Vilitra 20 mg tablets contain the active ingredient Vardenafil. This belongs to the group of phosphodiesterases type 5 (PDE-5). Thanks to Vilitra 20 mg, the nucleotide depletion of cGMP, released during s*xual arousal, is prevented. The cGMP nucleotide is responsible for dilating blood vessels near the penis. This allows you to significantly improve blood flow to your arteries and ensure complete erection.
