Which drug class is used to control convulsions?

• A. Anticoagulant
• B. Antianemic
• C. Antifungal
• D. Anticonvulsant

Answer: (D)

Convulsions come from abnormal, excessive electrical activity in the brain, so the goal is to dampen neuronal excitability. Anticonvulsants achieve this by stabilizing nerve membranes and boosting inhibitory signals. Many anticonvulsants enhance GABAergic transmission, which quiets neuronal firing. Others block voltage-gated sodium channels to prevent rapid, repetitive firing, or inhibit T-type calcium channels to reduce rhythmic bursts in certain seizure types. This combination directly targets the mechanisms underlying seizures, making anticonvulsants the class used to control convulsions. The other listed drug classes serve different purposes—anticoagulants prevent blood clots, antianemics treat anemia, and antifungals fight fungal infections—so they don’t address seizure activity.
