New constipation drug tested in young and elderly volunteers
NCT ID NCT01655771
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage study tested a single dose of TD-1211, an experimental drug for constipation, in 47 healthy adults split into younger (18-45) and older (65-85) groups. Researchers measured how the body absorbs and eliminates the drug and checked for side effects. The goal was to see if age affects drug safety and processing, not to test if it works for constipation.
