HOW DO POTASSIUM CHANNEL BLOCKERS WORK?
Potassium channel blockers are a class of drugs used for treating arrhythmias (improper beating of the heart, whether irregular, too fast or too slow). They also improve movement in people with multiple sclerosis.
In multiple sclerosis, the nerve cells do not have myelin sheets (demyelination). As a result, the potassium channels get exposed, leading to the leakage of potassium ions. When potassium starts to leak, there is a decrease in the nerve excitability or action potential, and the communication between the nerve and muscles does not occur. Thus, the muscles fail to work.
Potassium channel blockers inhibit the potassium channel in the central nervous system and prolong action potential. They help to improve movement in people with multiple sclerosis.
