Mechanism of action

This is an administration route rather than a single drug entity; chemotherapy agents (commonly methotrexate, cytarabine, or hydrocortisone) are injected directly into the intrathecal space via lumbar puncture or ventricular reservoir. This approach achieves high local concentrations in the cerebrospinal fluid while minimizing systemic exposure, allowing treatment of CNS-penetrating cancers and prophylaxis of meningeal involvement in hematologic malignancies.
