I suggested doing this exact study to one of the urology/sex/impotence researchers at UCLA about 3 days after the connection between NO and erection hit the papers. He agreed it would be an interesting study, but wasn't too excited about it. No drug company was going to give him money to study arginine, I guess. BTW, it also occurs to me that there is absolutely no reason, given these studies, to imagine that arginine supplements should not also have treatment value in mild cardiac angina-- the kind for which nitroglycerine patches or nitrate pills are prescribed now. It's all the same mechanism. Steve Harris, M.D. From: sbharris@ix.netcom.com (Steven B. Harris ) Subject: Re: Yohimbine, Minoxidil and NO ...

A good stiff snort or taste of nitroglycerin causes a terrific headache in most people, not just migraine sufferers. The body adapts after time to that effect, or most people with coronary disease would not be able to stand their nitrate treatment. Years ago (I heard this in medical school in the early 80s) cardiac patients discovered that their nitroglycerin paste could be used directly on the penis to give them erections (an early nitric oxide treatment as it now appears), but if they didn't use a condom, the result was a really terrific headache for the female partner. No reports about whether the [skull] "popper effect" (NO or nitrite vasodilation enhanced orgasm) was consolation enough for this. Timing here, I imagine, would be a bit difficult. It's not for nothing that poppers (alkyl nitrites) as recreational drugs are sniffed. Steve Harris, M.D. From: sbharris@ix.netcom.com(Steven B.

I would say immediate IV methylene blue, a treatment sometimes given for met-hemogoblinemia. But it is a little known fact that methylene blue inhibits cGMP signal transduction, an overdose of which is the problem with too much Viagra. Of course, this is all theory. Still, methylene blue (which turns urine bright blue) is innocuous stuff (as many a college prankster can testify). In the medical pipeline are various NO (nitric oxide) synthase inhibitors and NO scavengers. None are available commercially as drugs, due to red tape wrapping of our lovely FDA. All would be useful in Viagra overdose. There are a number of cheapy chemicals available from Sigma which we use in dogs to keep blood pressure up in conditions of NO overdose (from shock). But if I gave such a thing to a person, even somebody dying of hypotension from Viagra, they'd probably have my license. So in a standard medical setting it would be Levophed (norepinephrine) and MAST trousers. Steve Harris From: sbharris@ix.netcom.com(Steven B.

Nitric oxide is the premier signal molecule of vasodilation, inflammation, and the processes triggered by inflammation, such as healing and immune activation. It's why nitrogylerine works, and nitroprusside. It's a major mediator of septic shock and reperfusion injury in tissues like the brain. It's in the middle of most important pathogenic processes, somewhere. It's a tremendous discovery, and certainly deserved the Nobel. Viagra is the tip of one very big iceberg.

So, if you're at cardiovascular risk, it makes sense to get some kind of stress test before you use Viagra. Due to the nature of the drug, I'd recommend a persantine-perfusion scan. Viagra works something like persantine, so if you survive the one without ischemia, you should survive the other. I've suggested to the maker that it ought to test and market an IV form of Viagra, to be used for chemical heart stress testing, in place of persantine. Basically, a Viagra-scan. That would be the ultimate screening test for men who worry if the phosphodiesterase-inhibitor type vasodilators are safe. The drug company actually liked my suggestion, but I bet nothing comes of it. I mean, I recommended the hooker-stress-scan and the mistress-stress-scan years ago, and it never caught on. The FDA wanted Phase I trials, and it was all a mess. What can I say?

COMMENT: Yep, Viagra can really stiffen you out sometimes, all right-- to do any better, you have to go on with cryonics. I've recommended to the Viagra people that they develop seldenafil as a cardiac stress-test drug, much as persantin is used for that now. It puts your ticker under load, but there's a lab and a bunch of docs watching you, so it's a much safer proposition. It should work fine for the purpose, and would be the perfect screen for people who are going to start using it as a sex drug. And you'd catch a lot of early and undiagnosed heart disease that way, as well. It really is a crying shame the way the stuff is being promoted. More than half of men who have difficulty getting an erection have the problem because they have beginning to develop atherosclerosis, and don't know it. I know urologists convinced that this "sign" is a far more sensitive one and more specific one than angina, and maybe as worrysome as a positive stress test. New erectile dysfunction should trigger the full cardiac workup, probably. Instead, it triggers some guy to go down to get a free sample of something which his doc may not require him to get the screens for. Which he generally uses for some strange and new woman that he's worried about impressing (his wife already knows he sometimes can't perform), and the combination of excitement and the new drug does him in. Here we have the US surgeon general, whose job it is to tell the public such important stuff. Like: "Hey, bub. If you think you might suddenly have the need for Viagra, maybe it's time you got checked out for heart disease. See your doctor." Instead, we have TV commercials fueled by ungodly amounts of pharmaceutical profits in which we have some guy who looks about 35 except for the touch of Grey, putting on his necktie for that hot date (with the wife <g>), hawking a molecules which is ACTUALLY going to be used by 50 year-old obese diabetic businessmen at some hardware convention, a thousand miles from home where the wife still is. I've thought about putting together a $1000-callgirl scan as a similar screen for such men, but suspect that society isn't ready for that. I think you could save some lives that way rather pleasantly, but the insurers would balk. Say, have you heard there's another generic coming along in this same family, called mycoxsadril?

