GLP-1 Analogues segmentation by Application reveals how reimbursement codes, not just clinical efficacy, shape revenue. Type 2 diabetes remains the label that unlocks broad pharmacy benefit coverage, contributing 71 % of 2023 analogue sales; however, volume growth here is decelerating to <7 % CAGR as GLP-1 moves to earlier lines of therapy and competes with SGLT-2 inhibitors. Obesityโnow formally recognized as a chronic disease by AMA and NICEโaccounts for 29 % of sales but is expanding at 24 % CAGR, propelled by payer mandates that require >5 % weight loss for continuation; this creates a higher discontinuation hurdle, extending therapy duration and amplifying per-patient revenue. A small NAFLD/NASH segment (<1 %) exists within phase III pipelines, yet pricing remains speculative until histological endpoints are accepted by HTA bodies. Collectively, these application tiers explain why off-label use is migrating toward formal obesity indications, redistributing the market taxonomy toward higher-value, longer-treatment segments.
