Asthma is one of the most common non-communicable diseases in the world. Approximately 30% of severe cases are associated with fungal sensitization, often associated with allergy to the opportunistic mold Aspergillus fumigatus . Leukotrienes, immunopathogenic mediators derived from the metabolism of arachidonic acid (AA) by 5-lipoxygenase (5-LOX), are often elevated in severe asthma. As such, these mediators are FDA-approved therapeutic targets of the anti-asthmatic drugs Zileuton®/Zyflo® and Singulair®/Montelukast®...

BACKGROUND: The high prescription drug cost in the United States may negatively affect patient prognosis and treatment compliance. OBJECTIVE: To fill the knowledge gap and inform clinicians regarding rhinology medications price changes by evaluating trends in price changes of highly used nasal sprays and allergy medications. METHODS: The 2014-2020 Medicaid National Average Drug Acquisition Cost database was queried for drug pricing information for the following classes of medications: intranasal corticosteroids, oral antihistamines, antileukotrienes, intranasal antihistamines, and intranasal anticholinergics...

UNLABELLED: Montelukast is a leukotriene receptor antagonist (LTRA) commonly prescribed for asthma, allergic rhinitis and sleep-related breathing disorders. Recently, some studies have reported several adverse events, such as neuropsychiatric disorders and sleep disturbances, among children. OBJECTIVE: To obtain more insight into the safety profile of montelukast for children with asthma, allergic rhinitis and sleep-related breathing disorders. METHOD AND RESULTS: We retrospectively studied all adverse drug reactions to montelukast among 385 children 6 months or older in six tertiary centers over a two-year period...

This study aimed to explore the potential of biopharmaceutics in vitro tools to predict drug product performance in the pediatric population. Biorelevant dissolution set-ups were used to predict how age and medicine administration practices affect the in vitro dissolution of oral formulations of a poorly water-soluble compound, montelukast. Biorelevant age-appropriate dissolution studies of Singulair® (granules and chewable tablets) were conducted with the µDISS profiler™, USP 4 apparatus, USP 2 apparatus, and mini-paddle apparatus...

Introduction Chronic urticaria (CU) is a common disorder that can significantly affect the quality of life. The goal of treatment is complete symptomatic relief. Conventional therapy, with antihistamines, is not always effective in all patients. Leukotrienes are believed to be involved in the pathogenesis of urticaria. Leukotriene receptor antagonists (LTRAs), such as montelukast, have been suggested as useful agents in patients with chronic idiopathic urticaria. Our objective is to document the efficacy of montelukast in our patients...

Oral montelukast (MTK) is prescribed to treat asthma or rhinitis, and is clinically investigated as new medication in the treatment of Alzheimer's dementia. Herein, in order to better patient's compliance, microsuspensions (MSs)-based oral liquid preparations of montelukast (MTK) were formulated with polymeric suspending agents including hypromellose (HPMC), and those drug-polymer interaction, physicochemical stability, dissolution, and in vivo pharmacokinetic profile was evaluated. When amorphous MTK particle was suspended in aqueous vehicle, it was readily converted into crystalline form and grown into aggregates, drastically lowering dissolution rate...

The U.S. Food and Drug Administration (FDA) became aware of postmarketing reports of neuropsychiatric adverse events with Singulair (montelukast) use in 2007. Over the years, the FDA has conducted reviews of the clinical trial safety data, focused analyses of postmarketing reports, and reviews of the published literature. These activities have resulted in successive labeling updates and public communications. However, there has been continued concern among stakeholders about the risk of neuropsychiatric events and the lack of awareness among prescribers and patients/caregivers...

SARS-CoV-2 causing coronavirus disease 2019 (COVID-19) has wreaked havoc during the global pandemic of 2020 infecting millions and leaving over a half million dead. As a new virus, not previously in the human population, but with similarities to other coronaviruses causing severe acute respiratory distress syndrome (SARS/ARDS), and no known treatments, the race to re-purpose existing drugs and to enlist novel therapeutics is underway. In the half-year since the first cases, we have acquired substantial knowledge of this virus and the clinical course of COVID-19 progression...

PURPOSE: Capsular contracture (CC) is a troublesome complication after breast surgery with breast implants, and the risk increases in breast cancer patients after radiotherapy. Studies investigating leukotriene antagonists (eg, montelukast, zafirlukast) found that the acellular dermal matrix (ADM) can help prevent CC. We aimed to compare the effects of ADM and montelukast on CC after irradiation. METHODS: Eighteen New Zealand white rabbits were randomly divided into 3 groups of 6 each...

BACKGROUND: Montelukast (Singulair) is a cysteinyl leukotriene receptor antagonist, used for the maintenance treatment of asthma and to relieve symptoms of seasonal allergic rhinitis and asthma, also used for exercise-induced bronchospasm. AIM: This study was performed to determine the prevalence of Montelukast use as an add-on therapy among Iraqi asthmatic patients on treatment. Comparing the effectiveness of regimens with and without montelukast. METHODS: This descriptive cross-sectional study was carried out on 73 Iraqi asthmatic patients on treatment of both sexes with age range (18-60) years old, attending Al-Kindy Teaching Hospital and Al-Zahraa Centre of Asthma and Allergy, Baghdad, for the period between February and March 2017...

INTRODUCTION AND AIM: The aim of our study was to analyse the public price of the montelukast sodium therapy in Hungary. METHOD: Data derived from the nationwide pharmaceutical database of the Hungarian National Health Insurance Fund Administration. We observed the turnover and price of the medicaments containing the active substance montelukast sodium from 2007 to 2015. Accordingly, our indicators were: consumer price, DCT (daily cost of therapy), co-payment, quasi co-payment, DOT (days of treatment)...

Chronic urticaria is a disease manifested by a pruritic rash lasting longer than 6 weeks that may severely affect quality of life and daily function. Chronic urticaria can be further divided into chronic spontaneous urticaria which appears without a trigger and chronic inducible urticaria which evolves following distinct physical triggers. These two clinical manifestations could coexist in the same patient. The pathogenesis of chronic urticaria is not fully elucidated, although it is considered an autoimmune disease in at least 50% patients that produce auto- IgG antibodies targeted against the high affinity Fc receptor and to a lesser extent against IgE itself...

BACKGROUND/PURPOSE: Asthma is a chronic airway inflammatory disease mediated by T-helper (Th)2 cells. Montelukast (trade name Singulair) is a cysteinyl leukotriene receptor antagonist used for asthma treatment. Mirroring Th1-Th2 polarization, two distinct states of macrophages have been recognized: the classically activated (M1) macrophages and the alternatively activated (M2) macrophages. M2 polarization is known to be a response to the Th2 cytokines; however, the effects of montelukast on M2 macrophages have not been well characterized...
