Those are some pretty good points and I totally see where you're coming from, before I learned about these diseases in depth I had the same opinion. Take diabetes for example, type 1 and two are essentially opposite diseases but we've made pretty big advances in both. Right now there's a lot of research on type 1 diabetes and islet cell transplants as a cure. Problem is islet cell transplants are like any transplants, the body sees them as foreign so you need immunosuppressants to keep the graft alive. You're stuck with choosing between having a "cure" for diabetes but having the side effects of all these immunosuppressants (which can be pretty brutal) or taking the usually well tolerated insulin but still having the complications of diabetes in the future (eye disease, kidney disease, nerve damage 20 years down the road). With type 2 diabetes you're dealing with insulin resistance. There's drugs like metformin which can decrease the insulin resistance, but in the end unless someone changes their lifestyle drugs can only go so far. If there was a "cure" for diabetes you bet the pharma companies would be pushing it, not only would they make a killing but they'd end up hurting their competitors bottom line which would put them in a position to have the next big "cure" before their competitors could come up with anything.nowaysj wrote:Bfs - is that why the pharma companies have announced cures for diabetes, high blood pressure, cancer, ms, Parkinson's, Alzheimer's, HIV, freaking malaria? Anything? No, but they've totally licked that limp dick problem, with another twenty years of monopoly for the exact same chemical with a marginally extended release! Whooo, the system works!
I respect your opinions, you've always kept it relatively real, but I'm afraid you're falling into that white coat bubble.
Basically, if you think about it, the body is in equilibrium when we're born. As things start to get out of line we can try our best to fix it, but by trying to fix things we're inevitably going to make other things pop out of equilibrium (side effects). Parkinsons for example - it's a deficiency of dopamine in the substantia nigra of the brainstem (a very specific spot in the brain). The first med for this was simply a dopamine agonist which fixed the symptoms of the parkinsons but caused side effects of too much dopamine in the other parts of the brain. We saw that problem and a brilliant scientist somewhere made a drug that was more focussed on that one area of the brain (I can't remember the different names of these drugs, I'm not much of a neuro guy to be honest). Then some other brilliant person decided that neurosurgery and an implantation of a pulsing electrode in the substantia nigra might work. The pulsing electrode thing almost looks like a cure, when you see someone turn the electrode on and then off (they get a remote control incase they need to turn it off for some reason) it's like night and day, with it on you can't even tell they have parkinsons. Problem is neurosurgery is pretty risky and most people aren't going to be surgical candidates by the time their 60 or 70 when they develop parkinsons.
Another big problem is that people aren't willing to help themselves. We always learn to treat things first through a trial of lifestyle modification. For example high cholesterol and high blood pressure can typically be managed if someone keeps a good diet that's low in salt and exercises 30-60 minutes 4-7 times a day (not always, there's genetic conditions which cause each of these, but in 99% of the cases lifestyle management could work). Everyone agrees in the clinic that they're going to do these things but in the end they don't. I understand why, I certainly don't get that much exercise or eat very well because I just really don't have the time, and I"m also a bit lazy.
I'll also agree that pharma companies do sketchy things. I already outlined the escitalopram and citalopram bit up there, and there was more questionable stuff that made me angry like the whole Colchicine thing in 2009 (worth a read, really made me angry but then again nothing we could really do). I think a bigger problem however is the "free" samples that pharma companies give out. They will only ever give out samples of drugs they still have patent on. The family physician (who means to do well) will typically save the samples for patients who can't afford the drugs themselves. Problem is that if you stabilize a condition on one of those drugs, once you run out of samples you probably won't want to change to a different class of generic drugs because you don't know if they'll work as well or be tolerated by the patient. Therefore, the well meaning family doc ends up putting people who definitely can't afford the expensive medication on the most expensive medication for their disease. This has been a huge problem and in Canada (or at the U of C anyways) the school did a great job of bringing this to students attention so we don't fall into that problem when we're out practicing. We actually had a whole ethics class which taught us how pharma companies try to influence physicians and how to stay relatively bias free from their marketing.
Funny you brought up the Viagra thing. Believe it or not Viagra (and the other ED meds) are actually super useful in other situations too. They cause blood vessels to dilate so we use it as a first line treatment in people with pulmonary hypertension. Made me have a good laugh and then a second take when I did my NICU rotation, half the kids there were on Viagra, and it took me a little bit to figure out why the hell a 28 week preemie would need that

Personally I look at big pharma as a necessary evil. They definitely do sketchy things and they most definitely have some pretty questionable ethics. But if you look at the diabetes thing again, without big pharma we'd only have the original insulin which is short acting. Even with that insulin people with type 1 diabetes had extremely shortened lifespans. With the research behind long acting basal insulin we can mimic the bodies natural insulin patterns so that the complications of diabetes are 20-30 years down the road instead of 5 years down the road.
Also, contrary to popular belief, pharma can't "bribe" physicians with holidays or cruises (at least in Canada). The most the Canadian government lets them do is give us free lunch while they give us free samples and brochures about whatever new drugs there are. I'd also say that the majority of family physicians I've worked with do work on preventative healthcare (in fact, the family medicine program is being sold to us as being "specialists" in preventative care). Problem is that preventative care can only get so far and it requires co-operation on both ends. Sure over prescribing and over diagnosing occurs and I wish it didn't. I'll probably over prescribe some things at some point in my career too, but I think it's important to remember that most physicians really do just want to help in whatever way we can, no one goes into medicine thinking "I'm going to go out there and prescribe the shit out of all the meds I can so that the whole population is medicated for things they don't need."
