Leukotrienes are pro-inflammatory mediators which may contribute to tissue, sputum, and blood eosinophilia seen in allergic and inflammatory diseases, including asthma. Montelukast is a cysteinyl leukotriene1 (CysLT1) receptor antagonist which improves asthma control; the aim of this study was to investigate its effect on induced sputum eosinophils. Montelukast 10 mg (n=19) or placebo (n=21) we...

BACKGROUND Experimental clinical studies have demonstrated that the addition of salmeterol to inhaled corticosteroids (ICSs) is superior to the addition of montelukast to ICSs. Observational research from real-world clinical practice is needed to confirm these results. OBJECTIVE The present study was designed to assess, in clinical practice, the comparative impact on health care utilization a...

OBJECTIVE To assess the utilization of leukotriene modifiers (LM) relative to national guidelines and to investigate possible emergency room utilization differences for LMs as monotherapy versus inhaled corticosteroid (ICS) monotherapy or combination ICS and LM therapy. METHODS The utilization of leukotriene modifiers (montelukast sodium, zafirlukast, and zileuton), concurrent inhaled steroid...

We examined the effects of two over-the-counter H1-antihistamines on the progression of fatty liver disease in male C57Bl/6 wild-type and apolipoprotein E (ApoE)-/- mice. Mice were fed a high-fat diet (HFD) for 3 mo, together with administration of either cetirizine (4 mg/kg body wt) or fexofenadine (40 mg/kg body wt) in drinking water. Antihistamine treatments increased body weight gain, gonad...

The presented article presents results analysis effectiveness, safety impact on quality life patients, use singular, in various forms associated comorbid conditions. Aim study To assess effectiveness montelukast complex therapy patients diseases. Materials ...

Abstract Background/Aims Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare, multisystemic, autoimmune vasculitis involving small to medium-sized blood vessels. It has well-established affiliation atopic syndromes, typically adult-onset asthma and sinusitis. More rare associations are linked drug side effects such as Montelukast. According the ‘American College of Rheumatology 1990’...

H1-antihistamines, the mainstay of treatment for urticaria, were developed from anticholinergic drugs more than 70 years ago. They act as inverse agonists rather than antagonists of histamine H1-receptors which are members of the G-protein family. The older first generation H1-antihistamines penetrate readily into the brain to cause sedation, drowsiness, fatigue and impaired concentration and m...

A simple, precise and low cost conductometric method for the determination of alfuzosin hydrochloride and fexofenadine hydrochloride in pure form and pharmaceutical formulations using sodium tetraphenylborate has been described. The method is based on the formation of ion association complex of cations coming from the cited drugs with tetraphenylborate anions and the conductance of the solution...

Fixed drug eruption is an uncommon adverse drug reaction caused by delayed cell-mediated hypersensitivity. Levocetirizine is an active (R)-enatiomer of cetirizine and there have been a few reports of fixed drug eruption related to these antihistamines. We experienced a case of levocetirizine-induced fixed drug eruption and cross-reaction with other piperazine derivatives confirmed by patch test...
