No man wants his sex life to be dull or disappointing to either him or his partner. Unfortunately, there are some unforeseeable circumstances that change a man and his sex life. One of these circumstances is erectile dysfunction; a condition that no man anywhere wants to ever have. There are many reasons why a man can get erectile dysfunction. Most cases of erectile dysfunction result from a number of organic reasons. Erectile dysfunction in these cases is caused by various different physiological issues. In the vast majority of erectile dysfunction cases in men aged above 50 years old, organic reasons are the main cause of the condition.
The most common of erectile dysfunction causes is the atherosclerosis of the penile artery. This disease causes the walls of the walls of said artery to solidify when fats, cholesterol and various other cell flotsam and jetsam develop in them after some time. This procedure normally happens ubiquitously all through the body. A patient with coronary artery disease is at a greater position of contracting erectile dysfunction than one without the disease.
There are other causes of erectile dysfunction, including several psychological issues.
Erectile dysfunction is perhaps one of the worst things that can afflict a man, hence he would want to rectify the issue as quickly as possible.
There are a number of different drugs that are used to treat erectile dysfunction. One such drug, which has been marketed under a variety of names (such as Silagra), is sildenafil. Sildenafil is used to treat erectile dysfunction as well as pulmonary arterial hypertension.
Sildenafil works by securing the cyclic guanosine monophosphate (cGMP) from debasement by cGMP-specific phosphodiesterase sort 5 (PDE5) in the corpus cavernosum. Nitric oxide in the corpus cavernosum of the penis ties to guanylate cyclase receptors, which brings about expanded levels of cGMP, prompting smooth muscle unwinding (vasodilation) of the intimal pads of the helicine conduits. This smooth muscle unwinding prompts vasodilation and expanded inflow of blood into the elastic tissue of the penis, bringing on an erection.
As with all other medication, there are a number of side effects related to Silagra. These side effects are basically typical of all other sildenafil products. In some trials of sildenafil, the most commonly occuring adverse effects of the use of Silagra are flushing, headaches, indigestion, impaired vision, photophobia, blurred vision and nasal congestion. Some Silagra users have complained of cyanopsia (a blue tint in one’s vision). Some other side effects include blurriness and also loss of peripheral vision.
It is very possible for Silagra (or sildenafil products in general) to lead to vision impairment in rare cases. The use of Silagra has also been linked with nonarteritic anterior ischemic optic neuropathy. Other serious side effects, though rare, found through a number of studies, include seriously low blood pressure, prolonged erections, myocardial infarction, stroke, ventricular arrhythmias, increased intraocular pressure, and sudden loss of hearing. In October 2007, the United States Food and Drug Administration announced that the labelling for Silagra (and all sildenafil products) as well as all PDE5 blockers were in need of a more prominent warning of the potential risk of sudden loss of hearing.
