Pharmacological management of obesity: Current landscape and emerging therapies.

abstractObesity is now recognized as a chronic, multifactorial, and progressive disease as opposed to mere excess of body weight. It significantly increases the risk of type 2 diabetes, cardiovascular disease, metabolic-associated fatty liver disease, and mental health disorders. 2022 data reveal that nearly 3 billion individuals worldwide were living with either obesity or overweight. Pharmacological therapy has evolved remarkably. Earlier medications targeted primarily the brain's monoaminergic pathways but they were withdrawn due to safety concerns. Currently, six medications (Orlistat, Phentermine/Topiramate, Naltrexone/Bupropion, Liraglutide, Semaglutide, and Tirzepatide) are approved by the U.S. Food and Drug Administration for long-term obesity management and among these, glucagon-like peptide receptor agonists have revolutionized the therapy. The emerging pipeline is even more promising. It has new dual and triple combinations such as CagriSema, Survodutide, and Retatrutide for better efficacy and metabolic outcomes, as well as long-acting and oral formulations, which will improve adherence and accessibility. India released its new obesity guideline in January 2025, emphasizing on early pharmacotherapy initiation and the adoption of stage-based obesity classification. Together, these developments signify a transformative era in obesity care where pharmacotherapy is a powerful and evidence-based tool that, in many cases, approaches the efficacy and metabolic benefits traditionally associated with bariatric surgeries.
