Erectile dysfunction includes varied sexual problems, but usually it is regarded to be the constant inability to achieve a satisfying erection. The condition is usually called male impotence although this is not accurate, since impotence includes other signs and symptoms such as lack of sexual desire or difficulty to reach orgasm. Erectile dysfunction may include permanent or total absence of erection. There are many reasons for this sexual condition, and hence there is no general treatment that could improve the condition. For example, older men who experience erectile dysfunction may be caused by physical factors such as injury, old age problems and other related health conditions. The good thing is that regardless of the age, erectile dysfunction can be treated and there are modern drugs that are specifically formulated for this condition. These drugs such as Viagra, Cialis and Levitra all contain Sildenafil.
What is Sildenafil?
Basically, Sildenafil is sold as Viagra and other brand names. It is a prescription drug used for the treatment not only of erectile dysfunction but also pulmonary arterial hypertension. It was originally formulated by UK scientists and then introduced to the market by US pharmaceutical company Pfizer. It primarily works by inhibiting an enzyme in the body that affects the blood flow to the penis. Since its introduction in 1998, Sildenafil has been a major medication for erectile dysfunction. It is important to remember that Sildenafil does not offer permanent treatment to erectile dysfunction. However, it could enhance the condition after taking the drug at least one hour before sexual intercourse. Results show that almost 95% increase in erection has been sustained using Sildenafil. However, the effects could vary from patient to patient.
What are the Adverse Effects of Sildenafil?
Like other prescription drugs, Sildenafil can also lead to certain adverse effects. But most of these side effects are usually mild to moderate and can only last for a few hours. Meanwhile, not every man who takes Sildenafil is likely to feel any of these effects. In fact, Sildenafil is well tolerated for most patients. Even if a patient experience side effects these are only mild so they naturally recede without requiring treatment. Adverse effects of Sildenafil may only happen with higher dosage. Typical minor side effects include headache, flushing, abdominal cramps, nasal congestion and urinary tract infection (UTI). There are reported cases of Sildenafil causing temporary changes in visual perception including difficulty in distinguishing blue and green objects.
It is not recommended to take Sildenafil if you are currently taking other medications, particularly prescription drugs for the treatment of heart ailments, angina and hypertension. Never take contraindicated drugs with Sildenafil and you must consult the treatment to your physician before you buy anything. This is also true if you are taking another medication for other sexual problems such as premature ejaculation. You may not feel side effects in taking these two medications together, buy your doctor must check your condition before taking the drugs. Also bear in mind that Sildenafil is not intended for women and patients under 18 years old.
