Erectile dysfunction (ED), also known as impotence, is characterized by the inability to develop or maintain an erection necessary for satisfactory sexual intercourse. It is common disorder amongst men that can occur at any age, but generally men above the age of 65 are known to suffer from it. However, this is not necessarily an age related disorder, but more a result of age related health conditions that cause ED; but, it can be treated at all ages. It is primarily caused by health conditions such as multiple sclerosis, diabetes mellitus, kidney diseases, and endocrine gland disorder. Erection may be prevented by problems with the tissues that surround the penis. Psychological factors such as anxiety, stress, and grief also contribute to ED.
Numerous treatments for ED are available on the market. A particular treatment for ED depends on the factors causing it. Treatments for ED ensure that the person suffering from the problem returns to normal sexual activity after taking any of these medications.
Overview of Viagra
Sildenafil citrate, marketed commercially as Viagra, is an FDA approved drug used for the treatment of impotence. It belongs to a group of drugs known as phosphodiesterase 5 (PDE5) inhibitors. It is also called the blue pill. This medication increases the blood flow to the specific areas of the body as well as relaxes the muscles. It prevents PDE5 inhibitors from working too quickly. The penis is one of the areas where PDE5 inhibitors work. Sildenafil controls the inhibition of enzymes and helps in achieving and maintaining an erection, when the penis is physically stimulated. Using sildenafil relaxes the muscles. This drug is available only by prescription. Women and children should not use this medicine. It should be stored away from moisture, direct sunlight and heat.
