Corticosteroids are often utilized in the management of increased intracranial pressure (ICP), particularly in patients with conditions like brain tumors or cerebral edema. These medications help reduce inflammation and can lead to a decrease in the volume of the brain tissue swelling, effectively lowering ICP. The mechanism by which corticosteroids exert this effect involves stabilizing cell membranes and reducing the permeability of the blood-brain barrier, ultimately leading to diminished edema.

In contrast, increased hydration can contribute to rising ICP, particularly in patients with conditions that already predispose them to fluid overload. Physical therapy does not address the underlying issue of heightened intracranial pressure and primarily focuses on rehabilitation. Oxygen therapy, while important for patients with hypoxia, does not directly impact ICP levels. Therefore, corticosteroids remain the most appropriate pharmacological choice for treating increased intracranial pressure.
