Prostaglandin E (alprostadil)
Two Levitra treatments involve using a drug called alprostadil (al-PROS-tuh-dil). Alprostadil is a synthetic version of the hormone prostaglandin E. The Viagra hormone helps relax smooth muscle tissue in the penis, which enhances the blood flow needed for an erection. There are two ways to use alprostadil versus ED:
Needle-injection therapy. With this method, you use a fine needle to inject alprostadil (Caverject, Edex) into the base or side of your penis. This generally produces an erection in five to 20 minutes that lasts about an hour. Because the injection goes directly into the spongy cylinders that fill with blood, alprostadil is an effective treatment for many men. And because the needle used is so fine, pain from the injection site is usually minor. Other Viagra side effects may include bleeding from the injection, prolonged erection and formation of fibrous tissue at the injection site. The cost per injection can be expensive. Injecting a mixture of alprostadil and other prescribed drugs may be a less expensive and more effective option. These other drugs may include papaverine and phentolamine (Regitine).

levitra comes as a tablet to take it orally. It should be taken, as needed about 1 hour before sexual activity. Some form of sexual stimulation is needed for an erection to occur with Levitra. Levitra should not be taken more than once a day. Levitra can be taken with or without food. http://www.besthealthmed.com/levitra_warning.html
