You can only sell medication after trials. The first trials were on young women, and later trials on other groups. Nobody wanted to pay for trials on all demographics before there was evidence it worked from cheaper, more focused trial. There are also barriers to doing trials on high risk groups like the elderly without first testing on lower risk demographics. This is one reason why so much medication not to be used by pregnant women. The trials have not been done, and trials involving pregnant women are particularly expensive and risky.
