Nonetheless, even at the lowest range, say, Anavex treating only 2.5 million people a year, at an annual pills cost of $5/day ($1800 per year), this yields gross annual corporate revenues of $4,500,000,000.
this yields gross annual corporate revenues of $4,500,000,000. That’s $4.5 trillion, not billion. Pretty big number.
When your answer exceeds the entire annual US spending on Medicare/Medicaid maybe it's time to double check (total spending, not just pharmaceuticals). The error is that $4,500,000,000 is 4.5 billion not trillion
With 2.5 million patients per year, corporate revenues would be only $450,000,000; four and half million dollars.
Uhhh....$450,000,000 is four hundred and fifty million not "four and half" million.
