Drug class: Phosphodiesterase type 5 (PDE5) inhibitor

Overview

Udenafil is a prescription medication used to treat erectile dysfunction (ED) in adult men. It works by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually stimulated. Udenafil belongs to a group of medicines called phosphodiesterase type 5 (PDE5) inhibitors, similar to sildenafil (Viagra) and tadalafil (Cialis). This medicine is taken by mouth, usually before anticipated sexual activity. It does not cause an erection without sexual stimulation. Udenafil is not intended for use in women or children. Patients should be aware that udenafil does not cure erectile dysfunction or increase sexual desire, and it should not be used more than once per day.
