My problem with pharmaceutical companies are these me too drugs/clones/isomers.

Here are some examples from mental health from memory.

Celexa/Lexapro
Effexor/Pristiq
Risperdal/Invega
Abilify/Rexulti

In terms of effectiveness, there’s almost no difference. Complete money grab. I think the term “evergreening” is used.

There are exceptions, but not many.

One exception is the upcoming antidepressant esketamine, which is the enantiomer of ketamine. This will be a big deal because regular ketamine will never get approved for depression.
