Combining two ED medicines vs. one medicine for erectile dysfunction
Treatments studied
Part of Kidney & urinary, Mental health clinical trials.
This study compares two different treatments for erectile dysfunction (ED): taking two lower-dose medicines (tadalafil and sildenafil) together once daily, versus taking a single higher-dose medicine (tadalafil) once daily. The goal is to see which approach works better and is safer for men with ED.
