We already are leveraging the placebo effect, unfortunately we are also doing it in a negative way by highlighting side effects.
Plus, the act of noticing those extra effects can give you another placebo effect on top, e.g. if the medicine has some noticeable effect, the placebo can get stronger, or cause other effects to accompany it.
Of course there is also consciously learning to leverage the effects of the medicine, which is a non-placebo~
It's one thing if they tell me that a cup of tea helps some people with migraines, and is another thing if they're selling me sugar pills
I'm speaking from a non-American perspective.
I'm not saying anything about the profit motive. I'm saying that doctor should not lie and trick patients.
But modern treatments are evaluated based on having demonstrable net positive effects above and beyond placebo.
For those unaware, phenylephrine should never have passed FDA trials. It was whisked through almost certainly at the behest of Johnson and Johnson to provide a replacement for the very effective psuedoephedrine, which happened to be a relatively easy methamphetamine precursor.
Then, for J&J to have the gall to market phenylephrine as "Sudafed" was just the cherry on top. I wasn't aware of all that at the time, but the first pill out of a box of new Sudafed was so ineffective compared to the previous pill from the old stuff that I had to look it up.
I found this to be a good read/overview:

The short version is that we do use it in some cases where there's a lack of other options. E.g. I can walk into the major pharmacy down the street and buy "earache medicine", which is (almost literally) just water. My insurance won't pay for something like acupuncture right now, but if I were undergoing cancer treatment, suddenly things like that would be partially covered in the name of "pain relief".
I guess that could be true in a very specific subset of medicine, but I cannot imagine that is true in general. As others are mentioning, the placebo effect already is part of the medicine, except in cases where the patient is medicated while in coma or things like that.
Do you have evidence to support your claim?
That the work is necessary doesn't make it not part of the challenge.
How are you defining "difficulty" here?
Paying people to do the testing properly and, collecting and organizing the results. Making all those schedules. Making sure that the math needs is solid. Founding volunteers. Etc. All of that. It costs a bunch of money.
In the abstract, it could be said that it is a difficult process. I would not would not be able to organize it.
But for the people who are involve in those tests, and that have done that kind of thing hundreds of times, that is not a difficulty. It's routine.
If we are going to define "a difficulty" that way, then anything that a big company does is "a difficulty".
Yes, successful pharma companies are good at overcoming the challenges involved, some of which you listed. The point is that being able to do so is necessary for that success, and thus, an obstacle.
Only if neither the patient nor insurance are paying for it. Otherwise that's just straight up grift.
