Leukotriene modifiers symptoms and conditions

Unfortunately my lawyer told me that they do not want to take our case because of the lack of evidence that Singulair has caused our daughters problems. :(

Does anyone out there have a pending class action lawsuit that We may be able to get in on? I have tons of proof that Singulair has caused our daughters problems and loss of almost 5 years of her elementary school career!

My phone number is *** and my email is ****** if You email me please put "Singulair" in Your subject line so I know it pertains to this posting.

Thank You in advance,

Effective after two weeks for some people - not effective for others. Side effects for some people - others do not report side effects. So why does Merck have to grow their market before they have any idea what's going on?

This isn't a big group of people in the study but it makes sense from what we are reading here. These researchers did examine the mast cells. We need to know about mast cells (while suppressed by montelukast) on a longer term basis.

The efficacy of montelukast and airway mast cell profiles in patients with cough variant asthma.Kawai S, Baba K, Matsubara A, Shiono H, Okada T, Yamaguchi E.

Background. Cough variant asthma (CVA) is characterized by chronic cough without apparent wheezing; its pathophysiology is considered to be similar to that of classic asthma. Objective. The clinical effects of montelukast, a cysteinyl-leukotriene receptor antagonist, on cough variant asthma were assessed, and the activation profile of airway mast cells was examined. Methods. Montelukast (10 mg/day) was given orally to 36 CVA patients (25 women and 11 men; median age, 37.5 years). Before treatment, the patients' bronchial mucosa underwent a biopsy with a fiberoptic bronchoscope. The biopsy specimens were double stained with anti-CD63 antibody and anti-human tryptase antibody. Results. After 2 weeks of montelukast treatment, cough symptoms improved in 22 patients (the effective group) but did not improve in 14 patients (the ineffective group); in the ineffective group, the symptoms disappeared 2 weeks after they were switched to fluticasone propionate (400 mug/day) inhalation therapy. In the effective group, the time interval from the onset of symptoms to the initiation of treatment was significantly shorter than in the ineffective group. The bronchial mucosa biopsy specimens showed that the proportion of CD63-positive cells in tryptase-positive mast cells was significantly higher in the effective group than in the ineffective group; although the total numbers of mast cells were not different between the two groups. Conclusion. There is a subgroup of CVA patients in whom leukotrienes are closely involved in the pathogenesis of their chronic cough; activation of airway mast cells may be an essential feature in these patients.
