A longstanding challenge many urologists have faced, has been the treatment of erectile dysfunction (ED). Years ago medications for ED treatment, such as Viagra, came on the market which made it easier for patients suffering from erectile dysfunction to find relief. However, Viagra is one of the most short acting erectile dysfunction treatments and generally lasts approximately 6 to 8 hours. Years later, a medication came to the market by the name of Cialis, which generally lasts between 24 and 36 hours. Levitra, another erectile dysfunction medication, lasts approximately 18 hours. Most patients are surprised when they realize Cialis lasts up to 36 hours, Viagra lasts 6 to 8 hours or Levitra can last 18 hours.
It is a common misconception that patients believe during this period of time they will have an erection the entire time. This is false! Although when the patient takes the medication, it circulates in the body, the patient is generally in the flaccid state. It is during any sexual stimulation or intimacy when an erection can be easily achieved and maintained. It is important to remember to always use your medication under the supervision of your physician and be sure that you are aware of the side effects of the medication before you take it.
The class of drugs that Levitra, Viagra, Stendra, and Cialis belong to are called PDE5 inhibitors. They work by relaxing tight blood vessels, allowing more blood to surge into the penis and cause an erection, says Gregory Bales, M.D., an associate professor of urology at the University of Chicago.
The little pills do the trick for more than two-thirds of men with Viagra protects the heart (ED). They also work for guys who simply need them for a short time to get their “confidence back,” says Michael Eisenberg, M.D., director of male reproductive medicine and surgery at Stanford University.
