Abstract In the current study electrospraying methodology was used for particle engineering of montelukast and budesonide to prepare a combined inhalable dry powder formulation applicable as a smart regimen in asthma treatment. For this, electrospraying was carried out using different solvents and drug concentrations. No carrier was added for the formulation of montelukast-budesonide combination as montelukast played the role of both active ingredient and carrier. Scanning electron microscopy, particle size analysis, gas chromatography, powder X-ray diffraction, Fourier transform infrared spectroscopy, and differential scanning calorimetry were used to evaluate the physicochemical properties of the produced drug particles. In vitro drug deposition pattern was assessed using next generation impactor, and the dissolution profile of the selected formulations was characterized via modified diffusion franz cell method. The FPF value for the co-electrosprayed carrier free formulation of montelukast-budesonide was 38% with a significantly enhanced dissolution rate for budesonide compared to the budesonide alone formulations. The pharmacological effects of hypothesized combined formulation was assessed by measuring its power to inhibit the production of reactive oxygen species in human normal lung cells. The results showed that the combination of montelukast and budesonide can exert a synergistic effect. The findings in the current study emphasize that using montelukast as a carrier for budesonide not only has greatly improved the aerosolization behavior and dissolution rate of budesonide but also has resulted in synergistic pharmacological effects, indicating the suitability of this combination as an anti-asthmatic therapeutic.

Abstract Montelukast is used as alternative treatment for asthma. However, some adverse drug reactions have been reported for the oral dosage form of montelukast. To counter this issue, the drug was formulated into a pressurized metered-dose inhaler (pMDI), which delivered montelukast directly to the lower regions of the lungs. Montelukast sodium, mixed with either HFA 134a propellant or a mixed propellant (HFA-134a and HFA227), was formulated into a pMDI with other excipients. The canister was ...

Abstract In this work, montelukast (MTK) was incorporated in inhalable soft agglomerates (SA) exhibiting inherent characteristics for deep lung deposition while expressing good flowability and enhanced shelf-life stability. Mannitol and ovalbumin were used as particle shapers and lecithin as binder during microparticles (MPs) preparation by spray drying. The spontaneously agglomerated MPs with an adhesive surface were designed to deagglomerate under the effect of aerosolization with selected dry...
Asthma in elderly patients causes excessive suffering and inconvenience. Regimens with better efficacy and less adverse events are still in need of researches. To investigate the effect of montelukast sodium plus budesonide on lung function, inflammatory factors, and immune levels in elderly asthma patients. A total of 180 patients with asthma were assigned into the control group and the observation group. The control group was given aerosol inhalation of budesonide suspension, while the observa...

Abstract Also known as electrospray, electrohydrodynamic atomization has been used extensively in the last 15鈥痽ears to develop polymer-based particles for drug delivery in cell and animal models. More recently, novel core-shell, multi-axial, and other electrospray particles have been developed from an array of polymers for a variety of biomedical applications. This review focuses on electrospray as a novel method of particle fabrication for drug delivery, specifically highlighting the applicatio...
The aim of this study was to explore the clinical effect of montelukast sodium chewable tablets combined with inhaled budesonide in the treatment of pediatric asthma and its influence on inflammatory factors. One hundred and thirty-five asthmatic children were randomly divided into montelukast sodium group, budesonide group and combined group. Clinical symptoms, lung function, inflammatory factors and immune related indices of patients in each group were observed and recorded. After treatment, t...

Abstract Spray drying is a well-established technology to produce inhalable dry powders. However, the amorphous nature of the particles typically obtained from the process can lead to physically and chemically unstable products. The purpose of this study was to investigate whether spray-drying could be used as a manufacturing method to produce co-amorphous drug amino acid powders with high physical stability and inhalable particulate properties. Budesonide (BUD), a compound for the treatment of ...

Abstract Dry powder inhalers (DPI) are widely used systems for pulmonary delivery of therapeutics. The inhalation performance of DPIs is influenced by formulation features, inhaler device and inhalation pattern. The current review presents the affecting factors with great focus on powder characteristics which include particle size, shape, surface, density, hygroscopicity and crystallinity. The properties of a formulation are greatly influenced by a number of physicochemical factors of drug and a...
