Does it really make sense to pay more for a brand drug when there is an alternative in a form of generic? This question is important for lots of people since huge amount of pharmaceuticals at every Canadian pharmacy online can put customers in a real funk. And this is a matter of concern for many men who would like to save on purchasing Viagra, but have some fears about generics effectiveness and safeness. So letâs find out what the difference between brand and generic Canadian Viagra is and what advantages each type of medications has.
Some pharmaceutical companies like Pfizer (which is a legendary manufacturer of Viagra and a developer of sildenafil citrate, its active substance) have their own laboratories for new drugs research and development. On average, such a development costs more than 600 million dollars while preclinical studies and clinical trials take 8-9 years. Thus to bring sildenafil to Canadian pharmacy its developer spent almost 1 billion dollars! With the aim to recompense expenses the company gets a patent for an original drug which entitles it with exclusive right to sell the medicine for a certain amount of time. The patent comprises drug original formula, methods of manufacture and international name and usually is issued for 15-17 years. Then pharmaceutical company firm conducts advertising campaign and gradually creates a new recognizable brand like Viagra in Canada.
But when the patent expires other manufacturers are entitled to produce similar drugs with the same active substance at their own facilities upon the condition that equivalence of these drugs to the original medicine will be confirmed properly. Confirmed analogues are called generics. Generic drugs get new names, they differ from the original in package, color and form, but have the same international non-proprietary name. In case of Viagra this name is Sildenafil Citrate.
Accordingly, buying Canadian sildenafil online you get a well-tried drug based on the same active substance as brand Viagra with proven equivalence.
Types of equivalence:
- therapeutic – pharmacotherapy efficacy and safety of generic is similar to brand drug;
- pharmaceutical – generic drug have to fully repeat pharmaceutical dosage form and composition of the original. Under special circumstances other inactive substances can be used in generics;
- pharmacokinetic or bioequivalence – mechanisms of action have to be similar to brand drug.
So, generics are the same popular brand medicines because they contain the same ingredients and have equal effects. However, the cost of generic drugs can not be compared with the originals and when we speak about cheap Canadian Viagra we always mean generics. Why?
For generics manufactures there is no need to develop new formula of an active substance which is the main component of a drug. And they do not need to spend money and time for aggressive advertising campaigns as well as for creating effective marketing solutions since the drug was already launched on the market. The company spends funds only on production and equivalence tests so there are comparatively low expenses and therefore generics are cheaper. Buying Canadian Viagra online you get an additional chance for saving your money since you can receive ordered medicines directly from a manufacturer without addition to price.
