How does Danuglipron work?
What it does in the body, and where.Danuglipron was an attempt at an oral GLP-1 pill using a small molecule rather than a peptide. Development stopped.
- 01It activated the GLP-1 receptor as a small moleculeThe same approach that orforglipron went on to succeed with.
- 02Development was halted in April 2025Pfizer stopped the program after a participant showed signs of drug-induced liver injury, which resolved when the drug was withdrawn.
- 03It is here for reference, not as an optionThe dose figures on this page are historical. This is not something you can obtain or should be seeking.

What else is it used for?
Each use below carries its own evidence level. Approved means regulators have cleared it for that purpose. Investigational means it is in trials. Early research means it is being studied and is not established.
- Weight loss without injections. Development was discontinued in 2025, so nothing is approved or availableResearch only
