BACKGROUND: It has recently been shown that the leukotriene receptor antagonist montelukast rejuvenates aged brains in rats. The question is whether this commonly used, systemic, anti-asthmatic medicine has a similar effect in humans? RESULTS: We approached this issue by doing statistical analyses based on the Norwegian Prescription Database. The Database lists all prescription-based medications in Norway, but not drugs given to people who are in hospitals or nursing homes...

OBJECTIVE: Asthma is a chronic inflammatory airway disease induced by many environmental factors. The inhalation of allergens and pollutants promote the reactive oxygen species (ROS) production leading to airway inflammation, hyper-responsiveness and remodeling in allergic asthma. The effects of asthma medications on ROS production are unclear. The present study investigated the anti-ROS effects of current asthma medications including inhaled corticosteroid (ICS; budesonide and fluticasone), leukotriene receptor antagonist (LTRA; montelukast), long acting β2 agonists (LABAs; salmeterol and formoterol) and a new extra-LABA (indacaterol)...

Developing novel chemo-prevention techniques and advancing treatment are key elements to beating lung cancer, the most common cause of cancer mortality worldwide. Our previous cohort study showed that cysteinyl leukotriene receptor antagonists, mainly montelukast, decreased the lung cancer risk in asthma patients. In the current study, we conducted in vivo and in vitro experiments to demonstrate the inhibiting effect of montelukast on lung cancer and to investigate the underlying mechanisms. Using Lewis lung carcinoma-bearing mice, we showed that feeding montelukast significantly delayed the tumor growth in mice (p < 0...

BACKGROUND: Viral infections are the most common triggers of asthma exacerbation, but the key molecules involved in this process have not been fully identified. Although cysteinyl leukotrienes (cysLTs) have been postulated as the key mediators, their precise roles remain largely unclear. To investigate the roles of cysLTs in virus-induced asthma exacerbation, we developed a murine model using a viral double-stranded RNA analog, polyinosinic-polycytidylic acid (poly I:C), and analyzed the effect of leukotriene receptor antagonist (LTRA) administration...

Asthma is a chronic inflammatory disease, and its prevalence is relatively high among children. Optimal management of asthma often requires long-term pharmacotherapy; however, the effects of these medications on orthodontic treatment is uncertain. We evaluated the effects of the leukotriene LTD4 receptor antagonist montelukast on orthodontic tooth movement in an animal model. Eight mongrel dogs were given montelukast for periods up to 4 weeks. An orthodontic force of 150-200 g was applied to move the second and fourth premolars toward the site of the extracted third premolar...

Tyrosine kinase inhibitors targeting the BCR-ABL oncoprotein in chronic myeloid leukemia (CML) are remarkably effective inducing deep molecular remission in most patients. However, they are less effective to eradicate the leukemic stem cells (LSC), resulting in disease persistence. Therefore, there is great need to develop novel therapeutic strategies to specifically target the LSC. In an experimental mouse CML model system, the leukotriene pathway, and specifically, the expression ALOX5, encoding 5-lipoxygenase (5-LO), has been reported as a critical regulator of the LSC...

Cognitive decline and dementia are a growing problem as the population ages. Effective therapies to prevent and treat these problems are limited. Neuro-inflammation has been suggested as a cause of dementia [1]. Montelukast is a leukotriene receptor antagonist used to treat seasonal allergies and asthma. It acts as a cysteinyl leukotriene (CysLT1) receptor antagonist blocking the action of leukotrienes and decreasing inflammation [2]. Animal studies have shown that administering Montelukast improves memory function [3]...
