Abstract

The objective of this study is to investigate the efficacy of nebulized Furosemide in children administered singly or combined with β-Cyclodextrins on asthma exacerbations. A blind randomized controlled experiment involving five groups of children with moderate attack of asthma. Twenty children were enrolled in each group, group 1 received nebulized Salbutamol, group 2 received nebulized Furosemide, group 3 received both Salbutamol and Furosemide, group 4 received a mixture of Furosemide/β-CD in a (1:0.5) molar ratio and group 5 received a mixture of Furosemide/β-CD in a (1:1) molar ratio. Pulmonary function parameters, peak flow rates, respiratory rate, oxygen saturation and clinical scores were obtained before and after treatment The study showed improvement in the primary outcome FEVl after drug administration in all five groups of patients. Complex of both Furosemide and Cyclodextrins led to a significant increase in peak flow rate and significantly improved of FEV1, FVC, respiratory rate, SaO2 and clinical scores as compared to other groups. The complex effect was nearly equal to Furosemide and Salbutamol combination. These results support the fact that Cyclodextrins are promising approach for improving efficacy of poorly water-soluble drugs administered by inhalation.
