Evidence comparing pioglitazone or rosiglitazone to active controls: Harms Ten observational studies reported adverse events associated with thiazolidinediones compared 243 generic 120mg sildalis amex erectile dysfunction age 50, 256-264 with other active drugs (Table 65, Evidence Table 21). The adverse events they examined included mortality, coronary heart disease events, heart failure, cancer or adenoma incidence, edema, weight gain and progression to insulin use. Because these studies did not report results separately for pioglitazone and rosiglitazone or they included only 1 of the thiazolidinediones, they do not provide information about the comparative safety of the thiazolidinediones. They do provide information about thiazolidinediones as a class compared with other antidiabetic agents. In 2 studies, thiazolidinediones were not associated with increased mortality compared 258, 261 with other oral hypoglycemic agents. In 1 study, pioglitazone was associated with reduced 243 all-cause mortality compared with other oral antidiabetic medications. In older patients with heart failure thiazolidinediones, either alone or combined with metformin, were associated with a lower risk of death over a 15-month period compared with patients not treated with an insulin 261 sensitizer. Two studies reported the incidence of coronary heart disease events (myocardial infarction or revascularization) with thiazolidinediones compared with metformin or sulfonylureas. A good-quality study using United States health insurance data found no increased risk of coronary heart disease events in patients initiating thiazolidinedione monotherapy 257 compared with those initiating metformin plus sulfonylurea combination therapy. The other found similar risks with rosiglitazone compared with sulfonylureas, metformin, or insulin, either 262 alone or in combination. Both studies also found no increased risk in the individual components of the composite outcome with thiazolidinedione use. Observational studies comparing adverse events associated with thiazolidinediones to adverse events associated with active controls Author, Year Data source, Sample Size Population (Quality) Comparison description Main outcomes Main results Adjusted odds ratio (95% CI) TZD vs. HR with propensity 243 2009 Rosiglitazone integrated All-cause adjustment, each compared to 19,717 vs. Lewis Nested case- Adjusted OR (95% CI) of any 263 2008 control; Kaiser adenoma on first colonoscopy, TZD vs. Hospital admission for congestive heart failure was the main outcome in a fair-quality 259 cohort study that used data from a Kaiser Permanente diabetes registry. Relative to patients initiating therapy with sulfonylureas, patients initiating therapy with thiazolidinediones were no more likely to experience a hospitalization for heart failure after an average of 10. A case-control study based on Oregon Medicaid claims data, in contrast, found a trend suggesting increased risk of hospitalization for heart failure associated with exposure to 265 thiazolidinediones within the previous 60 days. Increased risk was also found with exposure to insulin and to the combination of insulin plus thiazolidinediones, but not for other oral antidiabetic agents. A series of nested case-control studies found no difference in the incidence of breast, colon, or prostate cancer associated with exposure to thiazolidinediones compared with other 260 oral diabetic medications or insulin. A case-control study found a slightly higher odds of having an adenoma on first colonoscopy for subjects with type 2 diabetes exposed to TZDs 263 compared with those not exposed to TZDs. A study conducted in 500 primary care patients in Germany found fewer patients 256 progressed to insulin therapy when taking pioglitazone than when taking a sulfonylurea. However, because this study did not control for confounders and did not clearly report its recruitment strategy and other methods, these results may have a high risk of bias. The previous Drug Effectiveness Review Project TZDs report identified 43 additional 266-303 uncontrolled studies of adverse events associated with individual thiazolidinediones. The results of these studies were consistent with evidence from randomized controlled trials and comparative observational studies. Conclusions that can be drawn from this body of evidence are limited because the studies do not provide information about comparative harms. Fixed-dose Combination Products (FDCPs) or Dual Therapy Summary of findings for Fixed Dose Combination Products or Dual Therapy: Harms Harms in children • We did not find any evidence meeting inclusion/exclusion criteria for children. Harms in adults • We found no head-to-head trials that compared harms between any 2 FDCPs (insufficient strength of evidence). Rates of gastrointestinal adverse effects with Avandamet or dual therapy were high (28 to 47%), but were the same or slightly lower than those with metformin monotherapy (moderate strength of evidence). The 2 included trials were a 28 week trial (N=874) comparing 2 dosages of Avandaryl with glimepiride monotherapy and rosiglitazone monotherapy, and a 20 week trial (N=40) comparing concurrent use of rosiglitazone and glimepiride with rosiglitazone monotherapy. Evidence was limited to 1 trial (N=1,091, with outcomes reported at 24 and 54 weeks) including dual 31, 32 therapy with sitagliptin and metformin. Rates were slightly higher for sitagliptin 100 plus metformin 1000 compared with sitagliptin 100 monotherapy or with metformin 1000 monotherapy at 24 weeks (17.

Because of the progressive nature of diabetes generic 120 mg sildalis mastercard erectile dysfunction treatment nhs, practitioners and patients experience challenges in reaching and sustaining American Diabetes Association goals order 120 mg sildalis impotence definition inability. In fact, it is estimated that more than 50% of persons with type 2 diabetes will require more than one oral hypoglycemic agent after 3 years of diagnosis and approximately 70% will require combination oral therapy with or without 3 insulin 6 to 9 years from diagnosis. Within the last 1 to 2 years, three new antihyperglycemic agents have been approved: pramlintide, exenatide, and sitagliptin (Table 1). These agents offer mechanisms of glycemic control beyond that of “traditional” oral agents and insulin by targeting alternate gluco- regulatory receptors and hormones such as amylin, glucagon-like peptide-1 (GLP-1), glucose- dependent insulinotropic peptide (GIP), and dipeptidyl peptidase-4 (DPP-4). Amylin is a neuroendocrine hormone co-secreted with insulin from beta cells in response to elevated blood glucose concentrations and complements the actions of insulin. GLP-1 and GIP are secreted by L-and K-type cells in the intestinal tract in response to a combination of endocrine and neural signals initiated by the entry of food into the gut. Both endogenous GLP-1 and GIP are rapidly degraded by the proteolytic enzyme DPP-4. Diabetes Page 6 of 99 Final Report Drug Effectiveness Review Project Table1.

Diabetes Page 8 of 99 Final Report Drug Effectiveness Review Project Scope and Key Questions The purpose of this review was to compare the effectiveness and harms of newer diabetes medications for persons with diabetes mellitus. The key questions for this review were developed with input from experts in the fields of endocrinology and internal medicine. The Oregon Evidence-based Practice Center wrote preliminary key questions and identified the populations, interventions, outcomes of interest, and the eligibility criteria for studies. The key questions were reviewed and revised by representatives of organizations participating in the Drug Effectiveness Review Project. The participating organizations of the Drug Effectiveness Review Project were responsible for ensuring that the scope of the review reflected the populations, drugs, and outcome measures of interest to clinicians and patients in their constituencies. The participating organizations approved the following key questions to guide this review: Pramlintide: Key Questions 1. For children and adults with type 1 diabetes does pramlintide differ in efficacy, effectiveness, or harms in achieving glycemic control when added to prandial insulin compared with conventional insulin therapy? For children and adults with type 2 diabetes does pramlintide differ in efficacy, effectiveness, or harms in achieving glycemic control when added to prandial insulin compared with conventional insulin therapy with or without concurrent oral hypoglycemic agents? Are there subgroups of patients for which pramlintide is more or less suitable than other hypoglycemic agents? For children and adults with type 2 diabetes does exenatide differ in efficacy, effectiveness, or harms in achieving glycemic control compared with other hypoglycemic agents as monotherapy or combined therapy?
