All but 1 of these trials had sufficient data to permit a meta- 76 analysis (Figure 2); a study by Saad and colleagues did not provide a measure of dispersion order cheapest erectafil bisoprolol causes erectile dysfunction. The mean difference between groups for all good- and fair-quality studies comparing pioglitazone with placebo ranged from -3 discount erectafil on line impotence in men over 50. In other words buy erectafil without a prescription erectile dysfunction ed drugs, overall, pioglitazone improved A1c about 1. Heterogeneity among these studies was Thiazolidinediones Page 26 of 193 Final Report Update 1 Drug Effectiveness Review Project significant (P<0. Poor-quality studies produced a similar improvement in A1c compared with placebo (Table 6). Results were somewhat more pronounced when pioglitazone monotherapy was compared with placebo than when combined therapy (the addition of pioglitazone to another hypoglycemic drug) was compared with placebo added to the other hypoglycemic drug, although the differences between monotherapy and combined therapy were not significant (Table 6). In other words, the placebo group had a large increase in A1c, contributing to the large between-group difference. No co-interventions were reported that might have contributed to the marked effect noted in the treatment group. At baseline subjects were taking multiple hypoglycemic medications (including more than 30% taking insulin) which were continued during the study. Throughout the trial, investigators were required to increase all therapy to an optimum, with particular attention to reaching an A1c level below 6. In addition, despite the large sample size, confidence intervals were wide for within-group changes. These factors, in addition to the focus on optimal glycemic control in both groups, contributed to a nonsignificant (P>0. The participants in this study were fairly well controlled at baseline (mean A1c 7. These factors likely also contributed to the relatively small between-group change. The study by 78 Takagi was small and the control group also improved. In the updated review we identified 4 new placebo-controlled trials, two of combination 83, 84 85, 86 87 therapy and 2 of monotherapy, along with a no-treatment comparison study. A1c improved more than in the control group in 1 small, monotherapy study of nonalcoholic 85 steatohepatitis in persons with either type 2 diabetes or impaired glucose tolerance. In the 83 pioglitazone plus sulfonylurea arm of a study by Gastaldelli and colleagues, A1c improved more in the treatment arm (change -2. A1c did not decrease significantly compared with control in 3 small studies.

Net change is the difference in A1c between the end of the study period and baseline. Placebo-controlled trials of rosiglitazone In the original report, twenty-five trials compared the efficacy or effectiveness of rosiglitazone to placebo (Table 7 and Evidence Table 6). Four rosiglitazone studies did not provide adequate 101 information for inclusion in the meta-analysis: Honisett et al. Results are similar to those noted for pioglitazone, with a mean change in A1c for all fair-quality studies of -0. Again, heterogeneity was significant among studies and there were no significant differences between monotherapy and combined therapy. Adjusted indirect comparisons of pioglitazone and rosiglitazone revealed no significant differences between the 2 drugs for A1c (Table 8). Using meta-regression, we examined placebo-controlled trials of either pioglitazone or rosiglitazone and found no significant relationships between change in A1c and follow-up interval or funder (industry or other). When studies using combination therapy (either thiazolidinedione combined with insulin, sulfonylurea, or metformin) were examined, there were no significant differences among the various treatment combinations for change in A1c. In the updated review of placebo-controlled trials of rosiglitazone, we identified 8 new 56, 84, 105-110 84, 107, 108 84 studies, including 3 poor-quality studies. Subjects took various other oral hypologycemic agents (excluding metformin). Thiazolidinediones Page 31 of 193 Final Report Update 1 Drug Effectiveness Review Project After 1-year follow-up, A1c was significantly lower in the rosiglitazone group (adjusted mean difference -0. Attrition rates were high in both groups (35% overall), primarily due to lack of efficacy in the placebo group and to adverse events in the rosiglitazone group. However, intention-to-treat analyses were performed with 99% of the study population included. Deterioration in glycemic control, defined as the time at which the fasting plasma glucose rose to ≥ 10 mmol/L, occurred in 28. In a combination therapy, double-blind trial (N=365), both groups received combination tablets of glyburide/metformin. Addition of rosiglitazone achieved greater reduction in A1c than addition of placebo (between-group difference -1. A small (N=16) trial 108 demonstrated a decrease in A1c compared with placebo (P=0. In the rosiglitazone 84 monotherapy arm of the study A1c increased 0. Thiazolidinediones Page 32 of 193 Final Report Update 1 Drug Effectiveness Review Project Figure 2.

