Tadalista is another medication used to treat erectile dysfunction (ED) in men. It contains the active ingredient Tadalafil, which is also a phosphodiesterase type 5 (PDE5) inhibitor, similar to Vardenafil found in Vilitra. Tadalafil works in a similar way to Vardenafil and other PDE5 inhibitors, helping men with ED achieve and maintain erections by increasing blood flow to the penis.
