On Friday, Reuters released an unique report detailing the FDA’s new analysis on montelukast, introduced on the annual American Faculty of Toxicology (ACT) convention that week. The FDA’s exams reportedly confirmed that montelukast might enter the brains of rats; additionally they discovered that the drug might considerably bind to a number of receptors discovered on mind cells. Whereas extra analysis is required to grasp precisely how montelukast can elevate the danger of suicide and different psychological well being issues related to its use, the findings help the FDA’s latest choice to discourage prescribing the drug as a first-line remedy.

There are nonetheless essential items of the puzzle lacking, nevertheless. We’re undecided precisely how this binding results in the issues that some individuals expertise whereas taking montelukast.
