Question 413 of 433
What is the next wave of weight-loss medicine?
The short answer
Pills, monthly injections, stronger combinations, and, eventually, lower prices.
Pills: an oral form of semaglutide was approved for weight loss in December 2025, and orforglipron followed in April 2026.
Stronger injections: retatrutide produced average weight loss of up to about 28 percent in late-stage trials, with an application planned for early 2027. A combination called CagriSema is under FDA review.
Less frequent dosing: an injection given monthly or even less often is in Phase 3, with results expected in 2027.
Price: generic semaglutide went on sale in 2026 in India and Canada and has been approved in Brazil and other countries. In the United States, no generic is expected before the next decade.
The open scientific questions are the ones that matter for longevity: how to keep muscle while losing fat, and what happens after ten or twenty years of use.
