it’s available as a generic, so probably no money to be made on this one because more than one co is manufacturing it.
I hear you on the inhalers. Buy Canada - three months w/shipping for less than one month stateside (current law allows up to 3mo supply to be imported - might be six now?). And I don’t feel guilty in the slightest as I drive right past those highway robbers Walgreens and RiteAid and the rest on the way to the post office to pick up my little Canadian Post package.
It's legal (but shouldn't be but Congress sold us out) for one company to PAY another company not to manufacture a drug off patent.
