We are all familiar with generics.  The exact copy of the known chemical formula used in the original medicine is what constitutes the generic form of any medicine.  There are multiple reasons why generics are able to be mass produced at a lower cost.  An important step includes manufacturers of generics having to provide proof that their version is an exact copy of the chemical formula of the original medicine and that when used in healthy individuals, the metabolism remains very similar to the original compound.  This shortened pathway of getting approved from Health Canada or a similar regulatory agency ensures less economic burden to manufacturers and provides the obvious advantage of a significantly lower price, as well as improved accessibility for patients.
