Complete list of ED drugs?

Among the medications prescribed for the treatment of erectile dysfunction, the first line of drugs are the so-called PDE5 inhibitors, which include Viagra, Cialis, Levitra, Staxyn, and Stendra. All of these are oral medications designed to be taken 30 minutes to an hour before sexual activity. They work by temporarily blocking the effects of an enzyme known as phosphodiesterase-5, which tends to impede blood flow to the penis and make it difficult to achieve an erection.

The other main category of prescription ED medications covers the drugs that are directly injected into the penis. Like the PDE5 inhibitors, these drugs are designed to maximize blood flow to the penis. They do so by dilating or widening the blood vessels that supply your penis and generally take effect within 5 to 10 minutes after the injection. Medications in this category include the generic injectables alprostadil, papaverine, and phentolamine and brand name drugs that contain one or more of these generics. Brand name medications include Caverject (alprostadil), Pavabid (papaverine), Bimix (alprostadil and papaverine), and Trimix (alprostadil, papaverine, and phentolamine).
