New Weight-Loss Drug's effect on other medications tested in healthy volunteers

This completed Phase 1 study looked at how orforglipron, an experimental drug, changes the way the body processes several common medications (digoxin, simvastatin, rosuvastatin, acetaminophen, and midazolam) in 50 healthy overweight or obese adults. The goal was to measure drug levels in the blood, not to treat any disease. Participants took each medication alone and then with orforglipron to see if there were differences. The study provides important safety information for future use of orforglipron.
