RESUMO

(1) Background: It is common practice in the treatment of respiratory diseases to mix different inhalation solutions for simultaneous inhalation. At present, a small number of studies have been published that evaluate the physicochemical compatibility and aerosol characteristics of different inhalation medications. However, none of them studied Atrovent®. Our work aims to address the lack of studies on Atrovent®. (2) Methods: Portions of admixtures were withdrawn at certain time intervals after mixing and were tested by pH determination, osmolarity measurement, and high-performance liquid chromatography (HPLC) assay of each active ingredient as measures of physicochemical compatibility. The geometrical and aerosol particle size distribution, active drug delivery rate, and total active drug delivered were measured to characterize aerosol behaviors. (3) Results: During the testing time, no significant variation was found in the pH value, the osmotic pressure, or the active components of admixtures. With the increase in nebulization volume after mixing, fine particle dose (FPD) and total active drug delivered showed statistically significant improvements, while the active drug delivery rate decreased compared to the single-drug preparations. (4) Conclusions: These results endorse the physicochemical compatibility of Atrovent® over 1 h when mixed with other inhalation medications. Considering aerosol characteristics, simultaneous inhalation is more efficient.

RESUMO

INTRODUCTION: Spacers offer a multitude of benefits by reducing the requirement to coordinate inhalation with actuation and improving inhaler technique in patients using a pressurized metered dose inhaler (pMDI). Spacers improve drug targeting by retaining within the spacer large particles normally deposited in the oropharynx, and by creating a prolonged aerosol cloud of fine particles to give the user increased time to inhale after actuation. This is particularly important in young children and the elderly to effectively deliver medication to the airways. AREAS COVERED: By investigating the history and features of spacers, we demonstrate that the advantages of using spacers far outweigh their limitations. We also discuss the optimal characteristics of spacers in terms of shape, volume, presence of valve and static charge, and present a detailed discussion of the VENTOLIN™ Mini Spacer. EXPERT OPINION: Generally, the shape and size of spacers makes them inherently inconvenient. Consideration of human factors and modern design may make them more attractive to patients. However, the incentive to use spacers should be their ability to help patients correctly use inhaled medications delivered by pMDIs. Understanding of these principles through education is key to their acceptance by patients.

RESUMO

INTRODUCTION: ß2-agonists are first election drugs for the treatment of respiratory disease that may alter cardiac autonomic modulation. The aim of this study was to evaluate the effects of nebulized Ventolin on electrocardiogram, particularly QTc interval to assess the potential arrhythmogenic risks. METHODS: A total of 192 patients between 2 months and 15 years which received nebulized Ventolin were enrolled in this study. Patients were divided into two groups. Electrocardiograms of patients before and after nebulized Ventolin were taken. Differences between two groups were assessed using a paired student's t test. RESULTS: There was statistically significant differences in QTc before and after Ventolin in each groups (P<0.005).Ventolin effect on QTc interval in both groups did not differ. In first group, there was statistically significant differences between heart rate before and after Ventolin taken (P=0.009) but in second group there was not statistically significant differences between heart rate (P=0.345). CONCLUSION: Although Ventolin can cause changes in QTc, Ventolin with 0.15 mg/kg/dose in comparison with 0.1 mg/kg/dose does not cause significant changes in QTc.

RESUMO

BACKGROUND: Complications of Ventolin as the most common drug used for bronchiolitis are widely known. The present study was conducted to determine the efficacy of hypertonic saline 3%, compared with Ventolin, for treatment of acute bronchiolitis in children. METHODS: This double-blinded clinical trial study was conducted in Hajar Hospital, Shahrekord, Iran, from 2011 to 2012. A total of 70 patients under the age of two years with bronchiolitis were divided into two groups of 35 each. Ventolin nebulizer and hypertonic saline 3% nebulizer three times per day were administered in the first (Ventolin) and second (Hypersaline) group, respectively. The length of recovery was compared between the two groups. The data were analyzed by SPSS software (version 22) using chi-square, t-test, paired t-test, and Mann-Whitney. RESULTS: The mean±SD length of recovery was 4.14±0.9 and 3.06±0.6 in the Ventolin and hypersaline groups, respectively. The mean duration of recovery was significantly lower in the hypersaline group (p<0.001). CONCLUSION: Hypertonic saline 3% nebulizer has more pleasant therapeutic effects on acute bronchiolitis than Ventolin. Therefore, use of hypertonic saline 3% nebulizer is recommended for the treatment of acute bronchiolitis in children under two years old.

RESUMO

The performance of pressurized metered-dose inhalers (pMDIs) under a variety of temperature conditions was investigated. The effects of both inhaler temperature and ambient temperature were considered. The inhaler temperature ranged from -13.0°C to 41.7°C and the ambient temperature ranged from -12.0°C to 41.7°C. The in vitro lung dose was measured for four widely available pMDIs: Airomir(TM) , QVAR(TM) , Symbicort(®) , and Ventolin(®) . The in vitro lung dose through an Alberta Idealized Throat was measured by gravimetric assay, which was verified by UV spectroscopic assay. A decrease in the in vitro lung dose was observed for all evaluated pMDIs when ambient temperature and device temperature were simultaneously reduced, decreasing on average by 70% at the coldest temperatures, whereas increasing on average by 25% at the elevated temperature condition. In vitro lung dose is strongly dependent on both inhaler temperature and ambient temperature with the tested pMDIs.

RESUMO

OBJECTIVE:To evaluate the therapeutic efficacy of oxygen-driven aerosol inhalation of Ventolin plus Atrovent and Budesonide suspension for acute episode of intermediate or severe degree of bronchial asthma. METHODS:A total of 48 patients with bronchial asthma were divided into two groups randomly:26 cases in the treatment group received normal saline (1 mL) +Ventolin (2 mL) + Atrovent (2 mL) and Budesonide suspension(4 mL) q6 h in addition to the routinetherapy by high-flow oxygen driven in addition to the routine therapy; 22 cases in the control group received Ventolin inhaler(200 ?g) q 6 h. The improvement of clinical symptoms in the two groups after treatment for 3 days,the forced expiratory volume in one second (FEV1),forced vital capacity (FVC),peak expiratory flow (PEF) at 3 h and 5 days,respectively,the blood sugar level,arterial blood gas index as well as duration of systemic use of hormone and the hospital days were compared between two groups. RESULTS:After treatment for 3 days,the effective rate in the treatment group(24/26) was significantly higher than in the control group (14/22),showing significant differences between two groups. At 3 h,there were significant differences between the treatment group and the control group in FEV1 and PEF but not in FVC; at 5 days,there were significant differences between the treatment group and the control group in FEV1,FVC and PEF. On day 5,there were significant differences between two groups in PaO2,PaCO2 and blood sugar level as well as in the duration of systemic use of hormone and the hospital days. CONCLUSION:Aerosol inhalation of Ventolin plus Atrovent and Budesonide suspension shows remarkable therapeutic efficacy for acute episode of intermediate or severe degree of bronchial asthma.
