What is the drug of choice for managing grand mal seizures when administered intravenously?

• A. Phenobarbital
• B. Diazepam (Valium)
• C. Lorazepam
• D. Fosphenytoin

Answer: (B)

The drug of choice for managing grand mal seizures when administered intravenously is diazepam. Diazepam is a benzodiazepine that has rapid onset and is effective in controlling acute seizure activity. Its mechanism of action involves enhancing the effect of the neurotransmitter GABA, leading to increased neuronal inhibition and a resultant reduction in seizure activity. In the context of managing seizures, particularly grand mal seizures, the rapidity of action is crucial because time is often of the essence in preventing complications associated with prolonged seizure episodes. Diazepam is favored because it can be quickly delivered intravenously, providing immediate relief. While other medications such as phenobarbital and lorazepam can also be used for seizure control, diazepam's rapid onset of action makes it particularly suitable in acute emergency situations. Fosphenytoin, while effective for seizure management as well, is typically used in circumstances where longer-term stabilization is needed rather than for immediate seizure control.
