Citizens symptoms and conditions

Sorry, I can't just walk away.

When you find patents or patent applications for certain purposes, then you know that your ideas are well founded. There are several patents for using an anti-malaria drug for asthma. I would bet that somebody had that idea all the way back to the 1960's. So it is very possibly no coincidence at all that a chloroquinoline or other quinoline ring would be part of montelukast's chemical structure.

Here is one of the patents.

It is well known that quinoline rings can be toxic to some people even very rapidly. As in this very extreme example.

FATAL ACUTE CHLOROQUINE POISONING IN CHILDREN
Howard M. Cann M.D.1 and Henry L. Verhulst M.S.1

Four cases of acute chloroquine poisoning in children are presented. In three instances death occurred within 2 hours of ingestion of larger than therapeutic amounts of the drug. The rapid occurrence of death in acute chloroquine poisoning is probably explained by complete and rapid absorption of the drug from the gastrointestinal tract resulting in high blood concentrations which depress vasomotor function and respiration. Cardiac arrest follows and may be caused by the direct myocardial action of chloroquine, to anoxia, or to both. The similarity of the manifestations of acute chloroquine poisoning and those of acute quinine and quinidine poisoning suggests that acute toxicity may be attributed to the quinoline ring portion of these drugs.

I don't think that we are seeing extreme examples. But we may be seeing less extreme immediate reactions or reactions where the toxicity builds up over time.

Quinoline rings are know to cause neurotoxicity. There are theories about how that happens. One of the theories is about blocking connexins which are gap junction proteins in the brains.

I don't know how montelukast could be breaking up so that it causes toxicity. Or if the problem is the how rapidly the liver enzymes can metabolize it. But there is plenty, plenty, plenty of clinical evidence that there is a quinoline ring culprit somewhere in the picture. Or some by-product of that causing problems.

Somehow it was decided that montelukast did not have the safety issues that the other drugs in the same category have. See this.

"The starting point in the development of montelukast appears to be a quinoline-containing structure, likely identified as a weak random screening lead (Figure 3). The Merck group hypothesized that this molecule was mimicking the olefin backbone of cysLTs, and that the addition of mimics for the acid and peptide regions of LTD4, might improve its potency. As a first step, the dithioacetal linkage first seen in some SmithKline compounds was incorporated; this led to a compound with greatly increased in vitro potency but poor oral bioavailability. When one of the carboxylic acids was replaced by an amide, forming MK-571, the new antagonist had even greater potency and good efficacy following oral administration. The enantiomers were resolved to yield MK-679 (verlukast), a compound with better clinical effects than MK-571, but whose clinical development was stopped for safety reasons. Further structure-activity relationship studies led to the development of montelukast (16), an antagonist that appears free of the safety concerns plaguing earlier members of this series."

If we can find out why the earlier versions were not safe and how they thought fixed it, then maybe we can find out what is going on with the quinoline ring in some people.

I would be very surprised if the FDA will address our concerns. Why does it always seem like they wait for enough people to die like in Vioxx? Wasn't Vioxx responsible for thousands of deaths?

UPDATE: Our nightmare with SINGULAIR has not ended! After reading "conerned citizens" report discussing the possiblility of Singulair causing asthma blew me away. My son was put on this drug for food allergies not asthma b/c they thought of his two anaphylaxsis episodes in 5 days. 1 food related the other unknown (maybe outdoor mold?) He had no prior issues with breathing.

He has been off of it for almost 2 weeks however over the last week he has slowly developed some breathing issues. After getting off of it, he still has his ear infection from the second day of being on it and last Friday after playing some basketball began to seem like he was winded so I brought him in. He was having trouble breathing. I called the Dr. and he said it could be excercised induced asthma. He is a very active boy who runs non stop and has NEVER had breathing issues before Singulair! It seemed to pass after a few hours. The next fews days he coughed a few times when playing and I thought what the heck is happening to him. Monday at school they didn't go outside so he was fine b/c he didn't run around. Tuesday, they came to get me b/c he was having trouble breathing and one of his teachers whose son has asthma said I think you better give him an inhaler. I called the Dr. ASAP and he approved us to borrow another child's. He freaked out and wouldn't let us give it to him. After 2 epi-shots in the previous weeks, he wanted nothing to do with that. At school the next day, we made him take the inhaler if he wanted to go out to playso he did. He didn't cough but a few times. No excercise at all. Then last night, he got really bad. He started to cough and couldn't stop to the point of gaging and it seemed as though he had developed a ton of phlem and kept trying to swallow. We ended up in the ER where we were told that he has asthma! I am so furious! I don't get this at all! If this report is accurate and my son got asthma by going on it - this will be devastating. We kept him home today from school and took him into the Dr. b/c he continued to cough all night. He is now on Flovent, Albuterol and has an enebulizer. I'm probably the only one of all of us who child did not have asthma to begin with.

Has anyone who did not have asthma before singulair now have any issues? Please let me know!

I cannot believe that there is so much of ignorance in such an educated society. Let me first start by saying I am on no medication absolutely I do have bronchitis I don't take cough medications or allergy medications or inhalers etc etc. I read at the bottom in a post that this 28 year old cries every time she sees te Save the children advertisement. I can tell you I listen to music, I watch tv and every touching or heart rendering story or lyric makes me cry!!! I wonder if i was on Singulair I would certainly be committed to some mental asylum.
I think all you educated people should consider that you do not need to be on a drug or any medication to suffer from depression symptoms or any such other emotional trauma. Why blame one thing alone, blame the governments for putting its citizens under stress , blame your economies for bringing down your county into a recession where your earnings don't meet the cost of living, What we should be fighting for is irrelevant, so some strategy comes into light where all these years, read all the posts, 2 , 5, 7 10 years of using Singulair and NOW you want to complain. Why didn't they complain all these years ago and get the drug recalled.. Don't blame one thing alone. Maybe if people lived cleaner, healthier lifestyles you wont be taking medications.
