Pharmacology

Phenytoin works as an anticonvulsant by promoting sodium ion efflux and limiting sodium ion influx across cell membranes in the motor cortex during nerve impulse generation. This stabilises neuronal membranes and reduces seizure activity. It also has antiarrhythmic effects, prolonging the effective refractory period, suppressing automaticity in the ventricular pacemaker, and shortening the heart's action potential.
