The fastest medications to reduce edema are the following, such as mannitol, tachypnea, albumin and glucocorticoids, which are chosen differently depending on the condition. In the case of cerebral edema caused by cranial injury, mannitol and tachyphylaxis are usually used to dehydrate and reduce swelling. If the cerebral edema is very serious, mannitol 125ml and tachyon 20mg can be used alternately every 8 hours. If the swelling is generalized due to hypoproteinemia, intravenous albumin is usually the fastest way to reduce the swelling. If the nerve edema is caused by nerve injury or contusion, glucocorticoid drugs can be applied to reduce inflammation and swelling, commonly used are dexamethasone, methylprednisolone and other drugs.
