Desidustat (DES) belongs to a new category of drugs, i.e., Hypoxia-Inducible Factor (HIF) propyl hydroxylase inhibitor, and is used for the treatment of anemia in chronic kidney disease. However, no method has yet been reported in the literature for the estimation of drugs.
The objective of the study is to develop a simple, precise, and accurate method for determining DES in bulk and pharmaceutical dose form.
The physicochemical characterization of the drug was performed using methanol as a solvent to establish the identity. According to ICH Q2 criteria, validation characteristics, such as specificity, linearity, accuracy, precision, limits of detection and quantification, and robustness, were assessed.
Maximum absorbance wavelength was observed at 229 nm. The sample solution remained stable for up to 12 hours. The linear response from 2 to 12 μg/ml of DES was y = 0.1087x + 0.0962 and r2 = 0.9963. The accuracy was between 100 to 101%. Precision was recorded under three criteria: repeatability, intraday and interday, for which results fell within the acceptable ranges (<2%). The limit of detection (LOD) and limit of quantification (LOQ) of the technique were 0.434 μg/ml and 1.316 μg/ml, respectively.
The proposed method was found to be beneficial for drug monitoring and the ongoing analysis of DES in research and quality control laboratories. This approach is simple, precise, rapid, economical, and sensitive.
地舒单抗(DES)属于新型药物,即低氧诱导因子(HIF)脯氨酰羟化酶抑制剂,用于治疗慢性肾脏病引起的贫血。然而,文献中尚未报道用于估计药物的方法。
本研究旨在建立一种简单、精确、准确的方法,用于测定地舒单抗原料药和制剂的含量。
采用甲醇作为溶剂进行药物的理化特性表征,以确定其身份。根据 ICH Q2 标准,评估验证特性,如专属性、线性、准确度、精密度、检测限和定量限以及稳健性。
在 229nm 处观察到最大吸收波长。样品溶液在 12 小时内保持稳定。DES 浓度为 2 至 12μg/ml 时的线性响应为 y=0.1087x+0.0962,r2=0.9963。准确度在 100%至 101%之间。精密度在三种标准下(重复性、日内和日间)进行记录,结果均在可接受范围内(<2%)。该技术的检测限(LOD)和定量限(LOQ)分别为 0.434μg/ml 和 1.316μg/ml。
该方法对于药物监测和研究和质量控制实验室中地舒单抗的持续分析具有重要意义。该方法简单、精确、快速、经济且灵敏。
