Purpose

Temozolomide is primarily used to treat glioblastoma multiforme, an aggressive brain cancer, and other malignant gliomas. The goal is to reduce tumor size, slow cancer progression, and improve patient survival rates.

Indications

• Diagnosed glioblastoma multiforme
• Other malignant gliomas such as anaplastic astrocytoma
• Patients who have not responded to other treatments or who are inoperable

Preparation

• No specific fasting required.
• Inform your doctor of any other medications or supplements you are taking.
• Routine blood tests may be required to check liver and kidney function and to ensure adequate blood cell counts.

Procedure Description

1. Patient Setup: The patient is comfortably seated or lying down.
2. IV Placement: An intravenous (IV) line is inserted into a vein, usually in the arm.
3. Preparation: The temozolomide dose is calculated and prepared according to the patient's body weight.
4. Administration: The drug is administered slowly through the IV line over a specified period.
5. Monitoring: The patient is monitored for any adverse reactions during and shortly after the infusion.
