FDA Panel Nixes OTC Singulair

Published: May 2, 2014

Montelukast (Singulair) should not be authorised over-the-counter use for grain heat and other top respiratory allergy symptoms, an FDA advisory row endorsed Friday.

The advisors voted 11-to-4 opposite a risk-benefit ratio bargain of OTC use to provide nasal congestion, runny nose, itchy, flowing eyes, sneezing, and prickly of a nose in adults.

The opinion was further 11 no’s contra 4 yes’s that OTC use would be safe, deliberation a intensity for off-label use if a FDA followed a certain recommendation from a advisory committee, that it customarily does.

The prejudiced switch from remedy to OTC use (trade name Singulair Allergy) was due usually for adults during a once-daily 10 mg dose, while a drug would sojourn underneath remedy for a now authorized denote for anniversary allergic rhinitis in children as immature as 2 years and comparison and for long-lived allergic rhinitis in those as immature as 6 months.

However, a estimable suit of stream remedy use is in children, that a row voiced regard could meant unintended OTC use in that group.

A investigate in teenagers ages 15 to 17 submitted by drugmaker Merck to support a focus showed that too many teenagers suspicion it was right for them to use, notwithstanding labeling usually for adults.

The reduce firm came in during 80% scold answers contra a aim of over 90%, nonetheless a teenagers did accommodate targets for grasp of warnings for neuropsychiatric events.

That risk was also a regard discussed by a panel.

Montelukast poses a significantly larger risk than existent over-the-counter allergy medications, Michael Carome, MD, executive of Public Citizen’s Health Research Group, argued during a open open conference apportionment of a discussion.

“Among a side effects: agitation, assertive behavior, anxiety, depression, hallucinations, insomnia, rancour and suicidal thoughts,” he warned. “If people could buy Singulair though a prescription, a intensity for inapt and potentially dangerous use is high.”

While montelukast is differently generally safe, “you can suppose that would be concerning for a medicine to not be wakeful of if it was function to their patient,” Tara F. Carr, MD, executive of a adult allergy module during a University of Arizona College of Medicine in Tucson, concluded in an talk with MedPage Today.

A tag grasp investigate in adults with allergic rhinitis showed that scarcely all accepted a warnings about changes in mood, behavior, or thoughts or changes in nap that a FDA has warned about with this class, both questions assembly a 90% threshold for reduce bound.

Montelukast would have been a initial in a leukotriene receptor criminal category to make a switch from remedy to OTC.

Other OTC treatments for allergic rhinitis embody verbal antihistamines, verbal combinations of an antihistamine and decongestant, intranasal decongestants, intranasal cromolyn, and an intranasal corticosteroid.

Having another category of drugs accessible would be an advantage for patients, George Philip, MD, an allergist and executive executive of clinical investigate and product growth during Merck.

He cited studies display that scarcely 40% of allergy patients switch among medications, and about a entertain aren’t confident with their medication.

“Over-the-counter therapies have been personification an increasingly critical role,” he told MedPage Today in allege of representing a drug before a panel. “Based on a labeling of those products, not all now accessible OTC products are right for all consumers.”

Moreover, for patients, cost is a separator to use, commented David Lang, MD, chair of allergy and clinical immunology during a Cleveland Clinic.

“When drugs go over a counter, frequently a cost goes down, it becomes some-more affordable, and some-more people have entrance to a drug,” he told MedPage Today.

The bigger regard for a panel, though, was montelukast would have been a initial OTC drug that’s also an authorized asthma controller medication.

Although due to sojourn underneath remedy for that indication, off-label use and a substantial overlie between a dual conditions lifted a complexity of a decision.

Up to 40% of allergic rhinitis patients are also estimated to have asthma; while adult to 90% of asthma patients have allergic rhinitis.

“The regard is that a use of a drug by patients in an unlimited conform might extend over allergic rhinitis, privately that patients might self-medicate and provide their asthma and check seeking medical caring and get into difficulty with their asthma,” Lang explained.

The self-selection and tag grasp investigate in adults with asthma showed that a infancy of patients rightly comparison themselves for use by allergic rhinitis status, though a aim of a reduce firm of during slightest 90% scold answers wasn’t met for bargain that a drug should not be used to provide asthma.

Merck also asked that a OTC denote embody “itchy, flowing eyes,” that has not been partial of a existent remedy labeling.

The justification to support an visible denote came from post-hoc research of a delegate endpoint in 3 anniversary allergic rhinitis trials.

Only one of a 3 trials showed a poignant alleviation in daytime eye sign measure (an normal of tearing, itchy, and red and pompous eyes), and that alleviation had an outcome distance of 0.14.

“It is misleading either a tiny change represents a clinically suggestive improvement,” a FDA staff examination noted.

Any applicable relations with attention a row members had were resolved by a FDA.

Philip disclosed applicable relations with Merck.
