For decades , multitude with asthma have turned to the drug montelukast for relief . But new datum pull in by the Food and Drug Administration is the latest to show this discourse is more dangerous than once take on — particularly to our brain .
On Friday , Reutersreleasedan exclusive report detailing the FDA ’s raw research on montelukast , presented at the one-year American College of Toxicology ( ACT ) conference that hebdomad . The FDA ’s tests reportedly showed that montelukast could enter the brains of lowlife ; they also base that the drug could significantly bind to several receptors find on brain cells . While more research is needed to realize on the dot how montelukast can lift the risk of felo-de-se and other mental wellness problems associated with its use , the findings support the FDA ’s late decisiveness to warn dictate the drug as a first - line treatment .
Montelukast was in the beginning developed and sold by Merck , under the firebrand name Singulair . Approved by the FDA in 1998 , the anti - inflammatory drug — take an once - day-after-day anovulant — became a keystone treatment for millions , helping many citizenry foreclose and control their symptom of asthma and other allergic reaction . But over the yr , some affected role and their menage began to account unusual sequence of aggression , depression , self-annihilation ideation , and other neuropsychiatric symptoms that emerged only after they pop take the drug .

The FDA firstcaught windof a likely radio link between montelukast and these symptoms in 2008 . As a event of their initial investigation , the FDAmandated new labelingon montelukast and like drugs that disclosed these possible risks . But the incidents continued to pile up , and by 2019 , thousands of account on montelukast had been charge to the FDA . Between 1998 to May 2019 , the FDA had received 82 report of self-destruction tied to the drug ’s use , with about a third necessitate kid under 19 .
In March 2020 , the FDAdecidedto supply a black loge warning , the strongest eccentric of warning , to Singulair and its generic versions . The new labeling more strongly emphasized the likely risk of self-destruction and other mental wellness effects from take montelukast . The FDA also determined that montelukast should no longer be a first drug of pick for people with allergy or asthma , particularly if their symptom are meek . Rather , people should only expend it if other treatments have die to help them .
former research has shown that montelukast can reach the brain . But the FDA ’s young determination that montelukast can significantly bind to encephalon prison cell sensory receptor is important since it ply a potential explanation for how it can induce mental health problem . Another key point is where the drug was found accumulating in the brain .
“ These data indicate that montelukast is highest in brain regions known to be involve in ( psychiatrical effects ) , ” said Jessica Oliphant , a surrogate director at FDA ’s National Center for Toxicological Research , at the ATC conference talk about their findings , according to Reuters .
There are still crucial pieces of the mystifier missing , however . We ’re not sure just how this hold fast lead to the problem that some people experience while taking montelukast . And while cases of severe mental illness from montelukast may be rare , we do n’t know if some mass are more susceptible to the peril than others .
For now , at least , the situation surrounding its use will stay the same . An FDA voice told Reuters that the raw data would not exchange the FDA ’s current black box labeling of the drug . Merck did not respond to a request for comment from Reuters , but Organon , a spinoff of Merck that now markets Singulair , did , stating : “ The product label for Singulair contain appropriate data regarding Singulair benefits , risk of infection and reported untoward reaction . ”
Merck may yet have to answer for its original handling of the drug . The company is reportedly still facinglawsuits from affected patients , some of which have say that Merck knew early on on about the mental health symptom consort with the drug and by choice downplay their existence to health regulators .
