Zhewitra 20 mg is a medication used to treat erectile dysfunction (ED) in men. It contains Vardenafil as its active ingredient, which works similarly to other ED treatments like sildenafil (Viagra) and tadalafil (Cialis), by increasing blood flow to the penis, helping men achieve and maintain an erection when sexually aroused. Zhewitra 20 mg belongs to a class of drugs called PDE-5 inhibitors. It works by blocking the enzyme phosphodiesterase type 5 (PDE5), which is responsible for reducing blood flow to the penis.
