After reading a wide array of medical research, it is not hard to believe that there are many physical disorders which have no known cause. But as simple as previous line is to understand, it presents us with next challenge, how do you treat a disorder which has no known causing factor. Such diseases are autoimmune diseases, cancer, genetic diseases and other congenital physical deformities. Since no specific cause or trigger is known, one has to live with such disorders.

There are many disorders which are gender based. Such gender specific disorders are usually affiliated to abnormal functionality in genetalia or any other part directly affiliated to it. One gender specific disorder which is commonly faced by many men around the globe is erectile dysfunction. This is a disorder in which a male fails to retain the erection to complete the sexual process. This results in bad sex life of a couple and leads to low self esteem and confidence, and in many cases it leads to divorce and even suicide by the male partner. Therefore treating such disorder is of high importance to maintain a standard social structure.

Due to a demand from significant amount of people from all around the world, there are many drugs out there that help a man to overcome this dysfunction and hence to overcome its consequences.

PDE5-inhibitorGeneric Vardenafil is one of the famous drugs which are used by men facing erectile dysfunction. Chemically Vardenafil belongs to the same family as Sildenafil. Sildenafil is the pharmaceutical name of another famous drug called Viagra. There are a lot of similarities in the chemical structure of Vardenafil and Sildenafil hence the similarity in their actions. Overall Vardenafil has a short effective time duration but when compared to Sildenafil, it has faster effects which remain for longer duration of time.

Vardenafil and Sildenafil are PDE5 inhibitor. PDE5 inhibitors are the drugs used to stop the action of phosphodiesterase type 5 on cyclic GMP. This chemical compound is present in the smooth muscle cells lining the blood vessels supplying the corpus cavernosum (erectile tissue) of the penis. GMP is an important chemical that regulates blood flow in penis and in lungs. Once it is inhibited, there is higher blood flow into the penis which results in erection. PDE5 is also present in the arterial wall of smooth muscle within the lungs; therefore PDE5 inhibitors have also been explored for the treatment of pulmonary hypertension. This is a disease in which blood vessels in the lungs become abnormally narrow resulting in lesser oxygenation of the blood for rest of the body.

PDE5 inhibitors have many side effects if consumed in a larger amount than prescribed. One may feel the side effects like nausea, abdominal pain, back pain, photosensitivity, abnormal vision as many users notice a blue colored tint added to their vision, eye pain, facial edema, hypotension, palpitation, tachycardia, arthralgia, myalgia, rash and itch. Another possibly serious, but rare, side effect with Vardenafil is heart attack. Also in rare cases, Vardenafil use may cause priapism which is a very painful condition resulting due to prolonged erection; this condition can cause impotence if left untreated. Vardenafil HCl generic, just like all PDE5 inhibitors, should not be used by men taking nitrate medications, because combining them with Vardenafil might provoke potentially life-threatening hypotension which may not be treated in time to save a person's life. New research shows that people may also experience hearing loss after the intake of this drug.

Vardenafil is prescribed in Vardenafil Hcl tablet form of different amounts, but some of these amounts are not available in different parts of the world so sometimes a patient has to opt for a little higher or a little lower dosage incase it is required. It is available in 2.5 mg, 5 mg, 10 mg, and 20 mg doses in round orange tablets, but in many areas with lower access to the drugs only Vardenafil HCl 20mg and Vardinafil HCl 10mg can be found. This drug should be taken 1 to 2 hours prior to sexual activity. Most men can get the desired effects with 10 mg tablet. It is strictly advised that this drug should not be taken more than once a day. These tablets are available under the brand name 'Levitra Vardenafil HCl'.

Like Viagra, Levitra is very well known in communities and is prescribed very often at hospitals. Many people have used this drug and given positive reviews. There have only been 1% of people who did not respond the same way to the medicine as expected but instead had to deal with a lot of side effects. Either they did not get a proper erection, or rarely if they did, the people could not ejaculate. Other than this few percentage, people are very satisfied with this drug.

Whenever the functionality of Levitra is discussed, it is compulsory to compare it to one of the famous names used to overcome erectile dysfunction, and that is Viagra. Many men, who were not affected or were partially satisfied with Viagra, got a complete erection after using Levitra. Many have even mentioned the fact that this drug affects within next 5 to 15 minutes and has a long lasting effect compared to Viagra. This effect has been proven in clinical trials as well, that Levitra is fast acting and has a long lasting effect as compared to Viagra.

By now this drug might look like an ideal piece and you must be planning to opt for it but wait … after reading many reviews, it is also inferred that even though this product confirms its required actions, it also makes sure to deliver its side effects. About 87% of people who took the prescribed pill, experienced the side effects as mentioned earlier; out of which, many mentioned headaches. This does not stop here; many also mentioned that their vision was affected for some time or they felt congestion, but these all people ended by saying that the pain was bearable and it was worth it. Whereas, out of the people who used Viagra, only 5% of users felt any side effects at all, and out of this minority, very little experienced even half serious effects since majority mentioned that the side effects were mild.
