Zhewitra is a medication primarily used for the treatment of erectile dysfunction (ED). It contains vardenafil as its active ingredient, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Like other PDE5 inhibitors such as sildenafil (Viagra) and tadalafil (Cialis), vardenafil works by increasing blood flow to the penis during sexual stimulation, thus helping men achieve and maintain an erection.
