Diazepam, lorazepam, and midazolam are three medications used to break active seizures, administered by healthcare professionals to manage the condition and prevent long-term complications.
Step-by-step explanation:
Three medications that are commonly used to break a seizure in an emergency situation include diazepam, lorazepam, and midazolam. These medications are considered anticonvulsants and are typically administered by healthcare professionals to manage active seizures, which is crucial for improving long-term prognosis and reducing the risk of brain damage. While these medications are effective, they are not usually self-administered; their use is specifically for patients who are actively seizing.
