Oral drugs for lowering intracranial pressure include diuretics, such as hydrochlorothiazide tablets, furosemide tablets, glucocorticosteroids, acetazolamide and so on. 1. Hydrochlorothiazide tablets: Hydrochlorothiazide tablets are mainly used in edematous diseases to excrete excessive sodium and water in the body, which can eliminate edema. Common diseases include congestive heart failure, nephrotic syndrome, etc. It can also be used to reduce intracranial pressure. 2. Furosemide tablets: Furosemide tablets are mainly used in edematous diseases, such as acute cerebral edema, congestive heart failure, cirrhosis and other diseases, can also be used to reduce intracranial pressure. 3. Glucocorticoid: it has anti-inflammatory and dehydrating effects, mainly used in immune-related diseases. 4. Acetazolamide: inhibit cerebrospinal fluid secretion so as to reduce intracranial pressure, can be used for idiopathic intracranial hypertension, also can be used for the treatment of glaucoma. Increased intracranial pressure, clear cause for the cause of the treatment at the same time given to lower the cranial pressure treatment, mild high cranial pressure can be treated with oral medication, severe need for intravenous cranial pressure reduction therapy, and there is a risk of cerebral herniation, it is recommended that timely medical treatment, do not blindly self-medication.
