No specific medications exist to treat glioblastomas. However, certain conditions require medical treatment. For seizures, the patient usually is started on levetiracetam (Keppra), phenytoin (Dilantin), or carbamazepine (Tegretol). Levetiracetam is often used because it lacks the effects on the P450 system seen with phenytoin and carbamazepine, which can interfere with antineoplastic therapy. Vasogenic cerebral edema is typically managed with corticosteroids (eg, dexamethasone), usually in combination with some form of antiulcer agent (eg, famotidine, ranitidine). The American Academy of Neurology's practice parameters state that prophylactic antiepileptic drugs (AEDs) should not be administered routinely to patients with newly diagnosed brain tumors (standard) and should be discontinued in the first postoperative week in patients who have not experienced a seizure.
