Viagra is now not the sole cure to impotence. A number of medications have come up that claim to curb this disease called erectile dysfunction. These drugs belong to the class of PDE-5 inhibitors. The drugs promise effects like increased blood flow to the penis and better penis enlargement. Some even claim to be herbal. All these medicines act in different ways to heighten the sexual pleasure.

Impotence occurs when the male is unable to sustain the erection long enough to enjoy the sexual intercourse. In some cases, it is difficult even to achieve an erection. This condition can be caused due to a physical injury or due to a psychological trauma. The shock affects the nerves and reduces the blood flow in the penis.

Levitra is one of the drugs that help to control this disorder. This FDA approved drug has been tested on thousands of men in about fifty clinical trials. The results were positive and showed that the medicine could treat diabetes and prostrate cancer as well. However, the drug also causes certain side effects. The most common reactions are headache, flushing and a runny nose, but all the reactions are mild and disappear quickly. Some uncommon but dangerous effects can be a prolonged erection that continues for hours together and inability to differentiate between the colors blue and green.

Levitra works in a simple manner. It relaxes the muscles and the blood vessels in the penis, thereby inducing an erection. The drug has to be taken orally once a day. One dosage produces an erection long enough for the patient to have sexual intercourse. An important fact to know about the drug is that it does not stimulate sexual urges, nor does it cause an automatic erection. The patient still needs to have a sexual arousal before achieving an erection. It is also not a permanent cure for impotence. The effect of the drug subsides after the intercourse.

Levitra is said to be better than its predecessor Viagra. Another such drug is Cialis. The effect of this drug is supposed to be strong enough to last for 36 hours at a stretch.

The advent of these drugs has proved to be a boon to the victims of erectile dysfunction. The drugs were such a breakthrough, that they earned their inventors a Noble Prize. A prescription is required to purchase these drugs. Prescriptions can also be filled on websites and the drugs bought through online medical stores. A relevant question here is how long can a person thrive on these drugs. It is advisable to consult physicians for frequent usage of the drugs. One can also go for other surgical treatments like penile injections and vacuum tubes.
