Potassium channel inhibitors are pharmaceutical agents that influence the flow of potassium ions across cell membranes. By targeting these channels, they modify the cell's excitability, often in a manner that reduces excessive nerve or muscle activity. This class of drugs is used to manage conditions like arrhythmias, epilepsy, and neuropathic pain. They work by stabilizing cell membranes and preventing abnormal electrical impulses, making them valuable tools in maintaining heart rhythm and alleviating neurological disorders.
