What does Orforglipron do? Benefits and evidence

Orforglipron is a small molecule, not a peptide. The FDA approved Foundayo tablets for adult weight management in April 2026. Large trials show weight loss and better blood sugar control. Stomach upset is common, and interactions with other medicines matter.

• Foundayo tablets are approved for long-term weight management in adults with obesity, or overweight plus a weight-related condition. (Drug label)
• In trials, people lost more weight than on placebo, and weight loss was also seen in older adults. (Studied in a trial)
