This was also true in the 2 studies that investigated the same (rerandomized) population order 15 mg aristocort fast delivery allergy index nyc. Withdrawals due to adverse events were reported in 5 trials. Three favored short-acting 33, 38, 39 34 36 opioids, 1 favored long-acting, and 1 was equivocal. These data were limited by the poor quality of the trials for adverse event assessment and the fact that 2 of the trials evaluated the same (rerandomized) population.

Long-acting opioid analgesics 34 of 74 Final Update 6 Report Drug Effectiveness Review Project Key Questions 5 and 6. Are there subpopulations of patients (specifically by race, age, sex, socio-economic status type of pain, or comorbidities) with chronic noncancer pain for which one long-acting opioid is more effective or associated with fewer harms, or for which long-acting opioids are more effective or associated with fewer harms than short-acting opioids? Summary of evidence • The evidence regarding differential efficacy or adverse event risk from long-acting opioids or between long-acting and short-acting opioids in subpopulations of patients with noncancer pain was severely limited in quantity and quality and it was not possible to draw reliable conclusions regarding comparative efficacy or adverse event rates for any subpopulation from these data. Detailed assessment No clinical trials or observational studies were designed to compare the efficacy of long-acting opioids for different races, age groups, or genders. Race was rarely reported in the trials and when it was reported the overwhelming majority of patients were white. Women were well- represented in the trials (slightly over 50%). The average age of included patients was in the 47 11, 34 mid-50s, though 1 study evaluated patients with an average age of 70 years. Two trials performed very limited subgroup analysis on older patients. Neither trial directly compared a long-acting opioid to another. They provided little information regarding differential efficacy or adverse events within the class of long-acting opioids. One fair-quality retrospective cohort study found that the risk of constipation associated with long-acting oxycodone compared with transdermal fentanyl was higher in patients older than 65 years (adjusted odds ratio, 7. Because there was a high likelihood for unmeasured or unknown confounders, firm conclusions from this subgroup analysis were not possible. A post-hoc analysis of 2 placebo-controlled trials examined the effects of age, sex, and 63 prior opioid use on response to extended-release oxymorphone in patients with low back pain. Both trials included a titration phase and a 12-week, randomized treatment phase. Only those patients who responded to oxymorphone treatment in the titration phase continued into the randomization phase (347 of 575; 60. There were no significant effects of age, sex, or prior opioid experience on the visual analogue scale-measured pain intensity and no effect of the measured factors on discontinuations due to lack of efficacy in the oxymorphone group. There were no significant differences in the occurrence of adverse effects based on age or sex. Constipation occurred more frequently in opioid-naïve patients during titration, but the difference was not significant during the treatment phase. Because it included only trials of 1 drug, this analysis did not provide evidence for comparative effectiveness or safety in subgroups. 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, including back pain, osteoarthritis, phantom limb pain, 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.
In this Disease-modifying drugs for multiple sclerosis Page 58 of 120 Final Report Update 1 Drug Effectiveness Review Project analysis generic 10 mg aristocort amex allergy testing kirkland wa, we have pooled only to the same dose and dosing schedule of interferon beta-1a SC ® (Rebif ). In the head-to-head trials comparing the beta interferon products, adverse events were not 41 well reported, with 2 of the 5 trials not reporting adverse events. The dose of interferon beta-1a ® SC (Rebif ) was 22 µg weekly in the Koch-Henrisksen study and they only reported combined incidence for a few selected adverse events. Withdrawal or early discontinuation due to an adverse event or any other reason was not found to be different between this low dose of ® ® interferon beta-1a SC (Rebif ) and interferon beta-1b (Betaseron ) 250 µg. Typical adverse events reported included flu-like symptoms, injection-site reactions, fever, and withdrawal. The comparative frequency of these events is outlined in the section that follows. The Cochrane systematic review of placebo-controlled trials in patients with relapsing- remitting multiple sclerosis evaluated the frequency of adverse events, reporting only on the 44 ® µg dosing of interferon beta-1a (Rebif ) however they did include data from a once weekly dosing schedule from the OWIMS trial. Only 3 times weekly ® interferon beta-1a SC (Rebif ) was not associated with significantly increased rates of flu-like syndrome, fever, and myalgias (Table 24). The incidence of leukopenia, however, was ® significantly higher with 3 times weekly interferon beta-1a SC (Rebif ), while interferon beta-1b ® ® SC (Betaseron ) and interferon beta-1a IM (Avonex ) were not. Comparing the 2 dosing ® regimens of interferon beta-1a SC (Rebif ), dosing once weekly resulted in statistically significantly greater rates of flu-like syndrome, fever, and headache while dosing 3 times weekly ® did not. Of note, standard dosing for (Rebif ) is 3 times weekly.

