Erectile dysfunction can be caused by organic causes like certain vascular disease, endocrine imbalance or neurological disorders. Erectile dysfunction occurs after damaging the parts responsible for erection, especially the nerves, blood vessels and corpus cavernous of the penis. Of these, the most common diseases that can cause erectile dysfunction are: diabetes, atherosclerosis, arthritis, adrenal insufficiency, La Peyronie’s disease, alcoholism, smoking or abuse of illegal drugs. Organic causes may also be some surgery that results in the interruption of pelvic nerve plexus, such as ablation of the prostate, bladder or rectum. And certain drugs can cause erectile dysfunction, such as those indicated in the treatment of blood pressure or antidepressants.
The treatment for erection problems depends on the cause that leads to this problem; it may be psychological, physical or a combination of both. Erection problems that have one or more major physical causes, and also psychological reasons cause a more severe type of erectile dysfunction and therefore, the treatment is more complicated.
Many doctors use a wise approach in treating erection problems, using the least invasive treatments first. Many times, especially in old patients, erectile dysfunction can be a side effect of medication. In some cases, the elimination of drugs that can cause this problem restores the sexual function. Only a medical specialist can change the medication, it is not safe to try a different medication without medical consent.
Oral medication (such as Viagra, Levitra or Cialis) is the most common treatment for this problem. Viagra was the first oral medication for erectile dysfunction approved by the U.S. Food and Drug Administration. Chemically they are phosphodiesterase-5 inhibitors (PDE-5) that increase the level of nitric oxide- a substance that relaxes the penile muscles allowing an increase amount of blood flow.
A good blood circulation is essential to a normal erection; any disturbance in blood flow eventually leads to erectile dysfunction. Also in order to have an erection physical and psychological stimulation is necessary. In general these medications produce an erection within 30 minutes after ingestion. Medications prescribed for the treatment of erectile dysfunction may interfere with other drugs and have side effects such as headache, flushing, indigestion, muscle pain. There are situations in which these drugs have led to adverse events, such as scars or persistent erection (priapism).
Also they drop blood pressure, so are not recommended for those suffering from hearth diseases.
Over the counter drugs are the natural alternatives to medications prescribed in the treatment of erectile dysfunction. Their effect is the same-increase the level of nitric oxide and relaxes the smooth penile muscles. They are made of natural ingredients and are safe to use.
