The goal of this study is to show the capacity of this new technique to assay the active ingredient in low-dosage tablets. NIR spectroscopy is a rapid, non-destructive technique and does not need any sample preparation. A prediction model was built by using a partial least square regression fit method. The NIR assay was performed by transmission. The results obtained by NIR spectroscopy were compared with the conventional HPLC method for Montelukast tablets produced by Sigma pharmaceutical corp. The study showed that Montelukast tablets can be individually analyzed by NIR with high accuracy. It was shown that the variability of this new tech- nique is less important than that of the conventional method which is the HPLC with UV detection.展开更多
目的探讨孟鲁司特钠口溶膜与咀嚼片在过敏性鼻炎患儿中的应用效果及安全性。方法将2022年4—12月十堰市太和医院收治的80例过敏性鼻炎患儿根据随机数字表法分为两组。对照组40例患儿采用孟鲁司特钠咀嚼片进行治疗,观察组40例患儿则采用...目的探讨孟鲁司特钠口溶膜与咀嚼片在过敏性鼻炎患儿中的应用效果及安全性。方法将2022年4—12月十堰市太和医院收治的80例过敏性鼻炎患儿根据随机数字表法分为两组。对照组40例患儿采用孟鲁司特钠咀嚼片进行治疗,观察组40例患儿则采用孟鲁司特钠口溶膜进行治疗。将两组过敏性鼻炎治疗总有效率、不良情况发生率、不良反应发生率、治疗前后的变态反应指标[血清特异性IgE(serum specific IgE,SIgE)及嗜酸粒细胞阳离子蛋白(eosinophil cationic protein,ECP)]、治疗依从性(Morisky用药依从性问卷)及生存质量(少年儿童慢性鼻窦炎患者生活质量量表评分)进行比较。结果两组过敏性鼻炎治疗总有效率及不良反应总发生率比较,差异无统计学意义(P>0.05);观察组不良情况总发生率低于对照组(P<0.05);治疗前两组的变态反应指标、Morisky用药依从性及少年儿童慢性鼻窦炎患者生活质量量表评分比较,差异无统计学意义(P>0.05);治疗3周后观察组的变态反应指标低于对照组,Morisky用药依从性及少年儿童慢性鼻窦炎患者生活质量量表评分优于对照组(P<0.05)。结论鲁司特钠口溶膜在过敏性鼻炎患儿中的应用效果值得肯定,安全性更为优于咀嚼片,且患儿的治疗依从性相对更高,因此在过敏性鼻炎患儿中的应用价值较高。展开更多
