Vardenafil, known under the brand name Levitra is a prescription medication for male erectile dysfunctiontreatment. It belongs to a class of drugs called PDE5 inhibitors. Levitra increases blood flow to the penis, which helps gain and sustain an erection during sex. Levitra’s active ingredient works on the chain of reactions within the penis during arousal, when the corpus cavernosa (two large chambers) in the male’s penis fills with blood, resulting in an erection.A penile erection happens when the penis fills with blood. This occurs when the blood vessels that supply the penis with blood expand (dilate), and the vessels that take blood away from the penis contract, resulting in an accumulation of blood in the penis.
