Generic Viagra Vs. Branded Viagra

Viagra is a branded medicine available in the form of pill, which is used to treat male impotence. It works by facilitating tension in blood vessels and improving blood flow to the penis. This helps men to achieve and maintain an erection required for sexual intercourse.
There are following differences between branded Viagra and its generic versions namely Penegra, Zenegra, Suhagra, Silagra, Kamagra, Edegra, Caverta etc.
• Name
• Appearance and form
• Manufacturer
• Price
• Efficacy and side effects
• How to purchase
Out of all of the above only name, cost and appearance are having some differences; but in other factors, such as activity of function and medicinal content, there are virtually no differences. From the time when becoming available in 1998, Viagra has become hot-selling drugs in history and manufactured by Pfizer. Above 23 million men globally have used the drug.
Actually, the 15-year patent on Viagra ran out in 2013, and since then it became available for generic reproduction by different names.
Over the past two decades, there have been numerous counterfeit forms of the drug which are available with online pharmacy stores; however, since 2013, Sildenafil Citrate has become a legitimate and legal treatment option for male impotence.
To clear up any confusion, we thought we would highlight the main differences between Viagra, the branded version of the drug and its generic counterpart. Let us discuss how both the versions came into existence-
When Pfizer first developed the Viagra for the treatment of ED, they issued it under a marketing-friendly brand name like makers of other types of products.
Usually, when the patent license on any drug runs out, after a period of 15-20 years, the MHRA – (Medicine and Healthcare products Regulatory Agency) will grant other manufacturers permission to produce the exactly same medication.
But these companies will not be able to sell it under the original brand-name. Alternatively, they will sell it under the active ingredient’s name of the drug, which is Sildenafil in this case.
Appearance and Form
Pfizer also continued the trademark on the look of the drug that is the blue diamond shape, in addition to also keeping the same name “Viagra”. Successively, other manufacturers of Sildenafil were not able to manufacture the drug with a similar appearance. Sildenafil cittrate tablets will simply be issued as a regular-shaped white or blue tablet. In 2012, a chewable version of sildenafil citrate  i.e. Nipatra, was released by Mercury Pharma.
The other common difference is that, the Viagra tablets have ‘VGR’ and the dosage amount inscribed on them, Sildenafil normally has ‘SL’, followed by the dosage inscribed.
An important point to note is that the producers of Viagra will always be Pfizer unless they decide to merge or sell the brand or acquired by another firm. On the other hand, sildenafil is open to wider imitation, and it can be made by any pharmacy company provided that they obey to the same preparation procedure and manufacturing conditions to make it as that of the original.
