Pharmaceutical companies investing in R&amp;D deserve to make a return on their investments. Research and development can take a long time and will cost significant sums of money. The cost of creating many new drugs was estimated to be as high as $5 billion in 2013 [1] . There is also a risk that the drug may fail during the various phases of production, which makes the $5 billion price-tag even more daunting.
