Pioglitazone compared with an active control Characteristics of studies 125-140 We included 16 trials comparing pioglitazone with an active control (Tables 28 and 29) cheap kamagra soft 100mg mastercard. Seven monotherapy trials 126 generic kamagra soft 100mg otc, 130 order kamagra soft 100 mg line, 133 generic kamagra soft 100 mg otc, 135 135, 137, 139, 140 compared pioglitazone to a sulfonylurea or to metformin. Trials examining combination therapy compared pioglitazone to a sulfonylurea with both groups 125, 127-129, 131 134 receiving various oral hypoglycemic agents or insulin or metformin. Pioglitazone 132, 136, 138 was compared to metformin as add-on to other diabetic therapy in 3 trials. Drug dosing across studies was fairly consistent, with most study populations 50-60 years of age. Studies 127, 128, 130, 135, 137 ranged between 3 and 18 months; 5 trials had follow-up of greater than 6 months.

Efficacy results HbA1c results for active-control trials of pioglitazone are presented in Tables 30 and 31. Effects on HbA1c were similar between treatment groups, with no statistically significant difference noted between groups in 13 of the 16 trials. The 3 trials reporting a statistically significant difference compared pioglitazone to a sulfonylurea and reported small between-group 127, 128, 133 differences in HbA1c (0. None of the trials comparing pioglitazone to metformin reported a statistically significant difference. In a small (N=92), monotherapy study in 133 Japan, HbA1c decreased more with glibenclamide (change in HbA1c −1. In an 18-month trial of glibenclamide compared with pioglitazone in newly-diagnosed diabetic 127 subjects taking a variety of concurrent hypoglycemic agents including insulin, HbA1c improved in both groups to a similar degree to week 32, then the improvement was maintained with pioglitazone but not with glimepiride. At the final follow-up (week 72), the between-group difference (in favor of pioglitazone) was −0. In the PERISCOPE trial (N=543), greater improvement in HbA1c was reported for subjects treated with pioglitazone (−0.

Rosiglitazone compared with an active control Characteristics of studies We included 14 active-control trials comparing rosiglitazone with an active control (Tables 32 141-154 144, 148, 149, 152-154 and 33). Six of these are new to this section in this report. There were 4 147, 148 monotherapy trials comparing rosiglitazone to metformin or rosiglitazone to a 145, 147, 149 sulfonylurea. The combined therapy trials compared rosiglitazone to a sulfonylurea 141-144, 152, 154 with both groups receiving metformin or insulin or compared rosiglitazone to 151 146 metformin with both groups receiving sulfonylureas or various hypoglycemic agents. Kadoglou and colleagues compared the addition of rosiglitazone with increasing the dose of metformin for people with inadequately controlled diabetes while taking metformin 850mg daily. Across active-control studies, rosiglitazone dosing was either 4 or 8 mg daily. Follow-up 147 142, intervals ranged from 24 weeks to 4 years, with 7 trials having follow-up of 1 year or more.

Data shown are mean (SD) unless otherwise indicated. Efficacy results HbA1c results for active-control trials of rosiglitazone are presented in Tables 34 and 35. One of 147 the 14 trials, A Diabetes Outcomes Progression Trial (ADOPT), reported a statistically significantly greater improvement in HbA1c for subjects treated with rosiglitazone than those 143 treated with active controls and one reported greater improvement for the active control than for rosiglitazone. The other 12 trials reported no statistically significant difference between groups. ADOPT was a large (N=4360), multicenter, double-blind, randomized controlled trial designed to evaluate monotherapy with rosiglitazone, metformin, or glyburide. The trial reported greater improvement in HbA1c at 4 years for subjects treated with rosiglitazone than for those treated with metformin (treatment difference −0. Garber and colleagues reported greater improvement in glycemic control for subjects treated with a combination of glibenclamide 5 mg/metformin 1000 mg (once or twice daily) than for those treated with rosiglitazone 4-8 mg daily combined with metformin 1500-2000 mg daily (between-group 143 difference in HbA1c 0. Among the monotherapy trials, ADOPT (N=4360) was designed to evaluate monotherapy with rosiglitazone, metformin, or glyburide among subjects recently diagnosed (within 3 years) with type 2 diabetes and who had failed lifestyle therapy but had not started on 147 oral hypoglycemic agents.

