Of the world is worth about 200 billion so thats just

of the world is worth about $200 billion. So that's Just to give you some idea of the names of
the companies that are involved. And this is a graph or a chart from. Nearly 20 years old, but it

doesn't change very much, these are the sales and billions but percent of global sales is what
i'm interested in. North America has about half of the global sales of medications in
prescription drugs compared with Latin America at 4%, of course, the population is
different. This is what i'd like you to take note of it's about half in the graph now it's about a
billion dollars, instead of 466 billion which it was 18 years ago and it's going to go up even
more, namely a trillion dollars thousand billion. And this this distribution of drug sales
amongst major national markets it's still half in North America. which you if you combine
Canada, the US us is 49% adds about four more percent from Canada. So just taking this into
account that's that's the same in 2007 it's the same today it's still half. And now i'd like to
present you with a. Little. helpful, I think. notion to get into what you can make some
predictions yourself if produce if prediction sales were going up at 10% a year which some
pharmaceutical companies have. That means that sales will double in about seven years and the
way you can get it at that particular information is take the number 70 it's an arbitrary number
that happens to work. divide it by the percent increase per year to give the number of years, it
will take to double so if it's going up at 10% of your. 10 into 17 seven years it will take to
double if it's 35% a year it'll only take about two years to double or to have if it's going down
at 10% a year. So let's say prescription sales are going up by 1.3% divide 1.3% into 70 you get
about 50. Years that sales will take 50 years to double that only 1.3% of years, so if you're
earning 1.3% in the bank it'll take 50 years for your bank account and double that's really what
this is saying it's just a useful mnemonic to get at quick. detail of how much it costs and how
much it takes to double and so forth, so assume that drug. Sales of a drug or decreasing at 10%
a year what's the expected total revenue in seven years with the President revenue is a million
per year. Well, that would be. Half. : So it works both going up and going increasing a 10% or
any other percent a year or decreasing it 10% or any other percent a year divided into 70 and
will be give you revenue will be 5500 million roughly. 500,000 roughly if it was a million per
year. Another topic that needs a bit of comment. It is how the drugs are catalogued I don't think
you need to worry a lot about this, but they can be catalogued according to chemical
type. Whether they are a new molecular entity that's never been used before, whether they are a
new derivative of an older compound or a new formulation, such as an old drug in the skin
patch and a new way to present that drug to the public. or a new combination to drugs not
marketed the floor or an already marketed drug product, where the patents have expired. or a
