How does Viagra / Sildenafil Citrate work?
Sildenafil Citrate has a very simple method of working; it stops a
natural enzyme phosphodiesterase in the human body from working.
This places it in a group of medicines known as PDE5 inhibitors.
Phosphodiesterase is also present in the penis of men and when it
exerts its effect, men become unable to sustain their erection.
Sildenafil Citrate stops this phosphodiesterase from becoming fully
active.
Pfizers original aim in developing Sidenafil Citrate was to get FDA approval for it as a treatment for pulmonary arterial hypertension. But once it was discovered that the drug also works well in men with erectile dysfunction, it also got FDA approval as a treatment for this condition.
Since then, Viagra has never been out the news for well over a decade. Its uses, benefits and effects have been written about in news, forums, discussion boards and every other place possible. It was and continues to remain the most popular and widely-used treatment for male impotence. The FAQs that follow provide all necessary information about this medication.
Side Effects of Viagra
Viagra is a highly potent medication that may also have certain side
effects. Depending on the dosage prescribed by your doctor, the
symptoms of Sildenafil Citrate side effects might be strong or mild.
Some side effects experienced by most patients include changes in
vision such as colour tinging, blurring and sensitivity to light;
indigestion; diarrhoea; flushing; headaches; nasal congestion; and
urinary tract infection.
Sildenafil Citrate side effects could turn dangerous if the drug is mixed with alcohol or taken by women during pregnancy. While alternatives of Sildenafil Citrate are generally safe medications, an overdose might lead to heart attack, stroke, sudden changes in blood pressure or sudden death. An overdose can be especially bad for men with known cardiac conditions; such men should always stick to the dose prescribed. Last but not the least, it is a medication for adult men and should not be taken by boys under the age of 18 years.
Guidelines before Taking
The most important guideline for taking Sildenafil Citrate is to
remember that it is not a regular dosage medication; it should only be
taken before sexual activity. Sildenafil Citrate generally requires
30-45 minutes to become effective, so ideally it should be taken about
one hour prior to sexual activity.
