“I think generics can only come out 20 years after invention of the drug (google)”
that isnt quite right. After 20 years from when a atent is submitted the patent is expired and anybody can produce the drug. (note: this clock starts several years befoe the drug actually becomes available, since the patent is obviously submitted relatively early in the development process)
Though you are right. the 7 year refers to exclusivity in specific cases and isnt generalizable.
“What do they do once generics come out if most/everyone only bought generics since it’s so much cheaper”
for any number of reasons. people think its better, name recognition. I (and many I know) refer to generic acetaminophen as “tylenol” much as many refer to any bandage as a “bandaid” Dominos sugar produces most of the “generic sugar” available in your grocery Yet many pay mor for the “brand name” sugar from the same plant that they insist tastes better.
“Again unless there are specific circumstances that brands are required,”
Again these exist, but are few and far between.
“if people knew…”
Yes, but many dont
” So how can it be that brand name drugs have pretty much no advantage over generics and don’t differ? Or do they?”
I lost you here. They do have an advantage. Isnt that the point of your thread?
Now I dont think anybody says alleve tastes better than naproxen. but it certianly has better name recognition. As mentioned if I want my wife to pick up acetaminophen I ask her “please pick up tylenol” she knows I mean generic. These companies like Coca cola spend years developing their “brand”. Many refer to any cola drink as a “coke”
