Could it be motivated by making money on the alternative?
Just a thought.
Absolutely, could well be. Aspirin is cheap and effective for some things, we tend to overlook how good it is because it is so old...
Or, using something like Coumadin as an example, it could be trying to improve a blood thinner in a way that might minimize the problems of a previous medication. It has been a long time for me, but I recall Coumadin has to be carefully tailored and monitored to the individual which involves taking blood tests to see how things are going.
Lots of places to go wrong and have a bleeding problem.
A new medication that would be less “tailored”, require less ongoing monitoring, or be susceptible to serious side effects if things get out of whack wouldn’t be a bad thing.
