Some anticonvulsants are used parenterally in the immediate treatment of seizures. Some drugs work by enhancing the effects of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA), which plays a role in regulating neuron excitability in the brain. LIFESPAN CONSIDERATIONS. The patient states, “I have never had a seizure. Second, they limit the spread of a seizure discharge from its origin by suppressing the transmission of impulses from one nerve to the next. It is not uncommon for patients to require more than one anticonvulsant to control seizures on a long-term basis. Lilley, L., Collins, S., & Snyder, J.