Two of these trials used a ® 22 µg dose of interferon beta-1a SC (Rebif ) and for this reason we only pooled this dose for adverse event analysis. Pooled analysis of these trials suggested significantly higher rates of injection site reaction, abnormal liver function tests, and withdrawal due to adverse events with ® interferon beta-1a SC (Rebif ) 22 µg and flu-like syndrome and withdrawal due to adverse ® events with interferon beta-1b SC (Betaseron ) compared with placebo (Table 25).

There was no difference in the frequency of fatigue (relative risk, 1. Of the 5 observational studies in patients with relapsing-remitting multiple sclerosis, 3 met inclusion criteria for both effectiveness and harms analysis, and the best of these was a retrospective cohort study based on data from patients in Austria, Switzerland, and Germany, 49 with 4754 patients exposed to 1 of the 3 interferons. An analysis of the reasons for discontinuation of treatment indicated that discontinuations due to injection site reactions were ® significantly lower in the interferon beta-1a (Avonex ) 30 µg IM weekly group compared with ® either the interferon beta-1a SC (Rebif ) 22 mcg SC 3 times weekly or interferon beta-1b ® (Betaseron ) 250 µg SC every other day groups, but no different than the interferon beta-1a SC ® (Rebif ) 44µg SC twice weekly group. Differences in frequency of flu-like syndrome was ® statistically significant only for interferon beta-1a SC (Rebif ) 22 mcg group compared with the ® ® interferon beta-1b (Betaseron ) group with the interferon beta-1a SC (Rebif ) 22 mcg being ® lower. Discontinuations due to lack of efficacy was greatest in the interferon beta-1a SC (Rebif ) ® 22 mcg group, compared with the interferon beta-1a IM (Avonex ) group or the interferon beta- ® 1b (Betaseron ) group (Table 26). The other 2 studies were of patients being treated at large multiple sclerosis specialty centers (1 in Spain, 1 in Italy), enrolled and followed every 3 46, 47 months. These studies had a high risk of bias due to clinically important differences among ® groups at baseline, and because at the outset of data collection only Betaseron was marketed in ® ® those countries, while Avonex and Rebif were approved during the time period of the study.

Other non-trial evidence was limited and low quality, with 4 open-label studies of ® 133-138 interferon beta-1b (Betaseron ), 3 open-label studies of interferon beta-1a IM ® 114, 139, 140 ® 141, 142, 142 (Avonex ), 3 open label studies of interferon beta-1a SC (Rebif ), , 3 studies 143-147 (1 with 3 publications) reporting adverse event data for more than 1 beta interferon, 1 study ® 148 comparing open-label use of interferon beta-1b SC (Betaseron ) to an untreated control group, ® and 1 study comparing interferon beta-1a IM (Avonex ) to alemtuzumab, a drug not available in 149 the United States (Investigators 2008). The observational study by Rio et al provided a median of 60 months of follow-up (range 12-115 months) on 146 patients receiving interferon beta-1b ® 150 (Betaseron ).
Clinical trials are often not designed to assess adverse events buy aristocort 40mg line allergy testing ct, may select low-risk patients (in order to minimize drop-out rates), or may have too short a follow-up period in which to adequately assess safety. Observational studies designed to assess adverse event rates may include broader populations, carry out observations over a longer time period, use higher quality methodological techniques for assessing adverse events, or examine larger sample sizes. Safety and tolerability were examined using data provided on overall and serious adverse events, withdrawals due to adverse effects, and other relevant specific adverse events including hypoglycemia, liver toxicity, heart failure, pulmonary edema, weight gain, and edema. Selection criteria for the updated report For the updated report we expanded our inclusion criteria with respect to study designs for effectiveness outcomes in order to be consistent with criteria used in the Agency for Healthcare Research and Quality report. Most notably, we expanded our examination of active-control comparisons, which was previously restricted by sample size, follow-up interval, or outcomes. These criteria are listed in Table 3, where they are contrasted with those of the prior report and of the Agency for Healthcare Research and Quality report.

