Zhewitra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Vardenafil as the active ingredient, which is a PDE5 inhibitor similar to Sildenafil (Viagra) and Tadalafil (Cialis). Zhewitra 20 mg helps men with ED achieve and maintain an erection by increasing blood flow to the penis during sexual stimulation. Vardenafil works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which increases the level of cyclic GMP (cGMP) in the penis.
