Zhewitra 20 mg is a medication that contains vardenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor. Like other medications in this class, such as Viagra and Cialis, vardenafil is primarily used to treat erectile dysfunction (ED) in men. When a man is sexually stimulated, vardenafil helps to increase blood flow to the penis, allowing for an erection to occur and be maintained. It's important to note that vardenafil will only work if there is sexual stimulation present.
