Casopitant mesylate was identified as part of the search for drugs with activity on the Central Nervous System (CNS) by GlaxoSmithKline. During late-phase development studies to develop the manufacturing process, a new impurity was found. This synthetic impurity, a defluorinated analogue of the drug substance, is discussed in detail to show the process development studies carried out to ensure quality
葛兰素史克(GlaxoSmithKline)将甲磺酸卡西波坦鉴定为对中枢神经系统(CNS)具有活性的药物的一部分。在开发制造过程的后期开发研究中,发现了新的杂质。详细讨论了这种合成杂质(一种原料药的脱氟类似物),以显示进行的工艺开发研究,以确保按照设计质量原则对最终原料药进行质量控制。通过对过程的了解以及风险分析,可以制定控制策略以提高质量保证水平。该控制策略允许将对杂质的控制移至起点,而不是在原料药中进行测试。
