New dissolving film for ED shows promise in large trial
NCT ID NCT05490680
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new oral film form of sildenafil (the active ingredient in Viagra) at doses from 25 mg to 100 mg in 488 men with erectile dysfunction (ED). The goal was to see if the film is safe and effective compared to a placebo. Participants took the film as needed before sexual activity, and researchers measured improvements in erection function and sexual encounters.
