Oral drugs to reduce intracranial pressure mainly include diuretic drugs, drugs to lower cranial pressure, hormones and so on. 1. Diuretic drugs: patients with high intracranial pressure can take some diuretic drugs as prescribed by the doctor, which can effectively reduce intracranial pressure through diuresis, and common oral medications are furosemide, acetazolamide, aminopterin and so on. 2. Drugs for lowering cranial pressure: Glycerol saline solution can be taken orally to lower the intracranial pressure. 3. Hormones: such as dexamethasone, hydrocortisone, prednisone used orally or intravenously can reduce cerebral edema and help to alleviate the increased intracranial pressure, but hormones have no clear efficacy on cerebral edema caused by craniocerebral trauma. Increased intracranial pressure is mostly caused by intracranial infections, tumors, and immune-inflammatory reactions, etc. In addition to medication as prescribed by the doctor, lowering intracranial pressure also requires treatment of the primary disease. Therefore, if you have increased intracranial pressure, go to the Neurology Department of a regular hospital in time to diagnose the cause of the disease, and then follow the doctor’s instructions to choose the appropriate treatment.
