熊去氧胆酸 （英語： Ursodeoxycholic acid，也被称为 3α,7β-二羟基-5β-胆烷-24-羧酸，3α,7β-dihydroxy-5β-cholan-24-oic acid， 缩写 UDCA），是一种来自 熊膽 的 胆汁酸 [1]，为次级胆汁酸，在大部分动物体内由初级胆汁酸经由 细菌 代谢生成。 熊科 动物可以直接合成这种胆汁酸。 [2] 提纯的熊去氧胆酸在医学上用来溶解 胆结石 、 胆泥 （英语：biliary sludge），作用机理是增加胆汁内 胆固醇 的溶解度。 [3][4] 对于 原发性胆汁性胆管炎 、 [5] 原发性硬化性胆管炎 、 [6] 妊 …

熊脱氧胆酸 (ursodeoxycholic acid，UDCA)：它是双羟基胆汁酸，亲水性，在急性和慢性肝炎的应用正在扩大。 胆盐促使水份、卵磷脂、胆固醇和结合胆红素从胆道排泄，熊脱氧胆酸盐比其它胆酸盐有大得多的利胆作用。 胆盐肠—肝循环障碍，在淤胆的病理发生中是重要的，可能与淤胆时的皮肤瘙痒有关。 口服熊脱氧胆酸后干扰胆酸和鹅脱氧胆酸在小肠的吸收，从而降低血液中的胆盐。

2020年11月19日 · 1927年，一位日本科学家从熊胆汁中成功分离出纯净的熊去氧胆酸晶体，并将其命名为ursodeoxycholicacid，“urso”在拉丁语中即表示“熊”的意思，简称UDCA。 1936年，UDCA的化学结构被确定。 1954年，科学家建立了高效合成UDCA的方法。 二十世纪七十年代后期，人们发现大剂量服用UDCA可以溶解胆固醇结石，由于UDCA肝毒性较低，于是迅速取代了先前被发现也具有同样作用但肝毒性较大的鹅去氧胆酸，从此UDCA的药用价值被西方国家认可 …
