Viagra is the most well-known therapy for erectile dysfunction or ED. When it was approved by the FDA in 1998, it became the first safe oral treatment for erection problems. It completely changed the way this condition is treated today and remains a sought-after choice. It enhances levels of nitric oxide in the body and this natural chemical works with other enzymes to relax and expand blood vessels. Consequently, blood flow improves leading to better erectile function.

When ED happens it can have a devastating effect on a man’s self-esteem and relationship with his sexual partner. On a positive note, men with this common sexual health issue can now order medication from the comfort of their own home. Since the patent for Viagra expired, the sildenafil price has reduced substantially. The less expensive, unbranded version, sildenafil, is now available online. It is required to be bioequivalent to Viagra so it has the same sildenafil citrate side effects.

The unexpected discovery of sildenafil

The discovery that this medication could lead to strengthened erections was unplanned. In fact, it was originally intended to be used for the treatment of cardiovascular conditions like pulmonary arterial hypertension. A clinical study that examined multiple doses in 38 healthy men took place in the early nineties. The men were given 25, 50 or 75mg sildenafil to take three times a day. An increased tendency to experience erections was reported by:

• 3 of the 9 men who received 50mg
• 5 of the 8 men who received 75mg

This suggested that, although not ideally suited for the treatment of cardiovascular conditions, sildenafil may be an excellent as-needed treatment for ED. This discovery created a better understanding of the scientific working behind ED and its role in men’s sexual health. By improving blood flow to the penis, this medication allows a man with ED to achieve a firm erection in response to sexual stimulation.

The expiration of the patent for Viagra

The fifteen-year patent for Viagra in the UK and parts of Europe reached its expiration date on 21 June 2013. When this happened, other pharmaceutical companies became licensed to reproduce this medication in a generic form. It is simply known as sildenafil as it is named after the active ingredient in Viagra, sildenafil citrate. It contains the exact same medicinal content as the branded version so it works the same way in the body. However, there are 3 main differences:

• Appearance – the original producer of this medication continues to hold the trademark on the appearance of Viagra. Therefore, when it comes to shape and color, generic sildenafil looks slightly different and cannot have the same blue-diamond appearance.
   
• Name – the original manufacturer also continues to hold sole ownership of the name, Viagra. For this reason, generic producers are unable to call their products the same name. This is why several versions of the same medication are available.
   
• Price – generic sildenafil is cheaper than its branded counterpart because generic manufacturers did not incur substantial costs to invent the medication. Also, competition among generic companies results in further reductions in the price.

How sildenafil should be used

Studies have shown that about 82% of men respond well to a 100mg dose. The majority of patients are able to attain an erection that is suitable for sex until successful completion. This medication stays effective in the body for approximately 4 to 6 hours. During this time frame, the user is able to achieve a rigid erection if sexual stimulation happens. If there is no stimulation, there will be no erection.

Sildenafil is highly effective at treating erection difficulties that are the result of physical and emotional issues, or a combination of both. It reaches its highest concentrations in the body within one hour of administration. Since it was launched in the late nineties, this medication has successfully treated more patients with ED than any other treatment option. This fact alone is often enough encouragement for men with ED to try sildenafil.
