Which of the following is used to manage or prevent seizures?

• A. Warfarin
• B. Phenytoin (Dilantin)
• C. Metformin
• D. Albuterol

Answer: (B)

Phenytoin, commonly known by its brand name Dilantin, is an antiepileptic medication specifically used to manage and prevent seizures, particularly tonic-clonic and partial seizures. It works by stabilizing the neuronal membrane and reducing the excitability of neurons, effectively preventing the rapid firing that causes seizure activity.

This mechanism of action is critical in the management of epilepsy and seizure disorders, making phenytoin a first-line treatment option in many cases. The other medications listed serve different therapeutic purposes: Warfarin is an anticoagulant, primarily used to prevent blood clots; Metformin is an oral hypoglycemic agent used in the management of type 2 diabetes; and Albuterol is a bronchodilator typically used to treat asthma and other conditions related to airway constriction. None of these medications play a role in seizure management or prevention.