We reviewed studies using a hierarchy of evidence approach kamagra soft 100 mg for sale, where the best evidence is the focus of our synthesis for each question buy 100mg kamagra soft mastercard, population buy cheap kamagra soft 100 mg on line, intervention kamagra soft 100 mg without prescription, and outcome addressed. Studies that evaluated one pharmacologic treatment of ADHD against another provided direct evidence of comparative effectiveness and adverse event rates. Outcomes of changes in symptoms measured using scales or tools with good validity and reliability are preferred over scales or tools with low validity/reliability or no reports of validity/reliability testing. Direct comparisons were preferred over indirect comparisons; similarly, effectiveness and long-term safety outcomes were preferred to efficacy and short-term tolerability outcomes. In theory, trials that compare these drugs to other interventions or placebos can also provide evidence about effectiveness. This is known as an indirect comparison and can be difficult to interpret for a number of reasons, primarily heterogeneity of trial populations, interventions, and outcomes assessment. Data from indirect comparisons are used to support direct comparisons, where they exist, and are used as the primary comparison where no direct comparisons exist. Indirect comparisons should be interpreted with caution. Quantitative analyses were conducted using meta-analyses of outcomes reported by a sufficient number of studies that were homogeneous enough that combining their results could be justified. In order to determine whether meta-analysis could be meaningfully performed, we considered the quality of the studies and the heterogeneity among studies in design, patient population, interventions, and outcomes. When meta-analysis could not be performed, the data were summarized qualitatively. Peer Review We requested and received peer review of the report from 2 content and methodology experts. Their comments were reviewed and, where possible, incorporated into the final document. All comments and the authors’ proposed actions were reviewed by representatives of the Attention deficit hyperactivity disorder 20 of 200 Final Update 4 Report Drug Effectiveness Review Project participating organizations of the Drug Effectiveness Review Project before finalization of the report. Names of peer reviewers for the Drug Effectiveness Review Project are listed at http://www. Public Comment This report was posted to the Drug Effectiveness Review Project website for public comment. We received comments from 6 individuals representing 5 pharmaceutical companies. RESULTS Overview Figure 1 details the results of our literature searches. Overall, we identified a total of 4269 citations from searching electronic databases, reviews of reference lists, pharmaceutical manufacturer dossier submissions, peer review, and public comment. Of these, 607 were identified in the most recent update. By applying the eligibility and exclusion criteria to titles and abstracts of all identified citations, we obtained full-text copies of 1028 citations, 129 from Update 4. After re-applying the criteria for inclusion, we ultimately included 404 publications, 60 from Update 4. Dossiers were submitted by 5 pharmaceutical manufacturers for the original review: Eli Lilly (atomoxetine HCl), McNeil (methylphenidate OROS), Novartis ® (methylphenidate HCl, Ritalin LA ), Cephalon (modafinil), and Shire US (mixed amphetamine salts, mixed amphetamine salts XR).

Data abstracted from head-to-head trials can be found in Evidence Table 1 and the relevant quality assessments in Evidence Table 2. Because there are a large number of head-to- head trials directly comparing the drugs, and indirect comparisons from placebo-controlled trials are less reliable, we have only included placebo-controlled trials of drugs for which we have limited or no head-to-head evidence. Similarly, using a “best evidence” approach, we included observational studies where we had no evidence for important outcomes such as long-term functional outcomes or duration of response. Data abstracted from placebo-controlled trials can be found in Evidence Tables 3, 5, 7, and 11 and relevant quality assessments in Evidence Tables 4, 6, 8, and 12. We included 87 observational studies (Evidence Tables 9 and 10). In adult populations (age 18 and above), we included 57 placebo-controlled trials (Evidence Tables 11 and 12) and 1 long-term observational study (Evidence Tables 15 and 16) in addition to the head-to-head trials listed in Table 3 above. Previous systematic review findings While there are a large number of reviews of pharmacotherapy for symptoms of ADHD, they are generally not comparative, include or exclude drugs that are included or excluded here, and are out of date.

