    Which drug is best may depend on your preference for quick onset versus long duration and your individual medical needs. They all work the same way, producing an erection by increasing blood flow to the penis. The Food and Drug Administration has approved four similar drugs for erectile dysfunction, sold under such names as Viagra (sildenafil), Cialis (tadalafil), Levitra (vardenafil) and Stendra (avanafil). The discovery of Viagra is one of the classic stories of serendipity in drug development. In the 1980s, the pharmaceutical company Pfizer began studying sildenafil, the generic name for Viagra, as a treatment for heart disease. It didn’t work, but the men in the study developed unusually strong, long-lasting erections. All four of the currently approved drugs seem to be equally good at producing erections. But it is difficult to be more definitive in evaluatingtheir efficacy, because few studies directly comparing them have been conducted, a common problem with many drugs. The most common sexual dysfunctions in men include lack of interest, premature ejaculation and erectile dysfunction. The latter affects 52% of men between the ages of 40 and 70, including mild, moderate and complete forms of ED. Organic or physical causes for sexual dysfunction in men include vascular, hormonal and neurologic factors. Concerning vascular causes, the risk factors for atherosclerosis (including smoking, high blood pressure, diabetes (diabetics do not respond well to pills like sildenafil (Viagra)) and high cholesterol are ALSO risk factors for erectile dysfunction. Since a straddle injury or use of a narrow saddle can obstruct and impair arteries to the penis, bicycle riding is also considered a risk factor for erectile dysfunction. Little attention has been paid to endocrine factors. Testosterone modulates desire, arousal and orgasmic function.

Content Header .feed_item_answer_user.js-wf-loaded . Medications such as Viagra (sildenafil), Cialis (tadalafil), Stendra (avanafil) and Levitra (vardenafil) are commonly used for the treatment of erectile dysfunction in men. In some ways, these medications are like Pepsi and Coke, very similar but each has its own fans. The goal of using medications such as Viagra and Cialis is to allow men to (1) get an erection, (2) maintain a hard erection. All oral pill medications for ED (Viagra, Cialis, Stendra), called PDE-5 (phosphodiesterase) inhibitors, work through the same mechanism, by prolonging the effect of nitric oxide molecule in the walls of blood vessels of the penis. Nitric oxide presence leads to increased blood flow to the penis. The discovery of the role of nitric oxide on the walls of blood vessels was recognized with a Nobel Prize in 1998 as one of the most important discoveries in medicine. Major differences between these medications are attributable to the speed and duration of their action.
