Levitra (vardenafil) relaxes muscles found in the walls of blood vessels and increases blood flow to particular areas of the body. It is used to treat erectile dysfunction (impotence). During a penile erection, the penis fills with blood. The blood vessels that supply the penis with blood expand, or dilate, and the vessels that take blood away from the penis contract. The two large chambers in the penis, known as the corpus cavernosa, fill with blood. As the blood accumulates in the penis, an erection result. Vardenafil belongs to a class of drugs called phosphodiesterase type-5 (PDE5) inhibitors. A PDE5 inhibitor stops PDE5 from constricting the arteries. By relaxing the arteries, vardenafil enhances blood flow when a man is sexually aroused. The active ingredient works on the chain of reactions within the penis during arousal. When a male is sexually aroused, nitric oxide is released into his penis, and this triggers a chain of reactions. This causes an enzyme, guanylate cyclase, to produce cyclic guanosine monophosphate (cGMP). cGMP regulates the contraction and dilation, or expansion, of blood vessels that carry blood to and from the penis. The chemical reaction causes the vessels that supply the penis to dilate, while those removing blood from the penis contract. Phosphodiesterase-5 (PDE5), another enzyme breaks down or destroys cGMP. When cGMP is destroyed, the blood vessels return to their normal size, effectively ending the erection. Vardenafil stops PDE5 from destroying cGMP. In this way, it allows cGMP to work for longer. As a result, it helps prolong an erection.
BEFORE TAKING THE MEDICATION
You should not use Levitra (Vardenafil) if you are allergic to Levitra (Vardenafil), or if you take other medicines to treat pulmonary arterial hypertension, such as riociguat (Adempas). Levitra is not approved for men younger than 18 years old. Do not take Levitra (Vardenafil) if you are also using a nitrate drug for chest pain or heart problems. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate. Nitrates are also found in some recreational drugs such as amyl nitrate or nitrite (“poppers”). Taking Levitra with a nitrate medicine can cause a sudden and serious decrease in blood pressure. Tell your doctor if you have ever had: heart disease, heart rhythm problems; a heart attack, stroke, or congestive heart failure; long QT syndrome (in you or a family member); high or low blood pressure; seizures; liver disease, kidney disease (or if you are on dialysis); a blood cell disorder such as sickle cell anemia, multiple myeloma, or leukemia; a bleeding disorder such as hemophilia; a stomach ulcer; hearing or vision problems, vision loss; an eye disorder such as retinitis pigmentosa (an inherited condition of the eye); a physical deformity of the penis (such as Peyronie’s disease); or if you have been told you should not have sexual intercourse for health reasons. Levitra can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoked or were over 50 years old. It is not clear whether vardenafil is the actual cause of vision loss.
