WebSodium Channel Pharmacology. Sodium channels are the molecular targets for drugs used in prevention of acute pain in dentistry and surgery and in treatment of cardiac arrhythmias, epilepsy, and the manic phase of bipolar disorder. Sodium channel-blocking drugs are also in development for treatment of chronic pain. WebSodium channel blockers are anti-epileptic drugs that work in the sodium channel to preferentially affect the sodium channel at a specific stage of its cycle of rest, activation and inactivation, often by delaying the recovery from the inactivated state, thereby producing a cumulative reduction of Na +. Non-epileptic brains have a natural ...
