retardation in children Theevidenceofclinicalgrowtheffects comes from 4 randomized double-blind placebo- 114 discount levothroid 100 mcg amex thyroid and weight gain, 115 buy levothroid 100mcg lowest price thyroid cancer update, 117, 121, 123, 124 controlled trials and 2 observational studies. Changes were reported from baseline in statural growth, although the reporting methods varied somewhat among the studies. We excluded studies that only reported growth outcomes as measured using knemometry or hypothalamic-pituitary-adrenal (HPA) axis function. The use of short-term lower-leg growth rates measured with knemometry methods is less predictive of long-term growth due to the 115 inconsistent and irregular timing of growth spurts in childhood. Many studies of nasal corticosteroids have included the assessment of hypothalamic-pituitary-adrenal (HPA) axis function in order to determine the systemic effects, however the FDA has suggested that childhood growth may be a more sensitive indicator of these systemic adverse effects than the 117 HPA axis function. Growth effects of beclomethasone AQ 168 mcg, fluticasone AQ 200 mcg, and mometasone 100 mcg were each compared to placebo, respectively, in 12-month randomized 114, 115, 117 114 controlled trials of children. Beclomethasone was associated with a significantly higher risk of growth reduction (Table 14). The study of mometasone 100 mcg compared with placebo also showed no significant 117 differences in mean height increase over 1 year. We are aware of unpublished interim results from a randomized open-label 52-week comparison of budesonide aqueous to cromolyn sodium in children with perennial rhinitis that suggest some progressive slowing of growth in the budesonide group (http://www. Evidence from observational studies is inconsistent with the placebo-controlled trials. A retrospective study of 60 children (Age 24-117 months, mean age 70 months) taking beclomethasone aqueous 336 mcg/day for confirmed perennial rhinitis investigated medium and 123 long-term growth and found no adverse growth effects. It should be noted that this study was unable to determine compliance rates from the clinical records and the children were allowed to take other antiallergic medication (antihistamines and decongestants) as needed. Anotherobservationalstudyexaminedlong-term growth rates in 73 children using 121 budesonide over a period of 24 months. They assessed growth by comparing mean height to height predicted at entry. Changes in predicted mean heights after 12 and 24 months were not statistically significant. NCS Page 38 of 71 Final Report Update 1 Drug Effectiveness Review Project Table 14. Summary of growth outcomes Study Sample size Interventions Mean age (Total daily dose) % female Duration Outcome Results Beclomethasone aqueous Skoner, 2000 (336 mcg) compared with N=80 placebo Mean change in height 5. Are there subgroups of patients based on demographics (age, racial groups, gender), other medications, or comorbidities, or in pregnancy and lactation for which one nasal corticosteroid is more effective or associated with fewer adverse events? No studies stratified or analyzed data by subgroups of patients based on demographics, use of concomitant medications, or comorbidities. Race was only reported in one-third of all 14, 19, 23, 25-27, 54, 97, 103, 113 head-to-head trials and was predominantly Caucasian. Use of other concomitant nasal medications and/or presence of other concurrent nasal pathologies (e. Given NCS Page 39 of 71 Final Report Update 1 Drug Effectiveness Review Project these limitations, the demographic, concomitant medication usage, and comorbidity data provided can only be useful in determining the generalizability of results, but do not provide many insights into potential differences in efficacy or adverse events. Demographics Most head-to-head trials conducted in adults were comprised of comparable proportions of males (52%) and females (48%) and mean age overall was 33. One 4-week trial of mometasone 100 or 200 mcg and beclomethasone 400 mcg involved 477 adults with seasonal allergic rhinitis that were almost all 29 male (91. Indirect comparisons suggest that physician ratings of improvement and changes in total symptom scores were similar in this trial to other similar trials with higher proportions of female participants. In another trial of flunisolide 200 mcg compared with beclomethasone 400 mcg in adults with seasonal allergic rhinitis and a noticeably higher mean age of 66. It is not possible to draw conclusions about potential differential effects based on age using data from this trial, as the lower rates could also have been due to the use of a more stringent definition of improvement (total compared with significant). With regard to race, 1 study compared the adverse sensory attributes of fluticasone, mometasone, and triamcinolone in 364 adults with perennial allergic rhinitis who were all of 101 Asian descent. It is not possible to compare treatment effects in this trial to those reported in other similar head-to-head trials due to heterogeneity in outcome reporting. The only other evidence of safety and efficacy in an elderly population (65-87 years) with perennial allergic rhinitis was found in an unpublished 12-week placebo-controlled trial of mometasone identified in our dossier review. Mometasone 200 mcg/day was found to be significantly more effective than placebo in reducing total nasal symptom scores in the first 2 weeks.
