Products in treating erectile dysfunction have been in constant development. Vardenafil is one of the products which is a PDE5 inhibitor and has been sold under the brand name Levitra. Vardenafil functions similarly like viagra or its clinical name, sildenafil, and like cialis or tadalafil. They are similar in their molecular structure in terms of composition except that the nitrogen atom is placed differently making that of sildenafil citrate’s piperazine ring methyl group to an ethyl group. Among the three drugs, it is valdenafil (generic Levitra) that has a relatively average effective time.

Sildenafil citrate has the shortest while tadalafil has the longest effective time. Patients must be aware that medications have their side effects, and Vardenafil is no different. The most common adverse reactions ar the same among the PDE5 inhibitors, which include nausea, abdominal pains although tolerable, back pain, photosensitivity, blurred and abnormal vision. If used incorrectly, which the patient must know to not overdose, is heart attack, although this case is very rare. When vardenafil is mixed with nitrates, the reaction can cause or might provoke the occurrence of hypotension or low blood pressure. As such, patients must then note that when they are taking any nitrate medication, they must not administer vardenafil. It can also damage the penile tissue sometimes, and can result in permanent impotency.

These products are now commonly used to treat impotency or erectile dysfunction in males. Medical statistics show that one in ten males experience erectile dysfunction, so it is quite common. However, this is not usually brought up by men since being impotent has been a taboo for them. It is, in fact, actually the most dreaded problem that all male prays to avoid. Likewise, they are also afraid that they might not provide the best sexual satisfaction to their partners. And men treat potency as a symbol of success and masculinity. Why does impotency occur? Studies have shown that erectile dysfunction ca be credited with various medical, physical and psychological causes.

Among the causes are vascular diseases such as arteriosclerosis that causes a reduction of blood flow in the body, diabetes milletus, high blood pressure and high cholesterol level which can rupture the veins in the penis and reduces their capacity to maintain blood pumped during sexual arousal, drug abuse, hormonal imbalance, neurological conditions, pelvic traumatic experience, prostate-related surgery, radiation therapy, peyronie’s disease, venous leak and various psychological conditions. There are also abuses in the body that can cause traumatic conditions which can ultimately lead to impotency. Smoking is one of them as this can lead to vascular-related diseases. Drug abuse, too can lead to erectile dysfunction. Aside from drugs, alcohol may cause the vascular and the nervous system to work improperly, ultimately affecting potency.