The results and quality of these trials are summarized in Evidence Tables 1 and 2 kamagra soft 100mg sale. Pain Multiple measures of pain were used across studies and at variable intervals 100 mg kamagra soft mastercard. We performed our analysis based on a 10-point derivative scale as this was most consistently reported across trials and is considered a valid method of pain assessment purchase 100 mg kamagra soft free shipping. All drugs were effective in improving average pain or 24 hour recall of pain compared with placebo discount kamagra soft 100 mg on-line, with amitriptyline showing the most effectiveness (−1. Significant heterogeneity was seen with the amitriptyline (I =72. Given that the Ginsberg 1996 trial used a sustained-release formulation of amitriptyline, we repeated the analysis excluding the data from this trial and found that although the result was in the direction of improvement, the significance for amitriptyline was lost with a pooled mean difference of −0. A similar effect was seen when we repeated the analysis excluding the data from Carette 1986 which did not use the American College of Rheumatology criteria for population 2 inclusion, with a pooled mean difference of −1. They did not perform a pooled analysis due to clinical and statistical heterogeneity but did find significant improvement in pain for the trials of amitriptyline 25 mg compared with placebo, consistent with our 50 analysis. Indirect meta-analysis of all placebo-controlled trials found that there was no difference between the drugs except that duloxetine was superior to milnacipran (difference in mean difference, −0. This finding held true when the analysis was repeated, excluding the Ginsberg 1996 and the Carette 1986 trial data for amitriptyline. The 49 recent meta-analysis performed by Hauser was consistent with the finding that duloxetine was superior to milnacipran but unlike our analysis, they found that duloxetine and milnacipran were also superior to pregabalin (standardized mean difference, 1. One of the limitations of the trials was that there were multiple ways in which pain was reported in each trial, including daily and weekly symptoms as well as multiple different pain scales between trials. We analyzed average or 24-hour daily pain score, converting it to a 0-10 scale, and restricted our analysis to data 8-15 weeks in duration. It is unclear how Hauser combined the multiple reports of pain. Additionally, the median duration of the randomized phase of the trials from the Hauser meta- 49 analysis was 24 (range 6-28) weeks. When we repeated our analysis including all trial data (duration range 6-28 weeks), the superiority of duloxetine over milnacipran was lost (−0. In summary, for short-term use, there was low evidence that all drugs are superior to placebo in pain response, with no difference between the drugs except that duloxetine was superior to milnacipran. Head-to-head trials are needed to confirm these findings. Pooled effectiveness of amitriptyline, pregabalin, milnacipran, and duloxetine compared with placebo (8-15 weeks) Outcome measure Amitriptyline Pregabalin Milnacipran Duloxetine Pain Mean difference in 24-hour daily pain score converted to a −1. Drugs for fibromyalgia 24 of 86 Final Original Report Drug Effectiveness Review Project Table 4. Indirect analysis of placebo-controlled trials in fibromyalgia Duloxetine Duloxetine Duloxetine Milnacipran Milnacipran Pregabalin vs. Response Response was defined differently in all of the trials, with many of the trials having a composite response that included multiple outcome measures such as 30% or 50% reduction in pain and improvement on Patient Global Impression of Improvement or Change. Many of the trials also reported this data separately, allowing us to perform a pooled analysis and indirect meta-analysis on pain response rate. Pooled analysis of placebo-controlled trials found that all drugs were effective in achieving a 50% improvement in pain (Table 4, Figure 2). The data for amitriptyline was insufficient to determine its validity given the small number of patients from 2 trials, N=68, 54, 55 one of which used a sustained release formulation of amitriptyline. Two systematic reviews of pregabalin compared with placebo in fibromyalgia used the same 4 trials, pooled data based on dose, and found similar results on 30% or 50% pain response and for “much or very much 72, 74 improved” on Patient Global Impression of Improvement or Change. Indirect meta-analysis of the placebo-controlled trials of duloxetine, milnacipran, and pregabalin found that there was no significant difference between the drugs on ability to achieve a 50% reduction in pain (Table 4). The data for amitriptyline was too sparse for indirect comparison. We had no data on amitriptyline for the outcome of 30% improvement in pain but all of the other drugs had a small but significant improvement in 30% pain response compared with placebo and no significant difference between the drugs was found (Tables 3 and 4). This finding was consistent with the 49 Hauser, et al. Drugs for fibromyalgia 26 of 86 Final Original Report Drug Effectiveness Review Project For the outcome of any improvement on the Patient Global Impression of Improvement or Change score, a significant benefit over placebo was found for milnacipran, pregabalin, and 2 amitriptyline. However, I statistics revealed substantial heterogeneity within the milnacipran (74. When we used meta-regression to explore reasons for the heterogeneity, we found a significant association for placebo group response rate (P=0. Findings from the meta-regression indicated that trials with higher rates of improvement in the placebo group had smaller benefits with milnacipran or pregabalin. In our indirect meta-analysis, no significant differences were found between milnacipran, pregabalin, and amitriptyline.

