This is a very old generic that one company has a monopoly on in the Untied States. It literally is pennies in cost outside of the United States.
If there was only one oil company in the United States and you were paying 150 dollars a gallon for gas, what would you say?
I am a total believer in free enterprise and capitalism. This is neither. This is a company buying up distribution rights and thus becoming a monopoly.
“This is a very old generic that one company has a monopoly on in the Untied States.”
If generic anyone can make it. How there be a monopoly?
You are confused about the word monopoly. This drug is off-patent. Anyone willing to establish a manufacturing line can make it and sell it. What excludes most from doing so is the regulatory, compliance, quality, legal, manufacturing, packaging, and post-marketing reporting obligations. All that requires an army of professionals to gain and keep FDA approvals.
If you truly discover a new chemical entity and file a patent you will have about 7 years of marketing exclusivity. After that anyone can gear-up to make and sell that drug.
