Viagra is perhaps the most familiar name when it comes to the treatment of erectile dysfunction or impotence. There is no other medication that has revolutionised this field of medical science with the same impact as that of Viagra. This medication, in scientific terms, is referred to as sildenafil citrate and was introduced by Pfizer Limited in the market for the first time in 1998. The history of treating erectile dysfunction will tell you that before the invention of Viagra there was no such medically-approved medication that could address this problem accordingly. Thus, prior to the late 90s, natural herbs and vasodilator injections were the only options for people. It is not difficult to understand the huge popularity of Viagra and its integral association within popular culture. The diamond shaped blue-pill gave hope to people throughout the globe to treat their erectile problems. Compared to the other forms of treatment, Viagra was authentic and clinically proven to help sustain an erection for a considerable time period. The medication enjoyed so much commercial success that many other companies created illegal generic varieties under the term “generic Viagra”.

How does Viagra work?

To understand the functional mechanism of Viagra you must get a clear idea about the erectile mechanism. It is quite a complicated process and occurs in a step-by-step manner. First, you must be sexually stimulated and signals of the stimulation will be accepted in your brain. In the next stage, stimulations generated by the brain will be delivered to your penile region through the central nervous system. In the third stage, depending on the strength of sexual stimulation, cGMP secretion starts, which plays the most effective role in relaxing penile blood vessels so that increased blood flow occurs. Blood flow creates pressure that hardens the muscles of your penis and causes an erection. Finally, secretion of PDE-5 deconstructs the cGMP cycle and the process ends.

Every Viagra blue-pill contains sildenafil, one of the strongest PDE-5 inhibitors, and it also plays a major role in encouraging extra blood flow within the penis. On one hand the inhibiting capacity of PDE-5 stops the enzyme from breaking down the cGMP cycle. On the other hand, this chemical allows sufficient blood flow within the penis. Due to the combined effect of these two drugs you not only get an erection but also receive the capacity to sustain it for an adequate time period. However, we would like to inform you that you must take special precautions if you use generic Viagra pills for treating your erectile problems. In several cases it has been reported that the generic Viagra pills contain higher dosages of sildenafil than the medically approved limit.

The right dosage of Viagra would work the best for you

What dosage of Viagra should be taken? Viagra pills are available in the market in three different strengths, namely, 25mg, 50mg, and 100mg. Depending on your physical condition and nature of the erectile problem, your doctor will prescribe you with the right dosage. Always remember that no matter which dose you are prescribed with you must not take more than a single pill of the drug in a day. You may face the risk of sildenafil overdose if you don’t maintain a gap of 24 hours between two dosages. Generally Viagra users don’t face any serious complications if they follow the prescribed dosages but your negligence while using this medication can be dangerous if you don’t follow the right method.
