Abstract

Background & aims We performed a systematic review and network meta-analysis to evaluate the overall and comparative effects of weight-loss medications approved by the Food and Drug Administration for long-term use on cardiometabolic risk profiles of obese adults.Methods We performed a systematic literature review through February 28, 2017 to identify randomized clinical trials of the effects of Food and Drug Administration-approved weight-loss medications (ie, orlistat, lorcaserin, naltrexone-bupropion, phentermine-topiramate, and liraglutide) administered to obese adults for 1 year or more, compared with placebo or another active agent. Outcomes of interest included changes in blood glucose (fasting blood glucose [FBG] and hemoglobin A1c), cholesterol profile (low-density lipoprotein and high-density lipoproteins), blood pressure (BP; systolic/diastolic), and waist circumference (WC). We performed pair-wise and network meta-analyses with outcomes reported as weighted and standardized mean differences. Quality of evidence was rated using GRADE (Grading of Recommendations Assessment, Development and Evaluation).Results In a meta-analysis of 28 randomized controlled trials (29,018 participants; median body mass index, 36.1 kg/m 2), we associated weight-loss medications with a modest decrease in FBG (weighted mean difference, 4.0 mg/dL; 95% confidence interval, -4.4 to -3.6 mg/dL) and WC (weighted mean difference, reduction of 3.3 cm; 95% confidence interval, -3.5 to -3.1 cm), without clinically meaningful changes in systolic/diastolic BP or cholesterol profile vs placebo (standardized mean difference <0.2); effects varied among drugs. Phentermine-topiramate use was associated with a substantial decrease in WC and a modest decrease in FBG, hemoglobin A1c, and BP, and had minimal effect on cholesterol. Liraglutide use was associated with a substantial decrease in FBG, hemoglobin A1c, and WC, and a minimal effect on BP and cholesterol. Naltrexone-bupropion use was associated with moderate increase in high-density lipoprotein cholesterol, but had a minimal effect on FBG and WC. Orlistat use was associated with a decrease in low-density lipoprotein and high-density lipoprotein cholesterol. No drug improved all cardiometabolic risk factors.Conclusions In a systematic review and network meta-analysis, we found Food and Drug Administration-approved weight-loss medications to have only modest positive effects on cardiometabolic risk profile. Further research is needed to evaluate the long-term cardiometabolic benefits of these medications.Prospero CRD42016039486.

  • Previous NMAs and a traditional meta-analysis on therapeutic options for overweight and obesity did not include more recently available OMMs such as tirzepatide, or included medications not approved for overweight/obesity, or adopted different inclusion criteria.

    “Several NMAs20–23 and a traditional meta-analysis24 on different therapeutic options for overweight and obesity were published in the last few years, but they did not include more recently available OMMs, such as tirzepatide20–22, or they included medications not approved for the treatment of overweight/obesity (for example, metformin, SGLT2 inhibitors or GLP-1 agonists, such as dulaglutide)22, or”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
