Question:
Which of the following describes the mechanisms of action of antiseizure medications? Select all that apply.
Answer:
The mechanisms of action of antiseizure medications include suppression of sodium influx, suppression of calcium influx, promotion of potassium efflux, blockade of glutamate receptors, and an increase of gamma-aminobutyric acid (GABA). Antiseizure drugs are known to suppress the discharge of neurons within a seizure focus and suppress the propagation of seizure activity to other areas of the brain. Recently, it was discovered that nearly all
antiseizure drugs act through five basic mechanisms: suppression of sodium
influx, suppression of calcium influx, promotion of potassium efflux, blockade of receptors for glutamate, and potentiation or increase of gamma- aminobutyric acid (GABA).

Answer:
