制备方法与用途

盐酸依普拉酮的盐酸盐是一种白色结晶粉末，无臭且味道苦涩。它能溶于热水，但在冷水中难溶，并不溶于丙酮或乙醚。这是一种兼具中枢性与末梢镇咳作用的非成瘾性镇咳药，主要通过作用于咳嗽中枢来发挥作用。

生物活性

Eprazinone（NSC 317935）是一种化痰药物。

靶点

神经激肽1受体 (NK1R)。

体外研究

Eprazinone 特异性地置换 NK1R 的结合。尽管在浓度为25 μM时，Eprazinone 对 [ ¹²⁵I]BH-SP 结合到 NK1R 上的抑制作用较弱，并表现出约30%的拮抗效应，但NK1R阻断可能有助于其化痰活性。

体内研究

作为推荐的化痰剂，Eprazinone 2HCl 具有分泌溶解和支气管解痉特性。它改善了肺功能并提升了动脉pO₂水平。此外，Eprazinone 还具有镇咳和祛痰作用，并影响支气管肺泡灌洗液 (BAL) 中的脂质水平及离子迁移。
