总之,orforglipron和retatrutide是近年肥胖治疗领域的重大进展,这些新型药物相较于现有的减重治疗方案具有诸多显著优势,包括疗效提升、治疗反应率增加以及更优的治疗可及性,对肥胖症治疗的未来形势产生了深远的影响。为了全面评估这些药物的安全性、有效性以及长期疗效,我们亟需开展进一步的研究以及严格的监管审查。 最后,我们也应认识到,药物只是辅助减重的手段,运动、控制饮食等健康的生活方式依旧是减肥的关键。虽然GLP-RA药物的常见副作用主要为胃肠道不良反应,但在极少数情况下,这些药物与胰腺炎以及甲状腺肿瘤等更为严重的不良事件的发生相关。因此,我们应该将药物作为辅助手段,而不是完全依赖药物来解决肥胖问题。 参考资料:[1] Beyond Ozempic: brand-new obesity drugs will be cheaper and more effective,Retrieved June 28, 2023 from https://www.nature.com/articles/d41586-023-02092-9[2] Goodbye, Ozempic,Retrieved June 28, 2023 from https://www.theatlantic.com/health/archive/2023/06/ozempic-pills-obesity-drugs-semaglutide/674541/[3] Lilly's phase 2 retatrutide results published in The New England Journal of Medicine show the investigational molecule achieved up to 17.5% mean weight reduction at 24 weeks in adults with obesity and overweight,Retrieved June 28, 2023 from https://investor.lilly.com/news-releases/news-release-details/lillys-phase-2-retatrutide-results-published-new-england-journal[4] Lilly's phase 2 results published in the New England Journal of Medicine show orforglipron, a once-daily oral nonpeptide GLP-1 receptor agonist, achieved up to 14.7% mean weight reduction at 36 weeks in adults with obesity or overweight,Retrieved June 28, 2023 from https://investor.lilly.com/news-releases/news-release-details/lillys-phase-2-results-published-new-england-journal-medicine[5] Zhao, Xin et al. “GLP-1 Receptor Agonists: Beyond Their Pancreatic Effects.” Frontiers in endocrinology vol. 12 721135. 23 Aug. 2021, doi:10.3389/fendo.2021.721135[6] Rizvi, Ali A, and Manfredi Rizzo. “The Emerging Role of Dual GLP-1 and GIP Receptor Agonists in Glycemic Management and Cardiovascular Risk Reduction.” Diabetes, metabolic syndrome and obesity : targets and therapy vol. 15 1023-1030. 5 Apr. 2022, doi:10.2147/DMSO.S351982[7] Scheen, André J. “Dual GIP/GLP-1 receptor agonists: New advances for treating type-2 diabetes.” Annales d'endocrinologie vol. 84,2 (2023): 316-321. doi:10.1016/j.ando.2022.12.423