Data Abstraction The following data were abstracted from included trials into a relational database developed for this review: study design; setting; population characteristics (including sex, age, race/ethnicity, diagnosis, duration of type 2 diabetes, A1c, weight, and body mass index); eligibility and exclusion criteria; drug dosage and frequency; treatment duration; comparison group care; numbers screened, eligible, enrolled, and lost to follow-up; and results for each prespecified outcome. Similar data were abstracted for studies that were not controlled trials and which examined adverse events. We recorded results achieved with an intention-to-treat analytic approach, when reported. If only per protocol results were reported, we specified the nature of these results and reported them. In trials with crossover, outcomes for the first intervention were recorded if available. This was because of the potential for bias due to differential withdrawal prior to crossover, the possibility of a “carryover effect” (from the first treatment) in studies without a washout period, and a “rebound” effect from withdrawal of the first intervention. Thiazolidinediones Page 15 of 193 Final Report Update 1 Drug Effectiveness Review Project Quality Assessment We assessed the internal validity (quality) of controlled clinical trials using the predefined criteria listed in the quality assessment tool found in Appendix C. These criteria are based on 29 those used by the US Preventive Services Task Force and the National Health Service Centre 30 for Reviews and Dissemination. For each included trial we assessed methods for the following charateristics: randomization; allocation concealment; blinding of participants, investigators, and assessors of outcomes; the similarity of comparison groups at baseline; adequate reporting of attrition, crossover, adherence, and contamination; post-allocation exclusions; and use of intention-to-treat analysis. We based assessment of observational and other study designs with adverse event data on unbiased selection of patients, loss to follow-up, unbiased and accurate ascertainment of events, and control for potential confounders (Appendix C). These criteria were then used to categorize studies as good-, fair-, and poor-quality studies. Studies that had a significant flaw in design or implementation such that the results were potentially not valid were categorized as “poor”. Studies that met all quality criteria were rated good quality. As the “fair quality” category is broad, studies with this rating vary in their strengths and weaknesses. Studies were not excluded on the basis of poor quality as there is a lack of empirical evidence for a relationship between criteria thought to measure validity and actual study 31 outcomes. Studies rated as poor-quality were carefully examined and the potential sources of bias and its potential impact are presented in the evidence tables. If data were sufficient, a sensitivity analysis was performed to compare results between studies with high and low risk of bias. External validity of studies was assessed by examining the following: adequacy of population description; inclusion and exclusion criteria; and whether the treatment received by the comparison group was reasonably representative of standard practice. Systematic reviews that fulfilled inclusion criteria were rated for quality using pre- defined criteria (see Appendix C) to ensure the following: clear statement of the questions and inclusion criteria; adequate search strategy; adequate assessment of individual trials; adequate provision of information; and appropriate methods of synthesis. Data Analysis and Synthesis Important descriptive information about the population, setting, intervention, and quality assessment of studies are presented in tables, and synthesis is presented in narrative. When there were sufficient data on the primary outcome of A1c and studies were considered to be homogeneous with respect to important variables (population characteristics, drug dosage, follow-up interval, and the application of any co-intervention), we performed a meta-analysis. We also performed a meta-analysis of two key outcomes related to adverse events: the total number of withdrawals and the withdrawals related to adverse events. We recorded the mean difference between baseline and follow-up measures for control and intervention groups and the standard error of each difference.
