BACKGROUND Inhaled corticosteroids (ICS) affect many inflammatory pathways in asthma but have little impact on cysteinyl leukotrienes. This may partly explain persistent airway inflammation during chronic ICS treatment and failure to achieve adequate asthma control in some patients. This double blind, randomised, parallel group, non-inferiority, multicentre 16 week study compared the clinical b...
BACKGROUND Montelukast is a leukotriene receptor antagonist for treatment of asthma, gliclazide is an oral hypoglycemic antidiabetic agent, and nifedipine is a calcium channel blocker used for treatment of angina pectoris and hypertension. These drugs may be prescribed to patients suffering from these chronic diseases. A survey of the literature reveals that there is no reported method for the ...
BACKGROUND Exercise induced bronchoconstriction (EIB) is common in elite athletes. Eucapnic voluntary hyperventilation (EVH) is a laboratory test recommended for the identification of EIB in athletes, secondary to a field exercise challenge. Montelukast attenuates EIB, but its protective effect against airway narrowing from EVH has not been investigated. OBJECTIVE To examine the effectiveness...
OBJECTIVES/HYPOTHESIS The aim of this study was to investigate the serum levels of montelukast when administered alone or in combination with desloratadine. STUDY DESIGN A prospective crossover study. METHODS Twenty-three healthy volunteers were investigated in two sessions. Volunteers were given 10 mg of montelukast orally with 250 mL water in the first session. The same subjects were give...
The Arg(16) β(2) receptor genotype confers increased susceptibility to exacerbations in asthmatic children taking regular LABA (long-acting β(2) agonists). We therefore evaluated using montelukast as an alternative to salmeterol as tailored second-line asthma controller therapy in children expressing this susceptible genotype. A total of 62 persistent asthmatic children with the homozygous Arg1...
Montelukast sodium is a leukotriene inhibitor, and competitively antagonizes cys-LT1 receptor and used widely and effectively in treating allergic rhinitis, bronchial asthma and allied respiratory conditions. This case report outlines a rare case of montelukast induced hypercholesterolemia, severe hypertriglyceridemia and acute pancreatitis in a 22 years old male patient. The patient was taking...
Sputum eosinophilia is a sensitive predictor of benefit from corticosteroid treatment. Montelukast is a cysteinyl leukotriene antagonist, which also reduces sputum and blood eosinophils. The present study examined the possibility that montelukast has an added eosinophil-lowering effect in subjects with asthma who are corticosteroid responsive but relatively corticosteroid resistant. A total of ...
Montelukast (L-706,631, MK-0476, SINGULAIR), a potent and selective leukotriene D4 (CysLT1) receptor antagonist, is currently under development for the treatment of asthma. In vitro studies were conducted using human liver microsomes to evaluate: 1) the difference in the metabolic kinetics of montelukast between adult and pediatric subjects; 2) the relative contribution of flavin-containing mon...
The leukotrienes and prostaglandins are biologically active metabolites derived from arachidonic acid. The leukotrienes have a role in inflammatory diseases such as allergic rhinitis, inflammatory bowel disease and asthma. Montelukast, a cysteinyl leukotriene receptor antagonist, is claimed to be effective in asthma. The present study aimed to assess the role of cysteinyl leukotriene receptor a...
Montelukast is a selective and competitive cysteinyl leukotriene receptor antagonist (CystLTRA) which is increasingly used for the treatment of allergic asthma. Recently, hepatotoxicity has been reported with this drug in adult patients, but only one letter to the editor has reported a case of probable montelukast-induced hepatotoxicity in a child. We present a case of a 3.5-year-old boy, recei...
