ABSTRACT
Objective To explore the effect of budesonide suspension for inhalation in the treatment of childhood asthma and its influence on growth and development in 1-2 years. Methods The 68 children with asthma admitted to our hospital from October 2016 to January 2017 were selected. Every patient had acute attacks and received continued medication. 34 patients treated with salbutamol sulfate inhaled aerosol were used as the control group. 34 patients treated with budesonide suspension combined with salbutamol sulfate aerosol were classified as the observation group. The interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α), high-sensitivity-C-reactive protein (hs-CRP), maximum respiratory flow, IS maximum expiratory volume, regulatory B cell ratio, wheezing disappearance time, shortness of breath relief time, wet rales disappearing time, cough disappearing time, and the two year follow-up indicators of growth and development were compared. Results After medication, IL-6, TNF-α, hs-CRP, regulatory B cell ratio, wheezing disappearance time, shortness of breath relief time, moist rales disappearance time, and cough disappearance time were lower in the observation group(P<0.05). The maximum respiratory flow and IS maximum expiratory volume in the observation group were higher than those in the control group (P<0.05). The GH level, height, and weight obtained from two year follow up in the observation group were lower than those in the control group (P<0.05). Conclusion Budesonide suspension combined with salbutamol sulfate aerosol inhalation therapy can alleviate the inflammatory reaction, improve the lung function and immune function of children, and accelerate the disappearance of clinical symptoms, but it will affect the growth and development of children to a certain extent.

ABSTRACT
Objective To assess the clinical efficacy of budesonide in combination with salbutamol sulfate and ambroxol through fog inhalation in the treatment of elderly patients older than 70 years with acute exacerbation chronic obstructive pneumonia disease (AECOPD). Methods A total of 58 elderly patients older than 70 years with AECOPD were randomly assigned to receive medication of budesonide in combination with salbutamol sulfate and ambroxol through fog inhalation in addition to conventional therapy ( n = 58 treatment group). In the control group,56 AECOPD patients received conventional therapy (including oxygen uptaking,anti-infection, medication, relieving asthma, eliminating sputum, nutritional support, et al). Results The overall effective rate in the treatment group was 76.79% (43/56) ,which was significantly lower than that in the control group 89. 66% (52/58) ( χ2 = 6. 46, P = 0. 007 ). Blood gas analysis ( pH, PaCO2, PaO2 ) and lung function ( FEV1/FVC, FEV1 occupy prospect% ) outcome were significantly improved after treatment (Ps ＜ 0.05 ). We found no significant difference in the comparison of the blood gas analysis improvement between the treatment and control ( Ps ＞ 0. 05 ), whereas significant difference was observed in the improvement on lung function between the two groups (P ＜ 0. 05 ). Conclusion Combined budesonide with salbutamol sulfate and ambroxol through fog inhalation in addition to conventional therapy has a significant better effect and less side effects on the treatment of AECOPD patients older than 70 years.
ABSTRACT
Aim: To study the hydrofluoroalkane-driven(HFA-134a) salbutamol sulfate (SS) MDI formulation compositions and the respiratory tract absorption in rats. Methods: Solubility determination and orthogonal design were used to aid the screening of non-CFC SS MDI formulations. Rats were exposed to SS MDI via intubation inhalation. Fluorescent HPLC detection was developed to determine plasma SS concentration in rats given the selected SS MDI formulations. Analysis of the plasma drug level-time profiles was performed by the statistical moment approach. Results: Stable and homogeneous non-CFC SS MDI formulations were obtained. The developed HPLC method was validated and used to assay SS levels in the rats after inhalation of the MDI. AUC ratios of the SS/HFA-134a-driven MDI formulation to the reference SS MDI and CFC SS MDI formulation were 109. 86% and 135. 54%, respectively. Conclusion: It is proven that the absorption of the HFA-134a SS MDI formulation in rats is equivalent to the simulant formulation commercially available oversea and better than CFC formulation.