Long-acting opioid analgesics 35 of 74 Final Update 6 Report Drug Effectiveness Review Project Different types of chronic noncancer pain patients were studied in trials buy 100 mg kamagra soft overnight delivery, including back pain cheap kamagra soft 100mg overnight delivery, osteoarthritis generic 100mg kamagra soft overnight delivery, phantom limb pain cheap 100mg kamagra soft fast delivery, and neuropathic pain. Subgroups of trials for specific types of pain had the same problems with heterogeneity in interventions, outcomes assessed, and findings that were encountered in examining general efficacy and adverse events. They were further limited by the smaller number of available trials for each type of pain. These trials provided insufficient indirect evidence that a long-acting opioid is superior to any other in any subpopulation of patients with chronic pain. SUMMARY Strength of Evidence The results of this review are summarized in Table 8, below, and Appendix E summarizes the strength of the evidence for each key question. Although we identified 10 head-to-head trials comparing 2 or more long-acting opioids, the evidence was insufficient to determine if there are differences among the drugs. Eight trials found no significant difference in pain relief or function between long-acting opioids. The 2 trials which found a significant difference (1 trial of transdermal fentanyl vs. There was also insufficient evidence to determine whether long-acting opioids as a class are more effective or associated with fewer harms than short-acting opioids. Seven fair-quality trials directly compared a long-acting opioid to a short-acting opioid. These trials were highly heterogeneous in terms of study design, patient populations, interventions, and outcomes assessed. There was fair-quality evidence from 3 more homogeneous trials to suggest that long- acting oxycodone and short-acting oxycodone are equally effective for pain control in adult patients with chronic noncancer pain. There was insufficient evidence to assess comparative effectiveness or harms in subgroups. Limitations This report was limited by a lack of good-quality direct evidence. Most included studies were relatively small, of short duration, and had important methodologic flaws. We were unable to conduct quantitative meta-analyses due to diversity among the trials in populations, outcome measures, and study designs. Methodological limitations of this review within the defined scope included the exclusion of studies published in languages other than English and lack of a specific search for unpublished studies. Applicability The trials generally provided inadequate information to accurately assess applicability or showed evidence of having highly selected populations. Most trials did not report numbers of patients screened or eligible for entry and some did not specify exclusion criteria. When exclusion Long-acting opioid analgesics 36 of 74 Final Update 6 Report Drug Effectiveness Review Project criteria were specified, patients at risk for drug or substance abuse were typically excluded from trial participation. Summary of evidence Strength of evidence Conclusions Key Question 1. What is the comparative effectiveness of different long-acting opioids in reducing pain and improving functional outcomes in adult patients being treated for chronic noncancer pain? Direct Fair to poor There was insufficient evidence from 10 head-to-head trials to suggest that evidence a long-acting opioid is superior to another in terms of efficacy in adult patients with chronic noncancer pain. Eight trials found no significant difference in pain relief or function between long-acting opioids. The 2 trials which found a significant difference (1 trial of transdermal fentanyl vs. Indirect Insufficient No useful indirect evidence for determining the comparative efficacy of long- Evidence acting opioids was found in 27 placebo-controlled trials. The studies were generally of insufficient quality and too diverse in terms of study designs, patient populations, interventions, and assessed outcomes to conduct indirect comparisons on efficacy. What is the comparative effectiveness of long-acting opioids compared with short-acting opioids in reducing pain and improving functional outcomes when used for treatment of adults with chronic noncancer pain? Direct Fair Seven fair-quality trials directly compared a long-acting opioid to a short- evidence acting opioid. There was no good-quality evidence to suggest superior efficacy of long-acting opioids as a class over short-acting opioids. For oxycodone specifically, there was fair evidence from 3 trials that long- and short-acting oxycodone are equally effective for pain control. What are the comparative harms (including addiction and abuse) of different long-acting opioids in adult patients being treated for chronic noncancer pain? Direct Fair to Poor There were insufficient data from 10 head-to-head trials of long-acting evidence opioids to conclude that any long-acting opioid is associated with fewer harms compared with others.
