性状：
是一个非常薄的白色至黄色的粉末。是高度吸湿的，它是稍微不稳定的要轻。它是易溶水，对甲醇，微溶于乙醇(95)，溶解性，几乎在乙醚和乙酸乙酯不溶。
分配系数：
在0.95[1辛醇/pH6.8缓冲区分配系数(LogD)
药效药理：
1.对瘙痒症采取作用
抗组胺药，现有的止痒剂，抑制有效的组胺皮内给药诱导的小鼠搔抓行为和P物质皮内给药诱导的物质搔抓行为，其中抗组胺药效果较差。
抗组胺药还能抑制小鼠脑池内诱导的小鼠搔抓行为，这是一种无效的中枢瘙痒模型。
2. 作用机序
从体外受体结合试验和使用人类阿片受体表达细胞的受体激动试验的结果来看，已经显示它是一种选择性阿片样物质κ受体激动剂。
见表13“人类阿片受体结合试验和可操作性试验结果”。
此外，体外试验不结合除含有组胺受体的阿片受体以外的各种受体，转运蛋白和离子通道，也显示对来自肥大细胞的脱粒反应没有抑制作用。
另外，P物质皮内给药诱导的P物质抑制作用，通过侧脑室给药阿片κ受体拮抗剂norbinaltorphine(nor-BNI)完全拮抗。
3. 依存性
由于在大鼠戒断症状观察中在吗啡中观察到不存在戒断症状的情况下贝伐珠单抗的物理依赖性较弱，所以在猴自我接受测试中没有观察到强化作用，因此精神依赖性 它被认为不是。