We did, however, include these studies for examination of effectiveness outcomes anad for examination of patient subgroups (See Key Questions 2 and 3). For the updated report, we were asked to include active-control studies for both pioglitazone and rosiglitazone for the outcome of A1c in order to update the Agency for Healthcare Research and Quality report on oral hypoglycemic agents whose search ended 28 January 2006. Bolen and colleagues concluded that there were no between-group differences between thiazolidinediones and metformin (7 randomized controlled trials) or second generation sulfonylureas (13 randomized controlled trials). Thiazolidinedione plus metformin compared with a second-generation sulfonylurea plus metformin (2 randomized controlled trials) did not show a consistent effect favoring 1 of the combinations, nor did 2 randomized controlled trials comparing thiazolidinediones compared with repaglinide.
The reported frequencies of adverse events do not suggest a difference between treatments cheapest generic erectafil uk zocor impotence. ICSs compared with Leukotriene Modifiers: Moderate Data from two good quality systematic reviews and numerous head-to-head RCTs provides (≥ 12 years) no evidence of a difference in tolerability or overall adverse events (risk of experiencing any adverse effects: RR 0 order erectafil 20 mg free shipping impotence at 35. Trials were generally not designed to compare tolerability and adverse events safe 20 mg erectafil erectile dysfunction diabetes causes. Moderate Specific adverse events reported with ICSs, such as cataracts and decreased growth (< 12 years) velocity, were not found among patients taking leukotriene modifiers. One 56-week RCT found that the mean growth rate of subjects treated with beclomethasone was 0. ICSs compared with LABAs for monotherapy: High LABAs are not recommended nor approved for use as monotherapy for persistent asthma (all ages) because they may increase the risk of asthma-related deaths. Overall evidence indicates that ICSs are safer than LABAs for use as monotherapy. Leukotriene Modifiers compared with LABAs for monotherapy: High LABAs are not recommended nor approved for use as monotherapy for persistent asthma (all ages) because they may increase the risk of asthma-related deaths. Indirect evidence indicates that leukotriene modifiers are safer than LABAs for use as monotherapy. ICS+LABA compared with ICS (same dose) as first line therapy: Moderate Results from a good quality systematic review with meta-analysis and 8 RCTs found no (≥ 12 years) difference in overall adverse events or withdrawals due to adverse events between subjects treated with ICSs plus LABAs and subjects treated with ICSs alone as first line therapy. Trials were 12-52 weeks in duration and were generally not designed to compare tolerability and adverse events. Indirect evidence from a recent systematic review that included a post- hoc analysis of data from SMART suggests that the potential increased risk of asthma- related death for those taking LABAs may be confined to patients not taking ICSs at baseline. Of note, ICS+LABA combination products are only indicated for patients not adequately controlled on other asthma-controller medications (e. Controller medications for asthma 185 of 369 Final Update 1 Report Drug Effectiveness Review Project Key Question 2. What is the comparative tolerability and frequency of adverse events for controller medications used to treat outpatients with persistent asthma? Strength of evidence Conclusions Insufficient We found no studies for this comparison that enrolled children < 12 years of age. Thus, (< 12 years) there is insufficient evidence to draw conclusions in children < 12 years of age. ICS+LABA compared with ICS (increased dose) (addition of LABA to ICS compared with increasing the ICS dose): Moderate Results from a good quality systematic review with meta-analysis and numerous RCTs (≥ 12 years) found no difference in overall adverse events or withdrawals between subjects treated with ICSs plus LABAs and subjects treated with an increased dose of ICSs. Those treated with ICSs plus LABAs had an increased rate of tremor (N = 11, RR 1. Indirect evidence from a recent systematic review that included a post-hoc analysis of data from SMART suggests that the potential increased risk of asthma-related death for those taking LABAs may be confined to patients not taking ICSs at baseline. Low Two of the RCTs enrolled an exclusively pediatric population < 12 years of age (7 included (< 12 years) some subjects < 12) and results are not necessarily applicable to pediatric populations. ICS+LABA compared with ICS (same dose) (addition of LABA to ICS compared with continuing same dose ICS): Moderate Results from a good quality systematic review with meta-analysis and numerous RCTs (≥ 12 years) found no difference in overall adverse events or withdrawals between subjects treated with ICSs