Fexofenadine hydrochloride is an antihistamine agent used for the treatment of allergic disorders like rhinitis. It is a second generation antihistamine. Montelukast sodium is an anti-asthmatic agent and leukotriene receptor antagonist used in the treatment of respiratory disorders. This article exemplifies the reported analytical methods like electrometric methods, ultraviolet spectroscopy, mass spectroscopy, thin layer chromatography, high performance liquid chromatography, high performance thin layer chromatography and tandem spectroscopy for determination of fexofenadine HCl and montelukast sodium in dosage form and in biological matrices. This review covers almost all the analytical methods for fexofenadine hydrochloride and montelukast sodium form 1968-2018 years. Complete analytical validation parameters reported are discussed in this review for both analytes. Among various analytical methods, HPLC and UV-visible spectrophotometry were found to be the most extensively used methods by the researchers.

Montelukast, a leukotriene receptor antagonist (LTRA) approved for the treatment of asthma and allergic rhinitis, is widely used, though real-world data on its application in asthma management remain limited. This registry-based study evaluated the use of montelukast in adult asthma patients, examining demographic and disease characteristics, asthma control status, asthma phenotypes, presence of atopy, and treatment regimens. Among 2053 patients analyzed, 61.

Background: Evaluation of primary care allows for identification of problems in the healthcare system, such as poor health outcomes, inappropriate health services, overuse of unnecessary resources, or underuse of recommended strategies. Assessment of adherence to existing clinical practice guidelines as quality indicators is critical for evaluating the effectiveness of primary care and shaping healthcare policies.
Objectives: To determine the adherence of primary care providers to existing practice guidelines for common pediatric concerns in remote, rural, and urban areas in the Philippines.
Inhibition of leukotrienes and their potential role in type 1 diabetes pathogenesis: implications for montelukast as a therapeutic agent: a case report.

Introduction: Type 1 diabetes involves immune-mediated destruction of insulin-producing beta cells, with eosinophils potentially playing a significant role. Recent studies suggest that leukotriene inhibition might influence this process. This case report presents a novel observation of montelukast, a leukotriene receptor antagonist, reducing insulin requirements in a patient with Latent Autoimmune Diabetes in Adults (LADA).

Cysteinyl leukotrienes (LTs) and their receptors are involved in the pathogenesis of abdominal aortic aneurysms (AAAs). However, whether CysLT1 receptor antagonists such as montelukast can influence experimental nondissecting AAA remains unclear. Nondissecting AAAs were induced in C57BL/6J mice by transient aortic luminal infusion of porcine pancreatic elastase (PPE).

This study analysed the influence of montelukast (MON), a cysteinyl leukotriene receptor antagonist, and nifedipine, an L-type voltage-gated Ca2+ channel blocker, on the contractility of the porcine uterine smooth muscle. Myometrial strips were collected from the sexually immature (n=8), cyclic (12-14 days of the oestrous cycle; n=8) and pregnant (27-28 days of pregnancy; n=8) gilts and stimulated with a) MON or nifedipine at concentrations of 10-8-10-4 M and b) increasing concentrations of nifedipine after previous administration of MON at a concentration of 10-4 M. The changes in the tension, amplitude and frequency of contractions were determined with the Hugo Sachs Elektronik equipment for measuring isometric contractions.
