Rising number of the nonresponding dermatophytic infections raises deep concerns among the dermatologists across the nation. Variations in the quality of itraconazole may be a contributing factor to nonresponse in certain dermatophytic infections. This article will address this issue in a simple way of analyzing things in an OPD and may help us in being aware and taking the right foot forward.
To assess the quality of itraconazole brands by observing the morphological properties of pellets/beads in different brands.
In this study, 10 brands of itraconazole that are commonly used in clinical practice were randomly selected. Pellet counts and qualitative morphological analysis of pellets as size (small, large, or mixed), shape (uniform or nonuniform), and presence of amorphous material was performed by three independent observers. Also, dissolution profile of some brands was assessed by adding the pellets in equal quantity of water.
The pellet counts of brands varied from 856 pellets per capsule in brand 1 to 109 pellets per capsule in brand 8. Brand 1, brand 2, and brand 7 pellets were small and uniform in morphology. Brand 3, brand 4, and brand 10 pellets were mixed in size but uniform in morphology. Brand 9 pellets were mixed and nonuniform whereas brand 5, brand 6, and brand 8 pellets were mixed in size, nonuniform in shape, and had presence of amorphous material. Dissolution test revealed that brand 5 dissolved rapidly and turned clear water color to milky white.
A simple dermoscopy examination of itraconazole pellets may provide thoughtful insights about the quality of itraconazole brand. It may be considered as routine practice for all dermatophytic infection planned for treatment with itraconazole.
无反应性皮肤癣菌感染病例数量不断增加,引起了全国皮肤科医生的深切关注。伊曲康唑质量的差异可能是某些皮肤癣菌感染无反应的一个促成因素。本文将以一种简单的方式在门诊分析此事,可能有助于我们提高认识并迈出正确的第一步。
通过观察不同品牌药丸/微丸的形态学特性来评估伊曲康唑品牌的质量。
在本研究中,随机选择了临床实践中常用的10个伊曲康唑品牌。由三名独立观察者对药丸进行计数,并对药丸的大小(小、大或混合)、形状(均匀或不均匀)和无定形物质的存在进行定性形态分析。此外,通过将等量药丸加入水中来评估一些品牌的溶出曲线。
各品牌药丸计数从品牌1的每粒胶囊856丸到品牌8的每粒胶囊109丸不等。品牌1、品牌2和品牌7的药丸小且形态均匀。品牌3、品牌4和品牌10的药丸大小混合但形态均匀。品牌9的药丸大小混合且不均匀,而品牌5、品牌6和品牌8的药丸大小混合、形状不均匀且有无定形物质。溶出试验表明,品牌5溶解迅速,使清澈的水颜色变为乳白色。
对伊曲康唑药丸进行简单的皮肤镜检查可能会提供有关伊曲康唑品牌质量的深刻见解。对于所有计划用伊曲康唑治疗的皮肤癣菌感染,可将其视为常规做法。
