Which agent is described as having anticonvulsant properties?

• A. Propofol
• B. Ketamine
• C. Alpha 2 agonist
• D. Telazol

Answer: (A)

Propofol stands out for its anticonvulsant action because it strongly enhances GABAergic inhibition in the brain. By potentiating GABA_A receptor activity, it increases chloride entry into neurons, causing hyperpolarization and dampening of neuronal firing. This makes propofol effective at terminating seizures and is why it’s used in refractory status epilepticus and seizure control during anesthesia. It also reduces cerebral metabolic demand and cerebral blood flow, which helps stabilize neural activity during ongoing seizures.

Among the other options, ketamine can increase CNS excitation in some contexts and is not used for anticonvulsant purposes. An alpha-2 agonist provides mainly sedation and analgesia with limited anticonvulsant effect. Telazol includes zolazepam, a benzodiazepine, which is anticonvulsant, but the most consistently recognized anticonvulsant agent in this set is propofol.
