PC98037
含大黄酸的治疗糖尿病肾病的药 技术领域 本发明涉及一种葸醌的羧酸, 具体地说是含大黄酸的治疗糖尿病肾病 的药。 背景技术 糖尿病是一种多发病, 目前治疗糖尿病的药物主要是胰岛素。 胰岛素 虽然能降低尿糖, 但对糖尿病引起的肾损害如肾肥大, 则无治疗效果。 目 前尚未见有治疗糖尿病引起的肾肥大的药物的报导。 发明内容 本发明的目的在于提供一种低毒的能治疗糖尿病肾病的药。
本发明的技术方案是, 将大黄酸或大黄酸盐制成治疗糖尿病肾病的口 服液。
大黄酸是我国特产的药物, 是中医最常用的中药之一, 大黄酸有如下 化学结构:
Figure imgf000003_0001
是大黄所含的化学成份之一, 它是一种天然产物, 因此毒性小。 经大 鼠急性毒性实验结果表明, 大黄酸的半数致死量 ( LD5。) 为 3. 2g/kg。
经人体实验结果表明, 大黄酸无明显的胃肠道反应。 当口服大黄酸用 药剂量为 200mg/日 ( lOOmg/次, 每日二次) 时, 连续服药三日, 36人中 只有 5人次有胃肠道不适主诉, 其中 3人每日腹泻 2-3次, 仅 1人腹泻超 过 4次。
药物代谢研究结果表明, 大黄酸易被人体吸收, 服药后血药浓度维持 时间较长。 单次口服 200mg大黄酸 1. 5-3小时后, 血中大黄酸的浓度达到 高峰, 24小时后其血药浓度仍保持在 200- 500ng/ml水平。 因此大黄酸作为药物有其优越性。
进一步研究表明, 口服大黄酸或大黄酸钠盐能有效地控制或降低糖尿 病大鼠的血糖量, 特别是能控制或减轻肾脏肥大的症状, 能明显地降低肾 脏指数, 降低糖尿病患者尿白蛋白的排泄量。
含大黄酸 (或其盐) 的治疗糖尿病肾病的药可以是含大黄酸 (或其盐) 的口服胶囊或是口服的的大黄酸 (或其盐) 水溶液。
口服大黄酸的剂量是不大于 200mg/日为宜, 可以分成 2次口服或 3次 口服。 实施发明的最佳方式 实施例 1 口服大黄酸抑制糖尿病大鼠肾脏肥大的作用
