The limits and challenges of antiobesity pharmacotherapy

Abstract

INTRODUCTION: Pharmacotherapy is a useful adjunct when patients with obesity are unable to achieve adequate benefit from lifestyle interventions. AREAS COVERED: This review covers the history of antiobesity drugs, efficacy, and risks of currently approved drugs, limits of their usefulness in clinical practice, gaps in knowledge, methodological limitations of clinical trials, and reasons for underutilization. EXPERT OPINION: In randomized controlled trials, currently approved antiobesity drugs have yielded an average weight loss ranging from approximately 3% to 9% relative to placebo at 1 year. Inadequate inclusion of racial and ethnic minorities and men, and high dropout rates in clinical trials limit generalizability of these findings to clinical practice. Weight loss achieved with antiobesity drugs is generally associated with lowered glycemia, but improvements in blood pressure and lipid measures tend to be marginal. There is limited evidence for sustained weight loss beyond 1 year and for safety and efficacy of antiobesity drugs in children and adolescents, and in post-bariatric surgery patients. None have demonstrated reduction in major adverse cardiovascular events or other significant disease outcomes. Limited health insurance coverage and negative perceptions of physicians have hindered the utilization of antiobesity drugs.

  • In surveys, physicians and advance practice providers describe major barriers to prescribing antiobesity medications, including high costs, lack of insurance coverage, side effects, medication interactions, insufficient knowledge, lack of time for weight loss counseling, and a perceived lack of efficacy.

    “In surveys, physicians and advance practice providers describe several major barriers to prescribing antiobesity medications, including high costs and lack of insurance coverage, side effects, medication interactions, insufficient knowledge, lack of time for weight loss counseling, and a perceived lack of efficacy.”

    From Effectiveness and safety of drugs for obesity (2024) · cites this paper as [58]

    The Underutilization section reports that physicians and health care providers cite concerns about safety and effectiveness, knowledge gaps, limited experience, inadequate insurance coverage, and high costs as reasons for not prescribing antiobesity drugs. It does not identify medication interactions or lack of counseling time as prescribing barriers, nor does it specifically report these findings for advanced practice providers. (LLM, conf=0.88)

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.
