There are several types of drugs for treating status epilepticus: 1. Diazepam. Whether treating status epilepticus in adults or children, intravenous injection of Diazepam is the most effective first - choice drug. Adults can receive a slow intravenous injection at a rate of 2 - 4 milligrams per minute until the seizure stops or the total dose reaches 20 - 30 milligrams. After the injection of Diazepam, 80 - 100 milligrams can be added to 500 milliliters of 5% glucose solution and slowly infused intravenously at a rate of 40 milliliters per hour. 2. Clonazepam. Its efficacy is five times that of Diazepam, and its half - life is 22 - 32 hours. The initial adult intravenous dose is 3 milligrams. However, it has a relatively strong inhibitory effect on respiration and the heart, so extra attention is needed. 3. Phenobarbital. It can be used in both adults and children and can be administered by intramuscular injection. 4. Phenytoin. It has a slow onset but a long - lasting effect. It is effective for status epilepticus, does not affect consciousness, and does not inhibit respiration. It can be used in combination with Diazepam.
