Singulair and circumstances

I am posting the metabolism profile for montelukast. Maybe someone here has chemist friends who might know if it is possible that the dicarboxylic acid major metabolite could also have been derived from quinolinic acid under metabolic circumstances less than ideal. The quinoline ring, is a benzene-pyridine. Quinolinic acid, a dicarboxylic acid with a pyridine is produced by the oxidation of quinoline possibly by acid hydrogen peroxide. So the only structural difference between the dicarboxylic acid mentioned in the study as the major metabolite and quinolinic acid is nitrogen. Fascinating drug Singulair. Macrophages (immune cells) make quinolinic acid and release nitric oxide in order to kill micro-organisms. Quinolinic acid a neurotoxin.

Unless you are someone who plans to get help from experts, I would ignore this post. In my opinion, the only way that real answers will come from the investigation is that there is a provable chemical reason that the brain is affected by Singulair. I just post what I find and hope that eventually there will be experts who can explain why people are having such problems. I am unable to draw any conclusions from the report below.

Here's a way out theory about my unique and to me mystifying medical situation....

I recently read where Singulair, an asthma medicine, is suspected of causing suicides, obviously an effect on the brain function. The FDA notes that over the past year, Merck has updated Singulair's prescribing information and patient information to include the following post marketing adverse events: TREMOR (March 2007), (April 2007), suicidally (October 2007), and anxiousness (February 2008). (the tremor highlight is mine since this is a major symptom of Parkinson's )

Well, I took Singulair from 1998 to 2004 and I wonder if maybe, just maybe Singulair could be a contributing factor to my strange Parkinson's but not Parkinson's problems that is
gait,
balance,
freezing of gait problems

Any thoughts or ideas on how I might follow up on my hypothesis?

I have to say this after reviewing two major areas:

1. the brain
2. mast cell homeostasis

I desperately wanted to be POLITICALLY CORRECT and say that side effects can be confined to the minority. God, how do you fight Merck?

In this case, it would seem that the real benefit of this drug is to those with the extreme type immune responses whose body chemistry has been altered by being hyper-sensitive to some type of "invader. Extreme can be defined as just not the average or beyond that.

So, if the truth comes out that essentially normal immune systems don't need Singular at all, then I have come clean. I certainly have doubts whether essentially normal systems need this at all.

My 2 year old son has only been on Singulair asthma for 4 days(since Friday March 28th), but he will not be taking it anymore. We have noticed a HUGE change in him in those 4 days. He is having mood swings like you wouldn't believe. One minute he's ok, then the smallest thing will trigger a terrible tantrum, then he has his clinging moments like he's seeking security where he just clings to me. This is totally not normal for him. My parents also noticed a changed over the weekend. He is normally the perfect angel for them, yet threw tantrum after tantrum while they had him. I'm so glad that I thought about his actions being a side effect of the meds and found this website. I'm horrified at all of the circumstances I've read about on here and I hope that all these children who have been on it for years have no long term side effects from the meds. I am currently awaiting a call from the doctor to find out what medicine they recommend to replace it with.

Our 7 year old son has been old singulair since he was about 3. I can't even describe in words how I feel as a parent knowing now what my son has been going through. He (just like the others) has been very emotional and become very timid and has had a couple of panic attacks. I really began noticing it when his doctor bumped up his dose several months ago. He began talking about death and morbid things quite frequently. His doctor also has diagnosed him with ADHD. Over the past several months I took him to the doctor for extreme leg pain and once to the emergency room for crippling abdominal pain. They couldn't find anything wrong with him. We've taken him OFF of singulair forever and few days ago and him bright and positive personality seems like is beginning to come back. I just hope that he has suffered long-term damage from taking this medicine. At this point, we can only hope and pray that everything will be fine.
