钾离子通道阻断剂（Potassium Channel Blockers），是一类可抑制K+通过膜通道的化合物，包括有机化合物和各类神经毒素（如α-Dendrotoxin，Apamin 等）
钾离子通道是四聚体的整合膜蛋白，形成水孔，K+可以通过水孔流动，并在许多生物体中发现。在神经元中，K+通道参与维持静息电位、动作电位后的膜复极、控制重复放电的时间。K+通道是生物体内广泛的离子转运分子，在人类体内有70多个基因编码不同的K+通道。
下表给大家带来三种针对不同钾离子通道的阻滞剂（Blocker）：电压门控钾离子通道抗体（Voltage-gated Ion Channel，简称Kv）、钙激活钾离子通道（Ca2+-Activated K+ Channels，简称KCa）、 内向整流型钾离子通道（Inward Rectifier K+ Channels，简称Kir）
