Zenegra Vs. Viagra

Sildenafil, the common denominator in Viagra and Zenegra

The drugs are defined as generic or equivalent when, compared to the medicinal product or "brand medicine", they have the same active ingredient, the same pharmaceutical form, the same dosage and the same route of administration. Generic drugs are drugs in all respects and can be marketed when the branded medicinal product is no longer covered by a patent. The equivalent drug may have the name of the active ingredient followed by that of the manufacturer or a fancy name.

The company that "discovers" a new active ingredient patents it, creating a medicinal specialty with a fancy name. Another pharmaceutical specialty containing the patented active principle cannot be marketed without the permission of the patent holder.

Viagra, or rather its active substance sildenadil, was discovered in the early 90s and got patented by the American company Pfizer, not without certain initial crediting litigations though. Legally, the copyright and exclusive manufacturing rights have been the prerogative of Pfizer for the better part of 20 years that sildenafil has been around. But as of the second decade of our century, the patent for monopolistic production of Viagra started expiring in one country after another. In the U.S., the generic version of the legendary blue pills will not be available for another year, but it is possible to order cheap generic sildenafil from other countries, where their production is totally legal.

Zenegra is one of such generically produced Viagra equivalents having sildenafil citrate as its active component. When the patent coverage expires, any other company, having obtained the authorization from the competent authority, can market the equivalent drug. In the U.S., patent coverage is much longer than in other countries and can last up to 38 years compared to the 20 years set by the European Union. As a result, the placing on the market of equivalents is delayed compared to other countries where patent coverage has a shorter duration.

What then is the difference between the brand name Viagra and the equivalent drug Zenegra?

From a pharmacological point of view, there is no difference between the brand Viagra efficacy and that the drug equivalent Zenegra (in the pharmaceutical science, this is called bioequivalence).

From the economic point of view there is a price difference that can be substantial: generic sildenafil (Zenegra) is cheaper than the brand drug, according to the laws, it must cost at least 20% less at the time of registration – but Zenegra will help you save up to 90% of the brand Viagra cost, depending on the vendor. What we are talking here is the bare cost of production, which is much less for Zenegra as it is manufactured in India, where the workforce is considerably less expensive.

Also, Zenegra being a generic, it only comprises the cost of materials, workforce and a very small profit markup. By contrast, Viagra cost also includes the investments made by the developing company more than 20 years ago. One can argue that these investments have been won back many times over during the decades of outrageously successful Viagra marketing, and it is a very good point. However, the way the industry works, this logic does not apply to profit-making.

The equivalent drug must no longer amortize the research costs (which have already been amortized during the patent coverage period). To market it there are no promotional costs because the molecule has already been widely known for years.

Therefore the price of an equivalent can be much lower than the price the brand specialty had, when the active ingredient was still covered by a patent.

Often, in order not to lose market share, producers tend to align the price of the branded drug with that of the equivalent medicine – Pfizer manufactures generic Viagra overseas, too. This is not such a new scene in the industry: in a short time, due to competition, the price of a well-known branded anti-inflammatory was reduced by 50% when, after the patent had expired, other companies produced the same medicine at a lower price.

The difference between Zenegra and Viagra

The choice involves doctor, pharmacist and patient. The information provided by the pharmacist on the existence of the equivalent drug – whether the drug is provided by the healthcare authorities, or whether it is a paid medicine – allows the citizen to choose the most economical cure. The take-away message is that patients are safe using either of the drug versions, with the health outcomes being completely mutually interchangeable.

Zenegra is one of the generics whose pharmacodynamic and pharmacokinetic characteristics fully coincide with those of the brand drug. Zenegra is available in exactly same doses as Viagra, which is its major benefit – not all of the Viagra generics come available in the same dosages, which curtails the therapeutic adjustability of the active substance. The actual difference lies in the price, which is displayed in the table below.
