Osimertinib is an oral kinase inhibitor. The molecular formula of osimertinib mesylate is c 28h 33n 7o 2 ch 4o 3s, and the molecular weight is 596 g/mol. The chemical name is N-(2-{ 2-二甲氨基乙基-甲基氨基}-4-甲氧基-5-{【4-（1-甲基吲哚-3-基）嘧啶-2-基】氨基}苯基）丙-2-烯酰胺甲磺酸盐。 奥希替尼片剂含有40或80毫克的奥西美替尼，分别相当于47.7和95.4毫克的甲磺酸奥西美替尼。 The inactive ingredients in the tablet core are mannitol, microcrystalline cellulose, low-substituted hydroxypropyl cellulose, and sodium stearyl fumarate.片剂包衣由聚乙烯醇、二氧化钛、聚乙二醇3350、滑石粉、氧化铁黄、氧化铁红和氧化铁黑组成。

The main metabolic pathways of osimertinib are oxidation (mainly CYP3A) and dealkylation in vitro. After oral administration of osimertinib, two pharmacologically active metabolites (AZ7550 and AZ5104) were found in plasma. The geometric mean exposure (AUC) for each metabolite (AZ5104 and AZ7550) was approximately 10% of the osimertinib exposure at steady state. Generic medicines cost several hundred yuan per box, and prices vary depending on the version.
