A. Intramuscular Phenobarbital: While effective as an anticonvulsant, phenobarbital has a slower onset of action and is not the preferred first-line treatment for acute seizures. It is more commonly used in refractory cases or for long-term seizure control.
B. Intravenous Lorazepam: Lorazepam is a benzodiazepine and the first-line treatment for active seizures, especially status epilepticus. Given IV, it acts quickly by enhancing GABA activity, which calms neuronal excitability and stops seizure activity efficiently.
C. Oral Phenytoin: Phenytoin is used for long-term seizure prevention but is not effective for terminating ongoing seizures due to its slow onset when taken orally. It may be used after benzodiazepines to prevent seizure recurrence but not as the initial agent.
D. Subcutaneous Sumatriptan: Sumatriptan is used for treating acute migraines and has no role in managing seizures. It acts on serotonin receptors to relieve migraine symptoms, not to control abnormal neuronal discharges.

• Subcutaneous: A parenteral route where medication is injected into the tissue layer between the skin and muscle. It bypasses the gastrointestinal (GI) tract, allowing for faster absorption of certain medications like insulin or heparin.
• NG Tube: A form of enteral administration that delivers medication directly into the stomach via a nasogastric tube. This route utilizes the GI tract and is often used for patients who cannot swallow.
• Oral: A classic enteral route involving medication taken by mouth and absorbed through the digestive tract. It is the most common and convenient method of drug delivery.
• Rectal: An enteral route that involves administration of medication into the rectum, where it is absorbed by the lower GI tract. It is often used when oral administration is not feasible.
• Intramuscular: A parenteral route where medication is injected into a muscle, offering faster absorption than enteral routes. Common for vaccines and certain pain medications.
• Intravenous: A parenteral route that delivers medication directly into the bloodstream. It provides the most rapid onset of action and is used for critical care, emergencies, and precise dosing.
