The Oral GLP-1 Revolution: Once-Daily Pills Reshape Obesity Treatment

A new wave of pharmaceuticals, dubbed ‘Ozempic 2.0,’ is poised to fundamentally change how obesity and Type 2 diabetes are treated, focusing on highly anticipated oral, once-daily medications. This shift promises to deliver strong results, wider access, and greater patient comfort than today’s common weekly injectable drugs like Ozempic and Mounjaro. FDA approval for these new medicines could arrive as early as 2026.
The biggest difference in this new generation of treatments, which are GLP-1 agonists, is the delivery method: a daily pill replaces the weekly injection. Eli Lilly’s experimental pill, orforglipron, is the leading candidate in this space. Lilly states that orforglipron can be taken once per day without the restriction of food and water limitations, which significantly improves accessibility and patient comfort.
These oral formulations offer considerable logistical benefits. Pills are often easier to distribute, do not require refrigeration, and could potentially make treatment more affordable for both individuals and healthcare systems globally, especially in countries where injectables are currently too costly. The manufacturer of Mounjaro, Eli Lilly, emphasized its goal to offer a convenient, once-daily pill that can be scaled globally.
In clinical trials, orforglipron demonstrated superior performance compared to Novo Nordisk’s oral semaglutide (the pill version of Ozempic). In a year-long study, patients taking the highest trial dose of orforglipron lost an average of 9.2% of their body weight, compared with 5.3% for the rival pill. Initial tests for orforglipron also showed an average weight reduction of 10.5% compared to 2.2% with a placebo.
While injectables still lead in overall weight loss (delivering 15 to 20 percent loss versus 11 to 14 percent expected from pills), researchers are already working on ways to improve oral results and reduce common side effects like nausea. For example, new hormone combinations, such as pairing semaglutide with amylin, are being explored, with early data suggesting weight loss close to 20 percent while being easier on the digestive system.
Eli Lilly Chief Scientific Officer Dan Skovronsky views the pill as having the potential to become the primary treatment for the majority of patients managing Type 2 diabetes and obesity. David Lau, an endocrinologist, noted that this newer generation of medications signifies "changes beyond what you see on the scale".
Despite the optimism and urgency from drugmakers, the anti-obesity pills remain subject to FDA approval. Furthermore, hopes for secondary benefits were tempered recently after Novo Nordisk disclosed that an oral GLP-1 drug failed to slow the progression of Alzheimer’s disease in two major trials.
If approvals move quickly, the first once-daily pills could be available in 2026, expanding metabolic disease treatment for millions worldwide.
