Viagra is an effective and safe oral drug used to treat erectile dysfunction (ED). The medicine works meticulously by helping men previously suffering from ED, to attain and maintain an erection for a sexual intercourse. Sildenafil Citrate is the first oral compound used to treat erectile dysfunction. It has been working for over 10 years now.

Mechanism of Viagra

How an erection is formed?

A normal erection is achieved once a substance called nitric oxide (NO) is released. NO will heighten an enzyme called “Guanylate Cyclase”. This enzyme will boost the volume of cGMP (Guanosine Monophosphate), which is responsible for relaxing the muscles in the corpus cavernosum (muscle of the penis). This process allows more blood to flow in to arteries of the penis and ultimately an erection is formed.

However, this process is affected by different factors. The factors causing a poor erection can be depression or injuries amidst others.  These determinants will either affect the level of nitric oxide released or limit the relaxation process of the muscle as PDE-5 is not inhibited.

When to consume Viagra

Viagra should be consumed 30 to 60 minutes before a sexual intercourse. This will give the sildenafil citrate sufficient time to become effective within the human body. If Viagra is consumed only 10 minutes before a sexual interaction it does not necessary function well but it can, depending on the body’s absorption rate. The drug will remain effective for up to 4 hours in the patient’s body.

Physiologic mechanism of how a man achieves a better erection with the help of Viagra?

Viagra (Sildenafil Citrate) does not relax the muscle of the penis but it boosts the capacity of Nitric Oxide (NO). This is done by restraining (inhibiting) the PDE – 5. Phosphodiesterase type 5 (PDE-5) is an enzyme which is released to allow blood to exit the arteries of the penis and this will revert the penis back to its normal flaccid state. The phosphodiesterase type 5 (PDE-5) can thus be said to be directly responsible for the degradation of an erection as it affects the level of cGMP in the penis and is ultimately responsible for erectile dysfunctions.

How Viagra Helps?

A sexual stimulation making a man aroused will automatically lead to the release of nitric oxide. This discharge of nitric oxide will initiate an erection and as the PDE – 5 is restrained by Viagra (Sildenafil) the level of cGMP will increase in the corpus cavernosum. The muscle in the penis will remain relaxed and blood will flow into the penis. A man will thus be capable of forming an erection and maintain it as Viagra is inhibiting the PDE–5 enzyme.

What Viagra cannot do

Viagra is effective in treating erectile dysfunction but it CANNOT CURE ED. It is simply a treatment and not a cure. Furthermore, there are some who think that Viagra acts as a protection against sexually transmitted diseases but this is not the case. It is simply used to increase the capability to perform sex. The drug is also neither an aphrodisiac nor a hormone.

Summary

Viagra works by enhancing the release of nitric oxide and by inhibiting PDE-5. These are the predetermining needs for a proper erection. Sildenafil Citrate does alleviate erectile dysfunction and treats it. Viagra is working for millions of men.