plus LABAs and subjects treated with the same dose of ICSs. Although not statistically significantly different, the upper limits of the confidence intervals for tachycardia or palpitations (N = 12, RR 2. Indirect evidence from a recent systematic review that included a post-hoc analysis of data from SMART suggests that the potential increased risk of asthma-related death for those taking LABAs may be confined to patients not taking ICSs at baseline. Low Nine studies (27%) included pediatric populations under 12 years of age (< 12 years) ICS+LTRA compared with ICS (same dose): Moderate Evidence from one good quality systematic review with meta-analysis (including 27 trials) (≥ 12 years) found that the addition of LTRAs to ICSs compared to continuing the same dose of ICSs resulted in no significant differences in overall adverse events or withdrawals due to adverse events. Trials were generally not designed to compare tolerability and adverse events and many used higher than licensed doses of LTRAs. Low Evidence in children < 12 years of age is limited. Just two of the 27 trials in the systematic (< 12 years) review enrolled children. ICS+LTRA compared with ICS (increased dose): Moderate Evidence from one good quality systematic review with meta-analysis (including 27 trials) (≥ 12 years) found that the addition of LTRAs to ICSs compared to increasing the dose of ICSs resulted in no significant differences in overall adverse events or withdrawals due to adverse events. Trials were generally not designed to compare tolerability and adverse events and many used higher than licensed doses of LTRAs. Low Evidence in children < 12 years of age is limited.

What is the comparative tolerability and frequency of adverse events for controller medications used to treat outpatients with persistent asthma? Strength of evidence Conclusions Combination products (ICS/LABA) compared with LTRAs: Low ICS/LABA combinations and leukotriene modifiers have similar rates of overall adverse (≥ 12 years) events and withdrawals due to adverse events based on direct evidence from 4 short-term trials. Low One of the 4 trials enrolled subjects at least six years of age (about 15% were <12 years (< 12 years) old) and one enrolled only children ages 6 to 14 ICS+LABA compared with ICS+LTRA (addition of LABA compared with LTRA to ongoing ICS therapy): Moderate Results from a good quality systematic review with meta-analysis and six RCTs provide (≥12 years) moderate evidence that there is no difference in overall adverse events or withdrawals due to adverse events between ICS+LABA and ICS+LTRA. Trials were generally not designed to compare tolerability and adverse events. Insufficient We found no RCTs enrolling children <12 years of age; the systematic review included just (<12 years) one trial in children (that did not contribute data to the meta-analysis). Thus, there is insufficient evidence to draw conclusions in children < 12 years of age. Are there subgroups of these patients based on demographics (age, racial groups, gender), asthma severity, comorbidities (drug-disease interactions, including obesity), other medications (drug-drug interactions), smoking status, genetics, or pregnancy for which asthma controller medications differ in efficacy, effectiveness, or frequency of adverse events? Strength of evidence Conclusions Age: Differences in the efficacy, tolerability, or adverse events between children <12 years of age and adolescents or adults ≥12 are described in the body of the report (Key Questions 1 and 2) and summaries above. Children ≤ 4 years of age Insufficient We found no head-to-head studies comparing the efficacy or safety of our included drugs in this age group with older children, adolescents, or adults. Racial groups: Low A large randomized trial (26,355 subjects) comparing salmeterol with placebo (SMART) was discontinued early due to findings in African Americans, safety concerns, and difficulties in enrollment. The trial reported an increased risk of asthma-related deaths (13 compared with 3; RR 4. The increased risk was thought to be largely attributable to the African-American subpopulation. Although the study was not designed to assess subgroups, there were approximately four-fold relative increases in respiratory-related deaths or life-threatening experiences (20 compared with 5; RR 4. Gender: Insufficient We did not find any study reporting a difference between the included medications. Comorbidities: Insufficient We did not find any studies meeting our inclusion/exclusion criteria that directly compared the efficacy, effectiveness, or tolerability of our included drugs in populations with specific comorbidities. Other medications (drug-drug interactions): Insufficient We did not find any studies meeting our inclusion/exclusion criteria that examined the Controller medications for asthma 187 of 369 Final Update 1 Report Drug Effectiveness Review Project Key Question 3.