Viagra is hardly one of >the more obvious nor deserving targets. Well, actually it is, but it's hard to know who to blame. We tolerate some direct targeting of Rx drugs to consumers in the US, and the price we charge for the information distortion this naturally causes, is to make the drug companies do a bit of public service education at the same time. But it's obvious that this kind of thing is not working as intended when our TV commercials for birth control pills for women (for example) contain stuff like "Birth control pills will not prevent HIV or sexually transmitted diseases" (now there's a newsflash), as well as the heavier stuff like "Women who smoke should not use the pill, or generally women over 40; and possible side effects include clots in the lungs, stroke, heart attack paralysis, death and have a nice day..." While at the SAME time commercials for Viagra have next to no warnings at all. And certainly don't mention the important point that most impotence in men is connected to atherosclerosis, and ought to make any man who is using erectile aid drugs think about having a complete cardiovascular workup, if he hasn't already. The FDA message here is very clear: we don't see a woman who has a stroke while using an oral contraceptive in the same political light as we see a man who has a heart attack because he's in the wrong group to be using Viagra. We should, however, because there is no difference. I am merely recommending the same sauce for the gander as for the goose, as it were. >And you have some magic solution to atherosclerosis? Some other pill >that makes the plaque disappear and the arteries become flexible? >What's the point? The point is that we're quite close to having just such stuff. Dying of a big sudden MI in middle age in an affluent western country is now more a matter of incredibly bad luck, really really bad genes, or shear stupidity-- sort of like losing all of your teeth in this modern age of dentistry and periodontics. Atherosclerosis is not like metastasized pancreatic cancer-- it's in general now a very treatable problem. With smoking cessation, proper diet, and drug treatment most people can now put their coronary risk factors exactly where you want them. You can also take aspirin and other preventives, as well as get a stress test (and angiography and even surgery if necessary) to give them some idea of how much time and room you have to deal with the problem, and/or give them the time if they need it. Under such conditions atherosclerotic lesions DO stop growing, and often actually regress. Proper treatment makes a tremendous difference in risk of future MI. There are no guarantees yet, and regression doesn't happen immediately, of course. But it's quite common to see studies in which risk of future MI in treatment groups is cut to a tiny fraction of placebo; and I've no doubt the odds are higher yet for combinations of treatments with regard to no treatment (which is what you get if you ignore warnings like impotence). They don't do such studies because with what we know by now about treatment of atherosclerosis, they'd be immoral. In any case, you see the point. This is something you want to know about. As you pelvic arteries now, so go your coronary arteries tomorrow. >No doubt Pfizer is making a bundle off Viagra at a non-insurance- >reimbursed (mostly) $10 per 100mg but I say thank god for Pfizer and >for Bob Dole. They should get the nobel prize! Even apart from the >medical effects of Viagra, the wonder drug, they deserve credit for >taking impotence our of the shadowy world and establishing it as a >condition to be treated and researched just the same as--oh, let's >say--asthma, or at least acne. The point is that Viagra doesn't treat the problem, which is (too often) pelvic atherosclerosis. It treats the SYMPTOM. Sometimes the only symptom some of these men will have for years-- until they get the big MI. If somebody had just discovered nitroglycerin pills, and the company had Bob Dole come on TV and say: "Say, men, do you get chest pain sometimes when shoveling snow? Try a bottle of THESE. They work for me when MY chest hurts during exercise." Then you'd get it. Wouldn't you? This is not to say that nitroglycerin pills are not a good thing. They are. When used by people who know what they're doing. But if some company should really try to market nitrates that way to people with the "problem" of chest pain, like the problem of impotence, the FDA would go bananas. They don't think about Viagra the same way. They probably should.

Of course I have no objection if it's done this way. But it's not. You see the young guy on the Viagra ads, who can't be more than about 40 and isn't 5 lbs overweight, and you might get the idea that impotence is just something that naturally happens to large fraction of men as a result of being over 35. No big deal. Nothing to get embarrassed or even worried about. Doesn't mean you're sick. Just see your doctor and get the fix pill. Well, it is something to worry about. And it may well mean that you're sick as hell, and in fact you're (technically) dying. You're no younger than your arteries, and some of your better arteries are complaining. And sure, you can take the Viagra and ignore all this. Great. Just so you don't say we didn't tell you. SBH |
