Statistics say there’s one out of ten men in the UK who suffers from impotence or erectile dysfunction. The good news is, science has made sure there’s an answer to this problem and that is by taking an effective anti-ED drug such as Levitra. Before one can appreciate the action of impotence treatment, however, it is important to first look into the causes which can be classified as either physical or psychological.
The physical causes of impotence are many and of varied origins, such as impaired blood flow due to atherosclerosis (hardening, clogging and narrowing of arteries.) An erection is directly caused by an onrush of blood in the veins in the penile area, so anything that blocks the flow of blood into and out of the penis can cause ED. Other physical causes include taking certain medications such as diuretics and antilipidemics, medical conditions such as diabetes, prostate cancer and Peyronie’s disease, surgery, smoking and alcohol abuse, low testosterone levels, multiple sclerosis, nerve and artery damage from excessive exercise, injuries and diseases affecting the nervous system.
When no physical causes can be attributed to man’s impotence, psychological factors are usually blamed for the condition. These factors include stress and anxiety, a fear of failure, an unhealthy relationship with the sexual partner and depression. These causes of impotence are psychological, meaning, they all happen as a result of the impotent man’s mental disposition, particularly the way he thinks of himself and the world around him. While physical causes of the condition mostly have something to do with a blockage of normal blood flow into the penile blood vessels, psychological causes have no tangible causes.
Levitra Mechanism of Action
Penile erection begins as smooth muscles in the penis relax, triggering an increase of blood flow to the penile area and causing the organ to erect. Levitra or vardenafil works as a selective inhibitor or cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type 5 (PDE5), which results in smooth muscle relaxation and promotes penile blood flow. When physical or psychological factors impede the natural relaxation of smooth muscles or blood flow in the penis, vardenafil interferes by overcoming these hindrances, resulting in an erection.
Levitra is a drug approved by the Medicines and Healthcare products Regulatory Agency (MHRA). However, as any other drug, there are accompanying contraindications that call for caution by anyone considering it, especially those who are taking other medications or are suffering from certain medical conditions such as heart disease, sickle cell anemia, blood clotting disorders, severe liver disease and hypertension.
While Levitra has been statistically proven to be effective as treatment for impotence or erectile dysfunction, it must only be taken with a doctor’s prescription and supervision. This is to ensure that no adverse side effects occur.
