sodium channel blockers

Sodium channel blockers are medications that inhibit the flow of sodium ions into nerve and muscle cells through specific channels. By doing so, they slow down the electrical signals that trigger nerve impulses and muscle contractions. This action can help stabilize abnormal electrical activity, making these drugs useful for treating conditions like epilepsy, certain heart arrhythmias, and nerve pain. Essentially, sodium channel blockers reduce overexcitation of nerve cells and prevent irregular signals, helping to restore normal function in affected tissues.
