Insurance companies do not want cheaper care.
In the US, insurance companies must spend 80% of premiums on care. So if you pay $1k/mo, they have to pay out at least $800/mo in care. (Not to you specifically, but averaged out across all subscribers.)
This is a cap on their potential profits. They always have to pay out 80% of premiums for care, so how do they make more money?
Well, imagine care is twice as expensive. Instead of paying $800, they have to pay $1600. That sounds worse, but, instead of $200/mo, they now $400/mo for themselves!
So, no, paradoxically, it is not in the interest of people paying for the treatment to save money. Quite the opposite.
I'll assume they're on company insurance. Which is often "self-insured" in that the company actually foots the bill as opposed to the insurance company.
Why don't corporations just drop insurance companies that decide to not allow cheaper medicines?
The 80% rule has a lot of loopholes. It doesn't apply to employer funded plans. There's a reason UNH is so big!
Why is there a continuous stream of healthcare providers threatening to or becoming out of network for various managed care organizations because they cannot come to an agreement on healthcare prices?
The FDA's policy for the last couple of decades is that mixtures of mirror images will not get FDA approval unless there is a strong rationale for it.
Racemic mixture of ketamine was approved decades ago. If you want a new indication for ketamine, you will need to get approval for a single mirror image, as the FDA won't approve the old drug.
They did this because there are numerous examples of racemic mixture drugs having increased side effects from the less active mirror image, so the FDA decided no more racemic approvals.
My guess is your insurer would be happy to pay for the old version, but your doctor is heavily incentivized to use the new version as the markup on the drug is much, much higher.
Esketamine is their cutesy way of saying the word s-ketamine. The s- comes from the Latin word "sinister" which means this is the left-handed enantiomer, not the right-handed one.
It is stupidly expensive, given how generic ketamine itself is. In our case, sleep apnea treatment proved to be a much better option than that drug, as it was just hiding an underlying condition and the treatments only last for maybe a week or two anyway.
I think there have been some people using ketamine off-label, but I don't know much about that. It does need to be tightly controlled because it can cause breakthrough psychosis in some patients. They try to screen those out, but that's not as effective as one might hope given my experience of seeing that fail. And it that was very nearly a fatal mistake.
