The drug industry is very different from other industries because of generics. The FDA has an approval pathway that allows you to say "my drug is identical to that other drug". Also, many states have legislation that
requires pharmacists to fill Rx with generics. Marketing won't do a whole lot to help that.
If the same thing happened to the tech industry, it would work like this... you create an awesome new gadget and a competitor creates a copy. The gov't certifies this copy as "exactly the same". When you go to purchase the fancy gadget at the store, the clerk automatically gives you the cheaper copy without even asking.
Again, not something marketing can help a whole lot with.
